Definitions
- This invention is concerned with a photographic process and more particularly with the use of certain colloid insolubilizing developing agents to make a photographic image or resist.
- the non-silver halide containing layer could be coated on the support on which the image or resist is desired thus avoiding contaminants on the support which could affect the silver halide.
- the resist might be provided on a metal plate to serve as a basis for etching the metal to obtain a relief printing plate or the like.
- One object of this invention is to provide a photographic rocess for obtaining a photographic image or resist by the transfer of certain wandering gelatin-insolubilizing oxidized developing agents from a developing silver halide emulsion to a separate gelatin layer thereby insolubilizing the gelatin at distances of up to more than 0.10 mm. from the site at which oxidation of the developer takes place.
- Another object of this invention is to provide certain gelatin-solubilizing agents which insolubilize gelatin imagewise in a separate gelatin layer in contact with a developing silver halide emulsion.
- a further object is to provide a method of making a photographic resist on a support carrying a non-silver halide containing gelatin layer.
- a still further object is to provide a resist in a non-silver halide containing gelatin layer.
- Another object is to provide a hardened gelatin resist on a support which can be used in printing processes.
- the above objects are attained by exposing a silver halide emulsion and then developing the emulsion with a developer whose oxidation products are capable of in solubilizing gelatin at distances removed from the site of oxidation of the developer. While the emulsion is developing, it is contacted against a gelatin layer on a separate support for a time sulficient for the oxidation products of the developer to harden the gelatin imagewise. The non-silver halide containing gelatin layer is then separated from the silver halide emulsion and washed in warm water to remove the unhardened areas to to reveal a resist image in the non-solver halide containing gelatin.
- tanning developers can be used in our process such as, for example, 1,4-di hydroxy benzene compounds such as, hydroquinone, chlorohydroquinone, bromohydroquinone, toluhydroqui none, morpholine methyl hydroquinone, etc.
- 1,4-di hydroxy benzene compounds such as, hydroquinone, chlorohydroquinone, bromohydroquinone, toluhydroqui none, morpholine methyl hydroquinone, etc.
- gelatin tanning developers which are inoperative in our process are catechol, chlorocatechol, methylcatechol,
- this process which is particularly useful with a separate gelatin layer on another support can be used to obtain a thicker gelatin resist than is normally obtained by having a non-silver halide containing gelatin layer under the silver halide emulsion on the same support so that when the silver halide emulsion is developed and the unexposed portion is washed off, the gelatin undercoat would also be hardened imagewise.
- the unhardened non-silver halide containing gelatin layer may be used as an overcoat over the silver halide emulsion for certain purposes. For instance, it might be used to provide a monochrome image from silver halide sensitized photographic material without using expensive color films. It often happens in graphic arts applications that the line or half-tone images in color are desired without the costly or time-consuming conventional processing of color materials.
- the non-silver halide containing layer can be pigmented or can contain a mordant and dye. The Wandering oxidation products from the silver halide layer harden the non-silver halid containing gel layer in the image areas so that when the unhardened areas are removed, a pigmented image remains.
- this gelatin would be substantially unhardened gelatin.
- the gelatin of the silver halide emulsion should also be substantially unhardened gelatin to avoid transfer of hardener to the nonsilver halide containing gelatin.
- the silver halide carrying colloid could be any of the well-known alkali-permeable colloids used for photographic purposes as carriers for silver halide.
- the coverage of the silver halide emulsion is not critical and can be varied depending upon the use intended. A useful range is about 50 to 500 mg./ft. gelatin and about to 300 mg./ft. silver.
- the silver halide emulsion can be any of the well known silver halide emulsions including silver chloride, silver bromide, silver chloroiodide, silver chlorobromide, silver chlorobromoioclide, silver bromoiodide, etc. It will be appreciated that unhardened, direct positive emulsions of the type described in P. I. Hillson, US. Patent 3,062,651, may be utilized to obtain direct positive images. In emulsions of this type, a non-hardening fogging agent such as stannous chloride, formamidine sulfinic acid, or the like may be used.
- the developing agent may be incorporated in the silver halide emulsion or the non-silver halide containing layer and development attained by using an alkaline activator, or development may be carried out by immersing the exposed photographic emulsion in a conventional alkaline developing bath provided the oxidized developing agent is one of those identified above as a wandering insolubilizing developing agent.
- Typical activator baths for the photographic emulsion containing the developing agent comprise, for example, an aqueous solution of an alkaline material, such as sodium carbonate, sodium hydroxide, potassium carbonate, potassium hydroxide, mixtures of sodium hydroxide and sodium sulfite, etc.
- Suitable baths can comprise, for example, an aqueous solution containing about 1 percent sodium hydroxide and 5 percent sodium sulfite.
