Description
i PHOTOGBNERATION DB AMINES FROM OR-AMINOACETOPHENONES The application is directed to curable base-catalyzed compositions comprising a-amino ketone compounds as latent bases, as well as to a process for curing said compositions, inter alia in combination with polymerizable components by radicals. Among the thermosetting resins, epoxy resins have found extremely wide applications due to the variety of chemical reactions and materials that can be used to cure and the very different properties that result. More specifically, their excellent mechanical and chemical properties, high adhesive strength, good heat resistance, and high electrical resistance have made them extremely useful. They are widely used in applications such as adhesives, coatings, thermo-fixes or photoprotective layers (see for example CA May, Epoxy Resins, Chemistry and Technology, 2nd Ed. Marcel Dekker, New York, 1988) . The curing of epoxy resins can be affected by polyaddition reactions that result in coupling as well as entanglement. The most widely used agents for this purpose are active hydrogen compounds such as polyamines, polyacids, polymercaptans, polyphenols, anhydrides, isocyanates, etc. These reactions are in principle stoichiometric reactions between an active hydrogen in the curing agent and an epoxide group, such that the curing agent is usually present in relatively high concentrations. Of course, these polyaddition reactions can be catalyzed by appropriate catalysts. It is possible to use, for example dicyandiamide, benzoguanamine or imidazole derivatives as catalysts for the reaction of epoxides with carboxylic acids. The anionic and cationic polymerization of epoxides occurs with a variety of bases and Lewis acids, as well as with numerous salts and complex initiators. In the case of base catalyzed polymerization, amines such as benzyldimethylamine, or 2,4,6-tris (dimethylaminomethyl) phenol and imidazole derivatives, are the most useful initiators. Secondary amines, such as pepiridine, diethanolamine and imidazole derivatives, which are first subjected to addition to the epoxy group by their labile hydrogens and then function as initiators, have also been employed. In the case of cationic polymerization, strong Bronsted acids, such as trifluoroethane sulfonic acid and a wide variety of Lewis acids, the most useful of which are boron trifluoride complexes, can catalyze the cationic polymerization of epoxides.
The unique property of the epoxides can be employed in image photophering applications if suitable photosensitive compositions are available. In principle, epoxides can not be cured by typical free radical chemistry and therefore can only be used in radical photopolymerization systems if suitable reactive groups such as vinyl ethers or acrylates are also present. This is not always convenient. Photochemically initiated reactions of epoxy groups require photoinitiators that can generate the appropriate starter species. Cationic photoinitiators of the onium type, for example diaryliodonium salts or triarylsulfonium salts, are well known and can be used for the cationic photoinitiator polymerization of epoxides. Although the cationic photopolymerization mechanism has real advantages such as oxygen insensitivity, it can not be used if basic materials are present in the uv curable formulations. Therefore, there is a need for efficient photogenerated base catalysts which can be used to cure epoxy-containing photosensitive compositions. The purpose of the present invention is first to provide a new process for photochemically generating tertiary amine catalysts which can be used for the basic catalysis of epoxide polysubstances and second, corresponding compositions. The photogenerated base catalysts are already known in the art (for example Pure and Appl. Chem. (Pure and Applied Chemistry) 1992, 64, 1239) and have been applied to photoprotective layer technology (for example EP-A-599 571 , JP-A 4330444 and EP-A 555 749). Amines are the most useful photogenerated bases known to date. However, some known photo-generators of amines such as substituted benzylcarbamates (examples are described in J. Org. Chem. 1990, 55, 5919) suffer from or suffer from insufficient absorption in the near UV region, which is a severe restriction for many. Applications. Although the photocatalysts have been proposed, they generate amines with higher absorption in the region between 300 and 400 nm see, for example, Polym. Mat. Sci. Eng. 1991, 64, 55 or Macromol. 