Description
Oppfinnelsen vedrører en fremgangsmåte for fremstilling av relieffkopier på hvilket det lysfølsomme sjikt av et lysherdbart kopimateriale som inneholder en fotopolymeriserbar forbindelse eller en negativ arbeidende, lysfølsom diazo-forbindelse, blir bildemessig eksponert og de ueksponerte sjiktområder blir utvasket ved hjelp av en fremkaller. The invention relates to a method for producing relief copies on which the light-sensitive layer of a light-curable copy material containing a photopolymerizable compound or a negative working, light-sensitive diazo compound is image-wise exposed and the unexposed layer areas are washed out using a developer.
Slike lysherdbare materialer, spesielt de fotopolymeriserbare materialer er etter den bildemessige eksponering i det minste ennå ikke fullstendig utherdet. Det ble funnet at i avhengig-het av ventetiden mellom eksponeringen og fremkallingen opp-trer klare ulikheter i kilelengden av kopierte halvtonetrinn-kiler. Særskilt utpreget er slike variasjoner ved eksponeringen med laserlys, f.eks. av en argon-ione-laser. Such light-curable materials, especially the photopolymerizable materials, are at least not yet completely cured after the image exposure. It was found that, depending on the waiting time between the exposure and development, clear differences occur in the wedge length of copied half-tone step wedges. Particularly pronounced are such variations when exposed to laser light, e.g. by an argon-ion laser.
Det er kjent å variere forarbeidelsen av slike og lignende materialer. Således er det beskrevet i US-PS 3.286.025 overføring av bilder til fotopolymeriserbare materialer med elektronstråling. Sjikt som ble bestrålt, blir fortrinnsvis oppvarmet for en tid, f.eks. 5 minutter ved 136°C, for å få It is known to vary the processing of such and similar materials. Thus, it is described in US-PS 3,286,025 the transfer of images to photopolymerizable materials with electron radiation. Layers that were irradiated are preferably heated for a time, e.g. 5 minutes at 136°C, to get
en bedre kontrast ved den der anvendte metode for projektering av bildene. Følsomheten til sjiktet overfor elektronstråling blir ikke innvirket av oppvarming. a better contrast with the method used there for projecting the images. The sensitivity of the layer to electron radiation is not affected by heating.
Det er kjent andre lysfølsomme systemer som består av en forbindelse som ved eksponering avspalter en syre og syreherdende harpikser, ved hvilke f.eks. er beskrevet i DE-PS 14 47 913 Other light-sensitive systems are known which consist of a compound which on exposure splits off an acid and acid-curing resins, in which e.g. is described in DE-PS 14 47 913
og 15 22 503, som oppvarmes etter eksponeringen for å påskynde gjennomherdingen av harpiksene av syren. and 15,22,503, which is heated after the exposure to accelerate the curing of the resins by the acid.
Oppgave for foreliggende oppfinnelse er følgelig å foreslå en fremgangsmåte av nevnte art som alltid gir ved forarbeiding av de der nevnte materialer likartede resultater under anvendelse av mindre eksponering. The task of the present invention is therefore to propose a method of the aforementioned kind which always gives similar results when processing the materials mentioned there using less exposure.
Oppfinnelsen utgår fra en fremgangsmåte for fremstilling av relieffkopier ved hvilket det lysherdbare sjikt til et kopimateriale som inneholder en fotopolymeriserbar blanding, en fotodimeriserbar polymerforbindelse eller et diazoniumsalt-polykondensasjonsprodukt, blir bildemessig eksponert og hvoretter de ueksponerte sjiktområder blir utvasket ved hjelp av en fremkaller. The invention is based on a method for producing relief copies in which the light-curable layer of a copy material containing a photopolymerizable mixture, a photodimerizable polymer compound or a diazonium salt polycondensation product is image-wise exposed and after which the unexposed layer areas are washed out using a developer.
Fremgangsmåten i henhold til oppfinnelsen erkarakterisertved at man oppvarmer sjiktet under eksponeringen eller etter eksponeringen en kort tid til forhøyet temperatur og deretter fremkaller. The method according to the invention is characterized by heating the layer during the exposure or after the exposure for a short time to an elevated temperature and then developing.
Oppvarmingen skjer fortrinnsvis hurtigst mulig etter eksponeringen, dvs. innen en tid opptil omtrent en time deretter. Med særskilt fordel kan også oppvarmingen skje samtidig med eksponeringen. The heating preferably takes place as soon as possible after the exposure, i.e. within a time of up to approximately one hour thereafter. With particular advantage, the heating can also take place at the same time as the exposure.