- a particularly advantageous method for carrying out the invention is to incorporate an alkaline material in the non-silver halide containing layer and the wandering developing agent in the silver halide emulsion.
- a useful amount of alkali metal salt or similar alkaline material incorporated in the non-silver halide containing layer is 35 mols/mole of silver in the emulsion.
- the layers may be moistened and contacted together to provide the alkaline material necessary to oxidize the developing agent contained in the silver halide layer which results in development of the exposed emulsion and hardening of the non-silver halide containing layer.
- Typical of the activator solutions which can be used in our process are those disclosed in US. Patents 2,596,- 754, 2,596,756, 2,725,298, 2,739,890, 2,763,553, 2,835,- 575, 2,852,371, and 2,865,745.
- hydroquinone compounds which have alkali splittable groups thereon to stabilize the hydroquinone during storage may be incorporated in the emulsion. These compounds release hydroquinone in the presence of alkali and may be used in whole or in part to replace the hydroquinone or hydroquinone derivative incorporated in the silver halide emulsion in the non-silver halide containing layer or in the processing solution.
- auxiliary developing agent can be used along with a hyd-roquinone developing agent in order to improve the speed without affecting the operation of our invention.
- Typical auxiliary developing agents include 3-pyrazolidone developing agents known in the art as well as Elon (N-methyl-paminophenol sulfate) and the like.
- Useful auxiliary agents are 1-phenyl-3-pyrazolidone and l-phenyl-4,4-dimethyl-3-pyrazolidone.
- Suitable supports for the photographic emulsion comprise any of the well known supports such as cellulose ester film base (e.g., cellulose acetate butyrate, cellulose nitrate, cellulose acetate, cellulose acetate propionate, etc.), polyethylene, polypropylene, polystyrene, polyethylene terephthalate and other polyesters, paper, polyethylene coated glassine paper, glass, metal, polycarbonates, etc.
- cellulose ester film base e.g., cellulose acetate butyrate, cellulose nitrate, cellulose acetate, cellulose acetate propionate, etc.
- polyethylene polypropylene
- polystyrene polyethylene terephthalate
- paper polyethylene coated glassine paper
- glass glass
- metal polycarbonates
- the non-silver halide containing colloid layer can be coated on any of the above supports or may be coated on any support on which it is desirable to obtain a photographic image or resist.
- it could be coated on a metallic sheet such as copper, Zinc, aluminum or the like, or on some other surface for use as a template, etc.
- a particular advantage of this process is the ability to coat the gelatin or similar colloid on many surfaces which might contain contaminants which would be detrimental to the sensitivity, fog level, etc., of a silver halide emulsion.
- the gelatin could be coated on a curved surface such as a cylinder, and the developing silver halide emulsion wrapped around the cylinder to obtain the resist image on a curved support.
- Photographic developing out silver halide emulsions in our invention can also contain such addenda as chemical sensitizers, speed-increasing compounds, reducing agents, sensitizing dyes, etc., which are known to those skilled in the art. They may be blue sensitive, orthochromatic, panchromatic, infrared sensitive, etc., emulsions.
- gelatin is the preferred colloid for the nonsilver halide containing layer
- other alkali-permeable colloidal resins may be used which have the property of being imagewise hardened with tanning silver halide oxidized developers, for example, other proteins, such as casein, Zein, etc.
- our process can be used for making plates by means of stencils.
- the non-silver halide containing layer is coated on a porous support such as cloth, silk or highly porous paper and, after being hardened by contacting against the developing exposed silver halide emulsion, the unhardened areas are removed by washing in warm water leaving the support pervious to a printing ink in the areas wherein the gelatin has been removed.
- Prints are then made from the resulting stencil in the usual manner using a low viscosity ink with a resut that a large number of positive prints can be made.
- any other pigment or dye may be used including those which might not be normally compatible with a silver halide emulsion because of their efiect on the silver halide.
- pigment is used herein and in the appended claims, it is to be understood to include, for example, any insoluble organic and inorganic materials of nature such that they impart density to the copy.
- substantially unhardened gelatin gelatin which is not harder than would be the case with gelatin containing 0.25 ounce of formaldehyde (40 percent diluted 1:3 with water) or 0.7 gram dry formaldehyde per pound when freshly coated; or 0.1 ounce of the solution per pound for a sample aged 3 to 6 months.
- the resist image can be treated with hardeners or other known materials in order to make the image more resistant to abrasion or the like, if it is used for printing or to aid in protecting it against chemical action of an etching solvent or solution in the event that the support on which the resist is formed is to be etched.
- FIG. 1 discloses a support 10 having thereon an exposed silver halide photographic emulsion 11 showing a latent image 14.
- FIG. 2 shows the same photographic element of FIG. 1 after development with a wandering insolubilizing developer in which the exposed areas 14 have been developed.