1995, 28 365, can not always be used, because the recombination of the free amine and the carbonyl by-product to form an imine, can occur depending on the acidity of the formulation. Furthermore, they can only generate primary or secondary amines, which are not very efficient catalysts for poloxides to epoxies or for anionic epoxide polymerization. It is well known that tertiary amines are efficient base catalysts that can be employed in epoxide reactions, but few attempts have been made to generate them photochemically. Photolysis of tetraalkyl ammonium salts has been proposed as a method for photochemically generating tertiary amines (Polym, Mat, Sci. Eng. 1995, 72, 201). These compounds require long radiation times, have an unfavorable absorption spectrum and their structure can only be varied with difficulty. According to this, there is a need for efficient photogenerators of tertiary amines. In order to be useful, these compounds must exhibit low reactivity with the formulation before exposure to UV light. In particular, the storage stability of photosensitive compositions containing them should be high, and should not be less revealable after the previous drying step which is usually necessary to remove the solvent. They will have to have high absorption in the near UV region in order to generate the free amine efficiently under exposure conditions commonly employed in the "photoformation" imaging industry Finally, after irradiation, the generated base should show high catalytic activity in the thermal curing reaction The photolytic breakdown of specific ce-amino ketone compounds in radicals and the photopolymerization process for oleic unsaturated monomers and oligomers employing ketone compounds is known and described inter alia in US Patent Nos. 4,582,862 , 4,992,547 and 5,077,402 European Patent Application 555 749 describes the use of latent bases in hybrid systems, ie systems with cationically and radically polymerizable compounds US Patent No. 4,943,516, describes hybrid systems comprising a photoinitiator for radically polymerizable components and among others a curing agent for the epoxy component, as well as a process for curing the compositions. (4-Methylthiobenzoyl) -1-methyl-1-morpholino-ethane is named as an example of a photoinitiator for the free-radically polymerizable components. It has now been found that specific compounds, already known as initiators for the curing of radically polymerizable compositions, are also suitable as base generating compounds, that is to say as compounds that generate bases before irradiation ("photobase generators") and thus can used in reactions catalyzed by base. Accordingly, this invention relates to a composition, comprising: (A) co or latent base catalyst, at least one compound of formula I, II or III ffl Ar.- - ° C-? CXC? ' - iC? -Ar. 1 l I 1 («)

Suitable components (D) are also the amides of identical or different unsaturated carboxylic acids with aromatic, cycloaliphatic and aliphatic polyamines, which preferably have 2 to 6, especially 2 to 4, amino groups. Examples of these polyamines are ethylene diamine, 1,2- or 1,3-propylene diamine, 1,2-, 1,3-ol, 4-butylene diamine, 1,5-pentylenediamine, 1,6-hexylenediamine, octylenediamine, dodecylendi ina. , 1,4-diaminocyclohexane, isophorodiane, phenylenediamine, bisphenylenediamine, di - &; -aminoethyl ether, diethylenetriamine, triethylenetetraamine, di (β-aminoethoxy) - or di (S-a) inopropoxy) ethane.

Examples of these unsaturated amides are methylenebisacrylamide, 1,6-hexamethylene bisacrylamide, diethylenetriaminetris ethacrylamide, bis (methacrylamidopropoxy) ethane, β-methacrylamidoethyl methacrylate and N - [(β-hydroxyethoxy) ethyl] acrylamide. Suitable polyamides and unsaturated polyesters are derived, for example, from maleic acid, and from diols or diamines. Some of the maleic acid can be replaced by other dicarboxylic acids. They can be used together with ethylenically unsaturated comonomers, for example styrene. The polyesters and polyamides can also be derived from dicarboxylic acids and from ethylenically unsaturated diols or diamines, especially those having relatively long chains, for example from 6 to 20 carbon atoms. Examples of polyurethanes are those composed of saturated or unsaturated diisocyanates and of unsaturated or saturated diols, respectively. Polybutadiene and polyisoprene and their copolymers are known. Examples of suitable comonomers are olefins such as ethylene, propene, butene and hexene (meth) acrylates, acrylonitrile, styrene or vinyl chloride. Polymers with (meth) acrylate groups in the side chain are also known. For example, they can be reaction products of epoxy resins based on novolacs with (meth) acrylic acid or they can be homo- or copolymers of vinyl alcohol or its hydroxyalkyl derivatives which are esterified with (meth) acrylic acid or can be homo and copolymers of (meth) acrylates that are esterified with hydroxyalkyl (meth) acrylates. The photopolymerizable compounds can be used alone or in any desired mixture. It is preferred to use mixtures of poly (meth) acrylates. Binders can also be added to the novel compositions and this is particularly convenient when the photopolymerizable compounds are liquid or viscous substances. The amount of binder for example can be 5-95%, preferably 10-90% and especially 40-90% by weight, based on the total solids content. The selection of binder is made depending on the field of application and the properties required for this field, such as the capacity for development in solvent, aqueous and organic systems, adhesion to substrates and sensitivity to oxygen.