Temperaturen skal ligge mellom 50 og 180°C, fortrinnsvis mellom 70 og 120°C. The temperature should be between 50 and 180°C, preferably between 70 and 120°C.
Varigheten av oppvarmingen kan ligge mellom 5 sekunder ogThe duration of the heating can be between 5 seconds and
10 minutter, fortrinnsvis mellom 5 sekunder og 2 minutter.10 minutes, preferably between 5 seconds and 2 minutes.
Jo kortere tidsintervallet mellom eksponeringen og oppvarmingen er, desto kortere kan oppvarmingstiden avpasses. The shorter the time interval between exposure and heating, the shorter the heating time can be adjusted.
Oppvarmingen kan skje på i og for seg kjent måte, f.eks. ved opphetede plater eller valser, ved varmluft eller infrarød-stråling. The heating can take place in a manner known per se, e.g. by heated plates or rollers, by hot air or infrared radiation.
De lysfølsomme materialer som skal forarbeides ved fremgangsmåten ifølge oppfinnelsen består av et lysfølsomt sjikt som fortrinnsvis befinner seg på en sjiktbærer. Som lysfølsomme sjikt foretrekkes fotopolymeriserbare sjikt. Disse inneholder som vesentlig bestanddel en polymeriserbar forbindelse med minst to endestående etyleniske umettede dobbeltbindinger, The light-sensitive materials to be processed by the method according to the invention consist of a light-sensitive layer which is preferably located on a layer carrier. Photopolymerizable layers are preferred as light-sensitive layers. These contain as an essential component a polymerisable compound with at least two terminal ethylenic unsaturated double bonds,
et polymert bindemiddel og en fotoinitiator som under inn-virkning av aktinisk stråling har evne til å innlede radika-lisk polymerisasjon av den etyleniske umettede forbindelse. Som ytterligere bestanddeler kan sjiktet inneholde stabilisa- a polymeric binder and a photoinitiator which, under the influence of actinic radiation, has the ability to initiate radical polymerization of the ethylenic unsaturated compound. As additional components, the layer can contain stabilizers

Examples include: maleate resins, polymers of N-(p-tolyl-sulfonyl)-carbamic acid-(3-methacryloyloxy-ethyl) ester and mixture polymers of these and similar monomers with other monomers as well as styrene-maleic anhydride mixture polymers. Methyl methacrylate-methacrylic acid mixture polymers and mixture polymers of methacrylic acid, alkyl methacrylates and methyl methacrylate and/or styrene, acrylonitrile and others, as well as those described in DE-OS 20 64 080 and 23 63 806.
Bindemiddelmengden er generelt 20-90, fortrinnsvis 4 0-80 vekt-% av bestanddelene i sjiktet. The amount of binder is generally 20-90, preferably 40-80% by weight of the components in the layer.
Det er generelt gunstig å holde innvirkningen av luftoksygenet lavest mulig under lyspolymeriseringen av det fotopolymeriserbare sjikt, dvs. fortrinnsvis å forhindre etterdiffusjon av luftoksygenet i sjiktet. Dette er særskilt viktig når man - f.eks. ved eksponering gjennom projeksjon eller med laserstråling - arbeider uten vakuumkopirammer. I tilfelle av anvendelse av blandinger i form av tynne kopisjikt anbe-fales å påbringe ved egnet, for oksygen lite gjennomtrengelig dekkfilm. Denne kan være selvbærende og blir avtrukket før fremkallingen av kopisjiktet. For dette formål er f.eks. polyesterfilmer egnet. Dekkfilmen kan også bestå av et materiale som oppløser seg i fremkallervæsken eller som lar seg i det minste fjerne på de ikke herdede steder ved fremkallingen. Slike egnede materialer er f.eks. vokser, polyvinylalkohol, polyfosfater, sukker osv. It is generally advantageous to keep the influence of the air oxygen as low as possible during the light polymerization of the photopolymerizable layer, i.e. preferably to prevent post-diffusion of the air oxygen in the layer. This is particularly important when - e.g. by exposure through projection or with laser radiation - works without vacuum copy frames. In the case of using mixtures in the form of thin copy layers, it is recommended to apply a suitable covering film that is impermeable to oxygen. This can be self-supporting and is subtracted before developing the copy layer. For this purpose, e.g. polyester films suitable. The covering film can also consist of a material which dissolves in the developer liquid or which can at least be removed in the unhardened places during development. Such suitable materials are e.g. waxes, polyvinyl alcohol, polyphosphates, sugar, etc.