- FIG. 3 illustrates the transfer of the oxidized dcveloper from developed image areas 14 to corresponding areas 12 of the colloid layer 13 on the support 15.
- FIG. 4 shows the support 15 carrying the colloid layer 13 with the image areas 12 in tanned colloid after the non-silver halide containing layer 13 has been stripped from the emulsion layer ll.
- FIG. 5 shows the image areas 12 in tanned colloid remaining after the untanned colloid layer 13 in the nonimage area has been washed off.
- EXAMPLE I A suitable film support was coated with a silver chloride emulsion having an unhardened gelatin vehicle, so that the support carried mg. of silver chloride and 400 mg. of gelatin/ft. when dry.
- a suitable film support was also coated with a dispersion of fine particles of carbon in unhardened gelatin to the extent of 1,000 mg. of gelatin/ft. and sutiicient car bon to give an optical density of 2.0 when dry.
- the exposed (to a line negative) silver chloride sensitized coating was placed in an aqueous solution of hydroquinone 1 percent, sodium sulfate (to prevent excessive softening of the gelatin) 3 percent at 7476 F. for 60 seconds at which time 3.6 g./sq. ft. of the solution was absorbed. Excess solution was removed by squeegeeing. Simultaneously, the carbon gelatin coating was placed in an aqueous solution of sodium carbonate 5 percent at 74-76 F. for 60 seconds at which time 5.3 g./sq. ft.. of the solution was absorbed. The excess was removed by squeegeeing. The two sheets were then placed face to face in intimate contact by pressure (mild) rollers.
- This solution was coated over Layer I at 5.0 Illl./fl;. to yield a silver coverage of 54 mg./ft. a gelatin coverage of 85 mg./ft. and a chlorohydroquinone coverage of 30 mg./ft.
- the element is exposed, activated and transferred as described below:
- Example III The process of Example I was repeated with a variety of developing agents. In all cases where hydroquinone or its derivatives were used, a mirror image of insolubilized gelatin containing carbon was formed. The oxidation product of the developing agent had wandered and insolubilized the gelatin in the gelatin carbon layer. In all cases where catchol or its derivatives were used, insolubilization of the gelatin occurred only in the image areas of the silver halide sensitized coating. There was no insolubilization of the gelatin in the gelatin carbon layer; no mirror image was formed. The oxidation product had not wandered.
- the non-silver halide containing gelatin on a tranparent support so that it can be viewed as either a normal or mirror image depending upon whether it is viewed through the base or above it.
- Our process has particular utility in obtaining images of almost any density or color or in any particular medium, if the medium can be dispersed in gelatin or other polymeric material that can be insolubilized by wandering oxidation products of developing agents.
- EXAMPLE IV A transparent film base was coated with an unhardened gelatino-silver halide emulsion so that 400 mg. of gel and 100 mg. of silver as silver halide covered the area of one square foot of base. Over this was coated a finely divided Ti0 pigment dispersed in unhardened gel (500 mg. TiO 400 mg. gel/ft). The photosensitive element was exposed through the base to a line image film negative and developed in an aqueous alkaline solution (5 percent Na CO containing 0.4 percent of hydroquinone. Development was carried out for 20 seconds at -76 F. followed by a 3-second rinse, a 10-second immersion in a 5 percent acetic acid stop bath and washofi in water at F. for 10-20 seconds, and dried.
- aqueous alkaline solution 5 percent Na CO containing 0.4 percent of hydroquinone. Development was carried out for 20 seconds at -76 F. followed by a 3-second rinse, a 10-second immersion in a 5 percent acetic acid stop bath and washof
- the image When viewed through the film base the image is the typical black silver; when viewed from the face of the image is the brilliant white of TiO It may be desirable in some cases to remove the black silver. If so, this is easily done by a quick bleach in dilute ferricyanide and halide followed by fixing and washing.
- EXAMPLE V A direct positive image is obtained by employing a fogged silver chloride emulsion as follows:
- the emulsion is coated on a cellulose acetate support at a coverage of 250 mg. of silver and 445 mg. of gelatin per square foot.
- a suitable film support is also coated with a dispersion of fine particles of carbon in unhardened gelatin to the extent of 1,000 mg. of gelatin/ft. and suflicient carbon to give an optical density of 2.0 when dry.
- Both the exposed (to a line negative) silver chloride and the carbon gelatin coating are placed in an aqueous solution of sodium carbonate 5 percent at 74-76 F. for 36-60 seconds. The excess is removed by squeegeeing The two sheets are then placed face to face in intimate contact by pressure (mild) rollers.
- a process of preparing a photographic resist comprising:
- colloid layer is a gelatin layer which is contiguous to the silver halide emulsion.