Examples of suitable binders are polymers having a molecular weight of about 5000 to 2000000, preferably 10000 to 1000000. Typical examples are: homo- and copolymers of acrylates and methacrylates, for example copolymers of methyl methacrylate / ethyl acrylate / methacrylic acid, poly (alkyl methacrylates), poly (alkyl acrylates); cellulose esters and cellulose ethers such as cellulose acetate, cellulose acetobutyrate, methyl cellulose, ethyl cellulose, polyvinyl butyral, polyvinyl formal, cyclized rubber, polyethers such as polyethylene oxide, polypropylene oxide and polytetrahydrofuran; polystyrene, polycarbonate, polyurethane, chlorinated polyolefins, polyvinyl chloride, vinyl chloride / vinylidene chloride copolymers, copolymers of vinylidene chloride with acrylonitrile, methyl methacrylate and vinyl acetate, polyvinyl acetate, copoly (ethylene vinyl acetate), polymers such as polycaprolactam and poly (hexamethylene adipamide) and polyesters such as poly (ethylene glycol terephthalate) and poly (hexamethylene glycol succinate). The unsaturated compounds can also be used as a mixture with non-photopolymerizable film-forming components. They can, for example, be polymers or their typical drying solutions in organic solvents, for example nitrocellulose or cellulose acetobutyrate. However, they can also be chemically and / or thermally curable resins (thermo-curable), examples being polyisocyanates, polyepoxides and melamine resins. The use of thermo-curable resins is important concomitantly for use in these systems (also called hybrid systems), which are photopolymerized in a first stage and then interlaced by post-heat treatment in a second stage. In hybrid systems (as well as those comprising anionic and radical curable components as well as those comprising chemically and thermally curable components) the photopolymerizable mixtures in addition to the photoinitiator, may include various additives. Examples of these are thermal inhibitors which are used to prevent premature polymerization, examples being hydroquinone, hydroquinone derivatives, p-methoxyphenol, S-naphthol or sterically hindered phenols, such as 2,6-di-tert-butyl-p-cresol. In order to increase storage stability in the dark, it is possible for example to use copper compounds, such as copper naphthenate, stearate or octoate, phosphorus compounds, for example triphenylphosphine, triethyl phosphite, triphenyl phosphite or tribenzyl phosphite. To exclude atmospheric oxygen during polymerization in hybrid systems, it is possible to add paraffin or similar wax-like substances which, being of inadequate solubility in the polymer, migrate to the surface at the beginning of the polymerization and form a transparent surface layer that prevents the entry of air. It is also possible to apply an oxygen impermeable layer. Light stabilizers that can be added in a small amount are UV absorbers, for example those of the hydroxyphenylbenzotriazole, hydroxyphenebenzophenone, oxalamide or hydroxyphenyl-s-triazine type. These compounds can be used individually or in mixtures, with or without sterically hindered amines (HALS) with convenient (low) basicity, for example bis (? -octyloxy-2,, 6,6-tetramethylpiperidyl) succinate. Examples of these UV absorbers and light stabilizers are 1.2- (2"-hydroxyphenyl) benzotriazoles for example 2- (2" hydroxy-5"-methylphenyl) -benzotriazole, 2- (3", 5"-di-terbutil- 2"-hydroxyphenyl) benzotriazole, 2- (5" -tert-butyl-2"-hydroxyphenyl) benzothiole, 2- (2" -hydro?

The invention therefore also provides compositions that in addition to the latent base photoinitiator (A) also provide at least one additional photoinitiator for radical polymerization (E) and / or other customary additives. The compounds of formulas i, II and III are suitable as photobase generators. Accordingly, they can be used in a process to carry out base catalyzed reactions. The process is characterized in that a composition as described above is irradiated with light having wavelengths from 200 to 700 nm. The invention therefore also relates to a process for photochemically generating bases in base-catalyzed polymerization reactions, characterized in that a compound of the formula I, II or III as defined above is added, as a latent base, to the mixture at polymerize and irradiate with light of wavelength from 200 to 700 nm, to generate the base. The process can be carried out in the presence of a sensitizer selected from the group of carbonyl compounds having a triplet energy of 225-310 kJ / mol. These sensitizing compounds are described above and are referred to as component (C) of the novel composition. In some cases, it is advantageous to heat the composition during or after irradiation. The entanglement reaction can often be accelerated, in this way in another of its aspects the invention therefore relates to a method for curing compositions comprising (A) a compound of the formula I, II or III as defined above, (B) at least one organic compound that is capable of reacting in a base catalyzed addition reaction or substitution reaction; and (C) optionally a sensitizer, wherein (1) the composition is irradiated with light having a wavelength of 200 to 700 nm to generate a base catalyst from the photosensitive precursor of formula I, II or III and ( 2) is subsequently cured in thermal form using as a catalyst the photogenerated base in step (1).