Som fotodimeriserbare substanser kommer fremfor alt kanelsyre-derivater i betraktning, spesielt kanelsyreester av poly-hydroksyforbindelser som polyvinylcinnamat. Kopimaterialer av denne art er beskrevet i GB-PS 695.197. As photodimerizable substances, cinnamic acid derivatives come into consideration, especially cinnamic acid esters of polyhydroxy compounds such as polyvinyl cinnamate. Copy materials of this kind are described in GB-PS 695.197.
Kopimaterialer på basis av diazoniumsalt-polykondensasjonsprodukter kan likeledes anvendes. Copy materials based on diazonium salt polycondensation products can also be used.
Som diazoniumsalt-polykondensasjonsprodukter er egnet konden-sasjonsprodukter av kondensasjonsdyktige aromatiske diazoniumsalter, f.eks. av difenylamin-4-diazoniumsalter med alde-hyder, foretrukket formaldehyd. Med særskilt fordel anvendes blandingskondensasjonsprodukter som foruten diazoniumsalt-enhetene inneholder ytterligere andre, ikke lysfølsomme en-heter som er avledet av kondensasjonsdyktige forbindelser, spesielt aromatiske aminer, fenoler, fenoletere, aromatiske tioetere, aromatiske hydrokarboner, aromatiske heterocykliske forbindelser og organiske syreamider. Disse kondensasjons-produkter er beskrevet i US-PS 3.867.147. Generelt er alle diazoniumsalt-polykondensasjonsprodukter egnet som er beskrevet i US-PS 4.186.017. Suitable diazonium salt polycondensation products are condensation products of condensable aromatic diazonium salts, e.g. of diphenylamine-4-diazonium salts with aldehydes, preferably formaldehyde. With particular advantage, mixed condensation products are used which, in addition to the diazonium salt units, contain further other, non-photosensitive units which are derived from condensation-capable compounds, in particular aromatic amines, phenols, phenol ethers, aromatic thioethers, aromatic hydrocarbons, aromatic heterocyclic compounds and organic acid amides. These condensation products are described in US-PS 3,867,147. In general, all diazonium salt polycondensation products described in US-PS 4,186,017 are suitable.
De lysfølsomme sjikt av disse kopimaterialer kan dessuten inneholde bindemiddel, fargestoff, indikatorer, pigmenter, sta-bilisatorer, fuktemiddel og andre vanlige tilsetninger. Bindemidlet kan være vannoppløselig eller vannuoppløselig. Fortrinnsvis anvendes vannuoppløselige harpikslignende bindemidler, spesielt i kombinasjon med de foretrukne blandingskondensasjonsprodukter av diazoniumsalter. Eksempler på egnede bindemidler er polyalkylakrylater, metakrylsyre-alkylmetakrylat-blandingspolymerisater, poly-merer med sidestående sulfonyluretangrupper, fenolharpiks, ureaharpikser, melaminharpikser, epoksyharpikser, polyuretan, polyvinylester og polyvinylacetaler. The light-sensitive layers of these copy materials can also contain binders, dyes, indicators, pigments, stabilizers, wetting agents and other common additives. The binder can be water-soluble or water-insoluble. Water-insoluble resin-like binders are preferably used, especially in combination with the preferred mixed condensation products of diazonium salts. Examples of suitable binders are polyalkyl acrylates, methacrylic acid-alkyl methacrylate mixture polymers, polymers with adjacent sulfonylurethane groups, phenol resin, urea resins, melamine resins, epoxy resins, polyurethane, polyvinyl ester and polyvinyl acetals.
Mengdeandelen av diazoniumsalt-polykondensasjonsprodukt ligger generelt ved 10 til 100, foretrukket 20 til 95 vekt-%, mengden av bindemidlet er 0 til 90, fortrinnsvis 5 til 80 vekt-% av det totale sjikt. The amount of diazonium salt polycondensation product is generally 10 to 100, preferably 20 to 95% by weight, the amount of the binder is 0 to 90, preferably 5 to 80% by weight of the total layer.
