Description

United States Patent 3,238,043 VESCQUS PROCESSING SQLUTIUN Marilyn Levy, Red Bank, N.J., assignor to the United States of America as represented by the Secretary of the Army No Drawing. Filed July 6, 1961, Ser. No. 122,355 2 Claims. (Cl. 96-63) (Granted under Title 35, US. Code (1952), sec. 266) The invention described herein may be manufactured and used by or for the Government for governmental purposes, without the payment of any royalty thereon.
This invention relates to viscous processing solutions adapted for use by photographic processors and to separation systems utilizing the viscous processing solutions.
An object of the invention is to obtain a viscous processing solution that when sandwiched between a plastic or paper overlay and the gelatino-silver halide emulsion layer of a photosensitive film bearing a latent image will result in a separation system that can be rolled up as it is processed. Alternatively, where immediate scanning or reproduction after processing is desired, the object is to obtain a separation system wherein the viscous processing solution remains on the plastic or paper overlay when the overlay is stripped from the gelatino-silver halide layer of the photosensitive film bearing a latent image leaving the film free of viscous solution or marks of any kind.
It has been found that the foregoing objectives can be obtained by providing a viscous processing solution comprising a normally free-flowing solution of a resinous material and photographic processing agent admixed with a material incompatible with the resin solution. The viscous processing solution can be developing type, fixing type or combined developing-fixing type depending on the photographic processing agent selected. The viscous processing solution can be incorporated into a separation system by a number of methods.
One method involves the sandwiching of a viscous developing solution between a plastic or paper overlay and the gelatino-silver halide emulsion layer of a photosensitive film that has been exposed to light. When the plastic or paper coating is peeled oil, it takes with it, in a cohesive layer, the viscous processing solution leaving the developed gelatino-silver halide emulsion layer free of solution or marks of any kind. Alternatively, the sandwich type separation system can be rolled up as it is processed. Removal or inactivation of the residual silver halide can then be accomplished in a similar manner. That is, a viscous processing solution containing a fixer or stabilizing agent is sandwiched between the exposed and developed gelatino-silver halide emulsion layer of a photosensitive film and an overlay of plastic or paper. When this overlay is removed, the viscous processing solution sticks to the overlay rather than the gelatino-silver halide emulsion layer. One step processing can also be accomplished using a combined developer and fixer in the viscous processing solution.
Another method of incorporating the viscous processing solution into a separation system involves the application by painting, coating, spraying or the like of the processing solution directly onto the exposed gelatinosilver halide emulsion layer of a photosensitive film. The plastic or paper overlay is then placed over the viscous solution. When the overlay is pulled oil, the viscous solution forms a cohesive film that adheres preferentially to the plastic or paper overlay. This procedure can also be reversed and the viscous processing solution can be applied to the overlay. The coated overlay is then pressed in contact with the film until the desired processing is accomplished. When the overlay is peeled off, the viscous material will again preferentially stick to the overlay.
The separation systems utilizing the viscous processing solutions are based on the fact that free flowing colloidal solutions of resins will form a cohesive rubbery gel when mixed with other materials that are incompatible with the resin solution. The viscous processing solutions of the lnvention are especially useful for photographic processing in moving vehicles as for example, in airplanes in flight as spillage of processing solutions is greatly reduced or eliminated. Furthermore, there is no necessity of washing the film free of the processing material in immediate scanning as the stripping operation leaves the film clean and free of viscous solution or marks of any kind. The viscous processing solutions and separation systems using the viscous processing solutions can also be adapted to conventional film processing methods.
Some preferred embodiments of this invention are shown in the following examples.
Example 1.-A viscous fixing solution is prepared from the following ingredients- Ingredient: Amount A. Sodium polyacrylate (12.5% in water) cc 300 B. Ammonium thiocyanate grams 110 C. Lauryl trimethyl ammonium chloride (50% in isopropanol) -cc 6-20 When C above is added to the free-flowing solution of A and B above, there results a viscous fixing solution of a slightly rubbery texture. The solution is then coated onto the gelatino-silver halide emulsion layer of a photosensitive film bearing a latent image, and the viscous fixing solution is covered with a carrier or protective layer which may be cloth, paper, plastic, etc. This separation system may be rolled up the protective layer stripped from the film leaving the film free of viscous solution or marks of any kind.

Example 3.--A viscous developing solution is prepared from the following ingredients.
Ingredient: Amount A. Sodium acrylate cc 300 B. Sodium sulfite grams 30 C. Hydroquinone c do 15 D. Sodium hydroxide do 10 E. Phenidone do 3 F. Polyvinyl pyrrolidone (45% in water) cc 15 The Example 4.A viscous fixing solution is prepared from the following ingredients.

This solution can be sandwiched between the exposed film and a plastic or cloth overlay with the same results as in Example 1. Furthermore, the polyvinyl alcohol can be the resinous material and the sodium canboxy methyl cellulose, the incompatibilizing material.
Example 6.A viscous developing solution is prepared from the following ingredients.
Ingredient: Amount, grams A. Sodium carboxy methyl cellulose 10-30 B. Tri ethyl phosphate 5-30 C. Methyl-para-aminophenol 3 D. Sodium sulfite 100 E. Hydroquinone 10 F. Sodium carbonate 40 G.

Water 100-1000 When B above is added to a free-flowing solution from A, C, D, E, F, G, and H, there results a viscous developing solution of a slightly rubbery texture. In this example, in lieu of using methyl cellulose as the incompatibilizing material, 1-10 grams of either polyvinyl alcohol or zein can be used.
Example 11.A viscous fixing solution is prepared from the following ingredients.
Ingredient: Amount, grams A. Polyvinylpyrrolidone 1-50 B. Bone glue 0.05-5 C. Potassium iodide 50-200 D.