The photosensitivity of the novel compositions generally ranges from about 200 nm to 700 nm. Suitable radiation is present, for example, in sunlight or light from artificial light sources. Consequently, a large number of very different types of light source are employed. Both point and joint sources ("lamp mats") are suitable. Examples are carbon arc lamps, xenon arc lamps, mercury lamps of medium, high and low pressure, possibly adulterated with metal halides (metal-halogen lamps), metal vapor lamps excited with microwaves, excimer lamps, super-actinic fluorescent tubes, fluorescent lamps, incandescent argon lamps, electronic flash lamps, photographic flood lamps, electron beams and X-rays produced by synchrotrons or laser plasma. The distance between the lamp and the substrate to be exposed according to the invention can vary depending on the intended application and the type and output of the lamp and for example can be laser light sources of 2 cm to 150 cm, for example excimer laser They are especially convenient. Laser in the visible region can also be used. In this case, the high sensitivity of the novel materials is very advantageous. By this method it is possible to produce printed circuits in the electronics industry, lithographic offset printing plates or relief printing plates and also materials for photographic image recording. The temperature for the treatment stage (2) can be in the range from room temperature
(approximately 25 ° C) at 180 ° C. The preferred temperature range depends on the reaction catalyzed by particular base. For example, for acid / epoxy systems, the temperature range is from 70 ° C to 160 ° C, for epoxy / thiol reactions, the temperature range is from room temperature to 120 ° C. The invention also relates to a process as described above, wherein the thermal curing step (2) is followed by a developing step (3). The development means removing non-interlaced parts of the composition. The person with skill in the specialty is familiar with the appropriate development methods. It is also possible to conduct the above procedure such that the photochemical step (l) is followed by a development step (3), before the thermal cure step (2) or such that the steps (1), (2) ) and (3) are followed by a second stage of thermal curing (4). An additional base catalyst, other than a compound of the formulas I, II or III or a precursor of said catalyst, can of course be added to the composition as a co-catalyst for the thermal step (2). These catalysts, for example, are imidazole derivatives, triazine derivatives, guanidine derivatives. Specific examples are 2PHZ, 2E4MZ-CNS, (imidazole derivatives of Shikoku Chemicals), acetoguanamine, benzoguanamine, dicyandiamide. The use of these thermal catalysts is described, for example, in: U.S. Pat. No. 4,943,516, JP 7-278266, JP 1-141904, JP 3-71137, JP 6-138655, JP 5-140251, JP 6-67430, JP 3-172317, JP 6-161108), JP 7-26183) . Since the compounds of the formulas i, II and III are also useful as radical photoinitiators, as already mentioned above, the process can also be carried out in a hybrid system, ie a mixture of anion and radical curable components. Accordingly, in this process, the composition may additionally comprise a monomer, oligomer or radical polymerizable polymer (D). The photobase generators according to the present invention are especially useful in applications where high thermal stability and / or good solvent resistance, low electrical conductivity, good mechanical properties are required, as is the case for example in welding protective layers, conformal coatings, encapsulation of electrical devices, stereolithography, etc. In addition, they are useful for the photoformation of image compositions, using a base-catalyzed or dual-curing mechanism (by radical and anionic), wherein the ce-amino ketone compounds at the same time are photoinitiators of photobase radicals and generators (such compositions they are described previously). The invention also provides compositions additional to components (A) and (B) comprising at least one ethylenically unsaturated, photopolymerizable compound that is emulsified, dispersed or dissolved in water. Aqueous prepolymer dispersions, radiation curable of this type, are commercially available in numerous variations. This term is taken to mean a dispersion of water and at least one prepolymer there dispersed. The concentration of water in these systems is, for example, from 5 to 80% by weight, in particular from 30 to 60% by weight. The radiation-curable prepolymer or prepolymer mixture is present, for example, in concentrations of from 95 to 20% by weight, and in particular from 70 to 40% by weight. The total of the percentages indicated for water and prepolymers in these compositions in each case is 100, to which the additives and additives in various amounts are added depending on the intended application. The water-dispersible, radiation-curable film-forming prepolymers which frequently also dissolve are for dispersions of aqueous prepolymers, are monofunctional or polyfunctional ethylenically unsaturated prepolymers which are known per se, can be initiated by free radicals and contain, for example, 0.01 to 1.0 mole of polymerizable double bonds per 100 grams of prepolymer and have an average molecular weight for example of at least 400, in particular from 500 to 10,000. Depending on the intended application, however, prepolymers having higher molecular weights may also be suitable. For example, use is made of psylesters containing polymerizable CC double bonds and having a maximum acid number of 10, polyethers containing polymerizable CC double bonds, hydroxyl-containing products of the reaction of a polyepoxide containing at least two epoxide groups per molecule with at least one carboxylic acid or », ß-ethylenically unsaturated, polyurethane