Arten av sjiktbærere retter seg etter anvendelsesformålet for det lysfølsomme materialet. For fremstilling av flate trykkplater blir generelt aluminium anvendt som fortrinnvis bærer et anodisk fremstilt porøst oksydsjikt. Aluminiumet blir hensiktsmessig før anodiseringen oppruet mekanisk, kjemisk eller elektrolytisk. Anodiseringen skjer på kjent måte, f.eks. i svovel- og/eller fosforsyre, fortrinnsvis under slike betingelser at et oksydsjikt med en sjiktvekt The type of layer supports depends on the intended use of the light-sensitive material. For the production of flat printing plates, aluminum is generally used, which preferably carries an anodically produced porous oxide layer. The aluminum is suitably roughened mechanically, chemically or electrolytically before the anodisation. The anodization takes place in a known manner, e.g. in sulfuric and/or phosphoric acid, preferably under such conditions that an oxide layer with a layer weight
2 2
fra ca. 0,5 til 10 g/m fås.from approx. 0.5 to 10 g/m available.
Fortrinnsvis blir oksydsjiktet utsatt for en forbehandling før påføringen av det lysfølsomme sjikt for forbedring av de trykketekniske forhold,.spesielt hydrofilien, f.eks. med silikater eller polyvinylfosfonsyre. Besjiktingen av bære-materialet skjer på kjent måte ved påsprutning, stenkning, ved hjelp av valser, spaltdyser, farvekniv eller ved støpe-påføring. Preferably, the oxide layer is subjected to a pre-treatment before the application of the light-sensitive layer to improve the printing technical conditions, especially the hydrophilicity, e.g. with silicates or polyvinylphosphonic acid. The coating of the carrier material takes place in a known manner by spraying, sprinkling, with the help of rollers, slit nozzles, color knife or by cast application.
Foruten aluminium kan også anvendes stål, sink, kopper, forkrommet stål og forkrommet kopper, polymerfolier, f.eks. av polyetylentereftalat eller celluloseacetat, eller sikttrykk-bærere, f.eks. perlongas eller nikkelsikter. In addition to aluminium, steel, zinc, copper, chrome-plated steel and chrome-plated copper, polymer foils, e.g. of polyethylene terephthalate or cellulose acetate, or screen printing carriers, e.g. perlongas or nickel sieves.
Påføringen av bilder til kopimaterialet skjer på kjent måte, f.eks. ved kontakteksponering under et transparentforlegg. Herved anvendes vanlige lyskilder, som kullbuelamper, xenon-lamper, med metallhalogenider dotert kvikksølvhøytrykks-lamper og lignende. The application of images to the copy material takes place in a known manner, e.g. by contact exposure under a transparent cover. In this way, ordinary light sources are used, such as carbon arc lamps, xenon lamps, mercury high-pressure lamps doped with metal halides and the like.
Med fordelt kan påføringen av bilder også skje med laserlys, f.eks. med en argon-ione-laser. Ved denne eksponeringsart oppnås ved fremgangsmåten i henhold til oppfinnelsen en særskilt høy løsning av virkningen ved eksponeringen. With distributed, the application of images can also be done with laser light, e.g. with an argon-ion laser. With this type of exposure, the method according to the invention achieves a particularly high resolution of the effect of the exposure.
I ramme av foreliggende fremgangsmåte er for bildeeksponering egnet generelt aktinisk lys, dvs. stråling i området nært ultrafiolett og kortbølget synbart lys. In the context of the present method, generally actinic light is suitable for image exposure, i.e. radiation in the near-ultraviolet and short-wave visible light range.
Fremkallingen av eksponerte og oppvarmede kopimaterialer skjer på kjent måte ved utvasking av de ueksponerte sjiktområder med en fremkaller. Sammensetningen til fremkalleren tilpas-ses etter naturen og oppløselighet av det lysfølsomme sjikt. Egnede fremkallere er organiske oppløsningsmidler eller opp-løsningsmiddelblandinger, vann, som kan inneholde mindre mengder organisk oppløsningsmiddel eller fuktemiddel, og spesielt alkaliske eller svakt sure vandige oppløsninger som kan inneholde buffersalter, nøytralsalter, organiske oppløsningsmidler, fuktemidl.er, fargestoffer og andre vanlige tilsetninger. Foretrukket er fremkallere som er fri for organiske oppløsningsmidler. The development of exposed and heated copy materials takes place in a known manner by washing out the unexposed layer areas with a developer. The composition of the developer is adjusted according to the nature and solubility of the light-sensitive layer. Suitable developers are organic solvents or solvent mixtures, water, which may contain small amounts of organic solvent or wetting agent, and especially alkaline or weakly acidic aqueous solutions which may contain buffer salts, neutral salts, organic solvents, wetting agents, dyes and other common additives. Developers that are free of organic solvents are preferred.