(meth) acrylates, and ac, ethylene-unsaturated acrylic copolymers containing acrylic radicals, as described in EP-A-12 339. Mixtures of these prepolymers can also be employed. Also suitable are the polymerizable prepolymers described in EP-A-33 896, which are the thioether adducts of polymerizable prepolymers having an average molecular weight of at least 600, a content of carboxyl groups from 0.2 to 15% and a content of from 0.01 to 0.8 mol of double polymerizable CC bonds per 100 g of prepolymer. Other suitable aqueous dispersions based on specific alkyl (meth) crylate prepolymers are described in EP-A-41 125; Suitable water-dispersible, radiation-curable prepolymers made from urethane acrylates are described in DE-A-2 936 039. Water-borne or water-soluble protective layer compositions are described, for example, in JP-A- 4-169985, JP-A 4-169986, JP-A 4-169987 and JP-A 4-31361. These aqueous radiation curable prepolymer dispersions can include additives, dispersion assists, emulsifiers, antioxidants, light stabilizers, colorants, pigments, fillers, for example talc, gypsum, silica, rutile, carbon black, zinc oxide. , and iron oxides, reaction accelerators, leveling agents, lubricants, wetting agents, thickeners, matting agents, defoamers and other assistants that are customary in coating technology. Suitable dispersion assistants are water-soluble organic compounds of high molecular mass containing polar groups, examples being polyvinyl alcohols, polyvinyl pyrrolidone and cellulose ethers. Emulsifiers can be used as nonionic emulsifiers and possibly also ionic emulsifiers. The compositions according to the invention can also be used for radiation curable powder coatings. The powder coatings can be based on the resin compositions described, including hybrid systems. A UV curable powder coating can be formulated by mixing polymers with carboxylic acid groups, with epoxides and adding the photobase generator (or mixtures thereof). Hybrid powder coatings can also be formulated by adding solid resins and monomers containing reactive double bonds to polymers containing carboxylic acid groups and epoxides and photobase generators (alone or in combination with radical initiators). Resins and monomers containing reactive double bonds, for example, are maleates, vinyl ethers, acrylates, acrylamides and mixtures thereof. The powder coatings may also comprise binders as described for example in DE-A-42 28 51 and in EP-A-636 669. The powder coatings may additionally comprise white or colored pigments. For example, titanium dioxide, preferably rutile titanium dioxide, may be used in concentrations of up to 50% by weight in order to give a cured powder coating of good hiding power. The process usually comprises electrostatic or tribostatic spraying of the powder onto the substrate, for example metal or wood, melting the powder by heating and after a smooth or uniform film has been formed, radiation coating the coating with ultraviolet and / or visible light , using for example medium pressure mercury lamps, metal halide lamps or xenon lamps. The irradiation can be carried out while the coated articles are still hot to accelerate the curing, but it is also possible to irradiate after cooling and a second heat treatment (at a different site after assembling different parts). A particular advantage of the radiation curable powder coatings against their thermosetting counterparts is that the flow time after fusing of the powder particles can be retarded if desired in order to ensure the formation of a high gloss coating., smooth or even. In contrast to thermo-curable systems, radiation curable powder coatings can be formulated to melt at lower temperatures without the undesired effect of shortening their useful life. For this reason, they are also suitable as coatings for thermosensitive substrates, for example wood or plastic. In addition, the powder coating formulations may also include UV absorbers and other additives. Appropriate examples were listed above. The photopolymerizable compositions can be used for various purposes, for example as printing inks, as a transparent finish, as a white finish, for example for wood or metal, as a coating material, inter alia for paper, wood, metal or plastic, as a powder coating, as a coating curable in daylight for marking roads and marking buildings, for photographic reproduction techniques, for holographic recording materials, for image recording techniques or for producing printing plates that can be developed with organic solvents or aqueous alkalis, to produce masks for screen printing or screen printing, as dental filling compositions, as adhesives, including pressure sensitive adhesives, such as laminating resins, as a permanent etch protective layer or protective layer; as welding masks and photoforming dielectrics for even image to electrical circuits, for electronic circuits, to produce three-dimensional articles by mass curing (UV curing in transparent molds) or by stereolithography technique, to produce composite materials and other thick-film compositions, to coat or seal electronic components or as coatings for optical fibers. When coating hybrid curing system materials, mixtures of a prepolymer with polyunsaturated monomers are often used, which may additionally include a mono-unsaturated monomer as well. It is the prepolymer here that primarily dictates the properties of the coating film and by varying it, the skilled in the specialty is able to influence the properties of the cured film. The functions of polyunsaturated monomer as an entanglement agent that makes the film insoluble. The monounsaturated monomer functions as a reactive diluent which is used to reduce the viscosity without the need for a solvent. The novel photocurable compositions are suitable, for example, as coating materials for substrates of all types, for example wood, textiles, paper, ceramics, glass, plastics such as polyesters, polyethylene terephthalate, polyolefins or cellulose acetate, especially in the form of films. and also metals such as Al, Cu, Ni, Fe, Zn, Mg or Co and GaAs, Si or Si02, to which it is intended to apply a protective layer or by means of image exposure to generate a reproduced image. The coating of the substrates can be carried out by applying a liquid composition, a solution or a suspension to the substrate. The selection of solvents and the concentration depend mainly on the type of composition and the coating technique. The solvent must be inert, ie it must not undergo a chemical reaction with the components and must be capable of being removed again after coating in the course of drying. Examples of suitable solvents are ketones, ethers and esters such as methyl ethyl ketone, isobutyl methyl ketone, cyclopentanone, cyclohexanone, dioxane, tetrahydrofuran, 2-methoethanol, 2-ethoxyethanol, α-methoxy-2-propanol, 1-2. dimethoxyethane, ethyl acetate, n-butyl acetate and ethyl 3-ethoxypropionate. The solution is applied uniformly to a substrate by means of known coating techniques, for example by spin coating, dip coating, spatula coating or knife, curtain coating, brushing, spraying, especially electrostatic spraying, and reverse roll coating, and also by electrophoretic deposition. It is also possible to apply the photosensitive layer to a temporary flexible support for coating the final substrate eg a copper-coated circuit board by transferring the layer by lamination. The amount applied (coating thickness) and the nature of the substrate (layer support) depend on the desired field of application. The range of coating thicknesses, in general, comprise values of approximately 0.1 μm to more than 100 μm. The novel radiation sensitive compositions find application as a negative protective layer, which have a very high sensitivity to light and are capable of being developed in an aqueous alkaline medium without bloating. They are suitable as protective photocaps for electronic components (electro-coating protective layer, etching protective layer, welding protective layer), the production of printing plates, such as offset printing plates, flexographic and relief plates or screen printing and / or production of dyes, for use in chemical milling or as a protective micro-layer in the production of integrated circuits. The possible layer supports and the processing conditions of the coated substrates are equally varied. The compounds according to the invention also find application for the production of single or multiple layer materials for image recording or image reproduction (copies, reprography) which can be mono- or polychromatic. In addition, the materials are suitable for color test systems. In these technologies, it is possible to apply formulations containing microcapsules and for the production of radiation curing image can be followed by a thermal treatment and / or depression. Substrates employed for recording photographic information include for example cellulose acetate or polyester films, or polymer coated papers; substrates for offset printing forms, are specially treated aluminum, substrates for producing printed circuits are laminated with copper cladding and substrates for producing integrated circuits are silicon wafers or wafers. The thicknesses of layers for photographic materials and forms of offset printing, in general are from approximately 0.5 μm to 10 μm, while for printed circuits they are from 0.1 μm to approximately 100 μm. After the substrates are coated, the solvent is removed, generally by drying, to leave a protective photo coating on the substrate. The temperature range depends on the particular base catalyst reaction and should be less than the start temperature of the uncatalyzed reaction.