Ved oppfinnelsen blir det oppnådd at herdingen av de eksponerte sjiktområder blir øket i en slik grad at eksponeringstiden kan minskes med omtrent halvdelen i forhold til nød-vendig tid uten oppvarming. Ved laserbestråling kan enda større forskjell oppnås. Som ytterligere virkning av oppvarmingen inntrer en klar bedre gjennomherding av det eksponerte sjiktområdet. Denne fordel utvirker seg særskilt ved fremstilling av trykkplater, spesielt flattrykkplater, som skal anvendes for trykking av det herdede bildesjikt. With the invention, it is achieved that the hardening of the exposed layer areas is increased to such an extent that the exposure time can be reduced by approximately half in relation to the necessary time without heating. With laser irradiation, an even greater difference can be achieved. As a further effect of the heating, there is a clear better hardening of the exposed layer area. This advantage is particularly effective in the production of printing plates, especially flat printing plates, which are to be used for printing the hardened image layer.

The following examples illustrate the invention. Parts by weight (wt) and parts by volume (vd) are in the ratio of g to ml.

The number of fully cured wedge steps to a halftone step wedge at the exposure and the immediately following development was 3.
Når en plate av samme art ble forarbeidet på samme måte, men hvor platen mellom eksponering og fremkalling ble oppvarmet i et oppvarmingsapparat i 7 sekunder ved 80°C, så ble det oppnådd 7 kiletrinn. When a plate of the same kind was prepared in the same way, but where between exposure and development the plate was heated in a heating device for 7 seconds at 80°C, 7 wedge steps were obtained.
Prøvetrykking og opplagstrykking ble gjennomført på en Heidelberger Offset-trykkerimaskin GTO med Dahlgren-fukteverk og var 150.000 ark. Ved den mellom-oppvarmede plateøkte opplaget til 200,000 ark. Test printing and edition printing were carried out on a Heidelberger Offset printing machine GTO with Dahlgren dampener and were 150,000 sheets. At the intermediate-heated plate the circulation increased to 200,000 sheets.

ble uthelt på en horisontalt anordnet glassplate mellom tre-rammer til en tykkelse slik at det ble oppnådd en folie med en tykkelse på ca. 1 mm etter fullstendig tørkning. was poured onto a horizontally arranged glass plate between wooden frames to a thickness so that a foil with a thickness of approx. 1 mm after complete drying.
Den fullstendige transparente trykkefolie ble eksponert i en vakuum-kopiramme gjennom en kombinert strek-/raste-/skrift-negativmønster (Linjeraster: 56 linjer/cm) i 10 minutter. Som lyskilde tjente et røreksponeringsapparat med tett til hverandre liggende lysstoffrør på 40 W i avstand av 5 cm. The full transparent printing film was exposed in a vacuum copy frame through a combined line/hash/print negative pattern (Line screens: 56 lines/cm) for 10 minutes. A tube exposure apparatus with 40 W fluorescent tubes lying close to each other at a distance of 5 cm served as the light source.
For fremkalling av den eksponerte trykkefolie ble anvendt en blanding av 60 vd etanol, 20 vd n-propanol og 20 vd vann. For fremkalling av små prøve-trykkefolier har vist seg egnet en myk pensel. For noe større plate ble anvendt en plyss-tampong. A mixture of 60 vd ethanol, 20 vd n-propanol and 20 vd water was used for developing the exposed printing foil. A soft brush has proven suitable for developing small test printing foils. For a slightly larger disc, a plush tampon was used.
Etter 10 minutters fremkalling med penselen i den beskrevne oppløsningmiddelblanding fikk en et kantskarpt relieff, hvilket gjenga også de fineste detaljer av mønsteret. Relieff-dypden var ved den her anvendte fremkallingsmetode 0,4 mm. After 10 minutes of development with the brush in the solvent mixture described, a sharp-edged relief was obtained, which also reproduced the finest details of the pattern. With the development method used here, the relief depth was 0.4 mm.
Når en likeledes plate etter eksponeringen ble oppvarmet 3 minutter ved 95°C og eksponeringstiden ble forkortet til 5 minutter, så ble det oppnådd et likeledes til bedre resultat. Den etteroppvarmede platen oppviste en klart hårdere overflate. When a similar plate after the exposure was heated for 3 minutes at 95°C and the exposure time was shortened to 5 minutes, a similarly better result was obtained. The reheated plate showed a clearly harder surface.