The term "in the form of image formation" includes both exposure through a photomask which comprises a predetermined pattern, for example a slide, exposure by a light beam (e.g. a laser beam), which for example moves under computer control over the surface of the coated substrate, producing an image in this manner, and irradiation with electron beams controlled by computer. Following the exposure as an image of the material and before development, it may be advantageous to carry out heat treatment for a short time. In this case, only the exposed sections are thermally cured. The temperatures for this post-exposure baking are in the range from room temperature
(approximately 25 ° C) up to 200 ° C and depending on the reaction catalyzed with particular base. Preferred temperatures for the reaction with epoxide acid are 100-160 ° C and for the thiol epoxide reaction from room temperature to 120 ° C. The period of thermal treatment in general is from 0.25 to 10 minutes. The photocurable composition can additionally be employed in a process for producing protective plates or protective photo-layers similar to those described for example in DE-A-40 13 358. After exposure and if implemented, heat treatment, the unexposed areas of the photosensitive coating they are removed with a developer in a way known per se. As already mentioned, novel compositions can be developed, inter alia, with aqueous alkalis. Particularly suitable aqueous alkaline developer solutions are aqueous solutions of tetralkyl ammonium hydroxides or alkali metal silicates, phosphates, hydroxides and carbonates. If desired, minor amounts of wetting agents and / or organic solvents can also be added to these solutions. Examples of typical organic solvents that can be added to developer liquids in small amounts are cyclohexanone, 2-ethoxyethanol, toluene, acetone and mixtures of these solvents. Another field where photocoating is employed is for coating metals, such as coating metal plates and tubes, cans and bottle caps, and light curing polymer coatings, for example floor or wall coverings with a PVC base. Examples of the curing of paper coatings are the colorless finishes of labels, disc covers and book covers.
The compositions and compounds according to the invention can be used for the production of optical switches and waveguides, where the development of a difference in the refractive index between irradiated and non-irradiated areas is used. The use of photocurable compositions for imaging techniques and for the optical production of information carriers is also important. In these applications, as already described above, the layer (wet or dry) applied to the support is irradiated through a photomask with UV or visible light, and the unexposed areas of the layer are removed by treatment with a solvent (= revealing). The application of the photo-stable layer to the metal can also be carried out by electrodeposition. The exposed areas are polymeric through interlacing and therefore insoluble and remain in the support. Proper coloring produces visible images. When the support is a metallized layer, the metal can, following exposure and development, mordentate in non-exposed areas or be reinforced by electrocoating. In this way it is possible to produce printed electronic circuits and protective photocaps. The invention further provides the use of the composition described above, for preparing pigmented and non-pigmented paints and varnishes, printing inks, powder coatings, printing plates, adhesives, dental compositions, waveguides, optical switches, systems for testing color, composite compositions, fiberglass cable coatings, stencils for screen printing, protective layer materials, for photographic reproductions, for encapsulating electronic and electrical components, for producing magnetic recording materials, for producing three-dimensional objects by stereolithography and as material for image recording, especially for holographic recordings. The preferred composition is used for the production of protective layer materials, welding masks, conformal coatings, protective coatings, powder coatings, overprint varnishes, glass fiber coatings, wave guides, printing plates, adhesives, inks, stencils for screen printing, reinforced composite materials, optical switches, color test systems, magnetic recording media, dental materials, or a procedure conducted as a stereolithographic or holographic process. The compounds of formulas I, II and III are base generators that can be photochemically activated and exhibit surprisingly excellent latency before exposure to UV light. In addition, they have high absorption in the near UV region and high catalytic activity after photorupture of the substituted benzoyl portion of the molecule. The following examples illustrate the invention in more detail. Parts and percentages as in the remainder of the description and in the claims, are by weight unless otherwise indicated. When alkyl radicals having more than three carbon atoms are mentioned without mention of specific isomers, the n-isomers are intended in each case. Example 1: Photobase activity.
