Definitions
- sufiicient amounts of silver halide are complexed on the non-exposed parts of the negative which by diffusion-transfer in the non-light-sensitive receiving layer form a positive thanks to the reducing action of the developer which is catalyzed by the development nuclei present in the receiving layer.
- the compounds used according to the present invention can be incorporated into several layers of the receiving material as far, however, as their presence is compatible with the elements from which such repective layers are composed. In the circumstances, they can be added to an auxiliary layer, a baryta-layer or even to the paper itself, although preferably the applied process consists in incorporating them into the nuclei-containing layer. It was further observed that the favorable effect obtained with the basic polymers depends on the kind of nuclei used.
- Suitable developing nuclei which act as reducing nuclei for the complexed silver halide are i.a. colloidal silver and sulphur, colloidal metal sulfide such as copper-, nickel-, tinsilver and Zinc sulfide.
- Other compounds do not serve as nuclei but are able to form such nuclei by interaction with the diffusing silver complexes, either by reduction such as in the case of stannous chloride or by the formation of difficultly soluble compounds with sulfides or organic compounds which easily split off sulphur in the form of a bivalent ion such as in the case of thiosinamine.
- a further intensification of the image tone is attained, by adding to one of the layers of the positive material minor amounts of anti-fogging agents such as phenyl mercapto tetrazole, benzotriazole, mercapto benzotn'azole etc.
- anti-fogging agents such as phenyl mercapto tetrazole, benzotriazole, mercapto benzotn'azole etc.
- An advantage of the present invention consists therein that the usual developing baths and apparatus for the silver complex diffusion transfer process can be used Without any modification.
- prints can be made according to the system of one copy per negative such as described in the U.S. Patent specification 2,352,014 as well as a number of prints of one same negative according to the invention.
- the silver halide emulsions which are suitable for applying the new method comprises silver chlororomide emulsions, silver bromide emulsions containing silver chloride and silver chlohride emulsions which all of them can also contain small amounts of silver iodide.
- emulsions are used which mainly contain silver chloride. If, however, exposure times as short as possible are wanted, it is advantageous to use sensitive silver bromide emulsions which contain a small amount of silver chloride.
- binding agents can be used arabic gum, tragacanth gum, pectine, cellulose derivatives such as methyl cellulose, hydroxyl cellulose and carboxymethyl cellulose, polyvinyl alcohol, partly hydrolyzed polyvinyl esters, such as polyvinyl acetate, polyvinyl pyrrolidone, dimethylhydantoine formaldehyde resins etc.
- hydrophilic high-molecular substances can successfully be added to the image-receiving layer which for instance contains gelatin as binding agent in order to keep the adhering of the positive to the negative on a favorable level. Simultaneously, these highmolecular substances can bring along an improvement of the intensity of the positive probably in consequence of an increased reaction power of the nuclei-containing layer thus obtained.
- the positive material can be made in a very simple way since then only one layer must be applied to the support, eg paper.
- tanning of the colloid layer of the positive exerts an unfavorable influence on obtaining a uniform and sufiiciently high density on the positive.
- the addition of tanning agents to colloid layers indeed reduces the permeability of the latter and makes difiicult the diiTusion-transfer of the complexated silver salts of the light-sensitive layer to the receiving layer.
- an anti-hardening or softening agent to at least one of the layers of the negative or of the positive is very favorable for obtaining prints with a higher density.
- ditferent products which are known as softening or anti-hardening agents, such as urea, water-soluble thiocyanates, nitrates and halides such as potassium thiocyanate, potassium nitrate, sodium nitrate, potassium iodide, barium chloride, calcium chloride and magnesium chloride, ammonium salts, sodium salicylate, formamide, dimethyl formamide, ethylene chlorohydrin, chloral hydrate and alpha-naphthalene sodium sulfonate.
- urea This product can be added in amounts of 5 to 80% on the weight of binding agent present in the negative and/or of the positive layers.
- Example 1 A light-sensitive material is prepared by coating onto Gelatin 40 Colloidal zinc sulfide 0.24
- a second layer is applied from a 2% aqueous solution of carboxymethylcellulose.
- a sheet of light-sensitive material is image-wise exposed and in the known way brought into contact with a sheet of image-receiving material in the presence of a developer of the following composition:
- both sheets are separated from each other whereafter the light-sensitive sheet is brought in the same Way into contact with a second sheet of image-receiving material and is separated again therefrom after 5 sec.
- 10 sharp prints can be made from one same negative.
- Example 2 A light-sensitive material is prepared as in Example 1.
- An image-receiving material is prepared by coating onto a g./sq. m. paper a nuclei-containing layer from a suspension such as in Example 1 wherein however the poly-(1-vinyl-3-methyl imidazolium methyl sulphate) is replaced by 0.4 g. of poly-(l-methyl-4-vinyl-pyridinium methyl sulphate).
- a nuclei-containing layer from a suspension such as in Example 1 wherein however the poly-(1-vinyl-3-methyl imidazolium methyl sulphate) is replaced by 0.4 g. of poly-(l-methyl-4-vinyl-pyridinium methyl sulphate).
- Example 3 A light-sensitive material is prepared as in Example 1. An image-receiving material is prepared as in Example 1 but in the nuclei-containing layer composition 0.6 g. of
- poly-(1-vinyl-3-methyl imidazolium methyl sulphate) is replaced by 2.5 g. of poly-(1methyl-2-vinyl pyridinium iodide).
- 10 sharp prints can be obtained from one same negative.
- Example 4 i A light-sensitive material is prepared as in Example 1.
- An image-receiving material is prepared asin Example 1, but in the nuclei-containing layer composition 0.6 g. of poly-(1-vinyl-B-methyI-imidazolium methyl sulphate) is replaced by 0.4 g. of poly-(1-methyl-4-vinyl pyridinium iodide).
- 10 sharp prints can be obtained from one same negative.
- a process for obtaining multiple copies from an exposed silver halide emulsion layer which comprises contacting said emulsion layer with a first receiving layer containing development nuclei, a binding agent and a water-soluble basic polymeric quaternary salt, said polymeric quaternary salt having a polyvinyl chain, each monomeric unit of which is linked directly to a five to six-membered heterocyclic nucleus containing as heteroatoms only nitrogen atoms, one of said hetero-nitrogen atoms being a quaternary nitrogen atom, in the presence of a silver halide developer and'a silver halide solvent,
- a process for obtaining multiple copies from an exposed silver halide emulsion layer which comprises contacting said emulsion layer with a first receiving layer containing development nuclei, a binding agent, urea and a water-soluble basic polymeric quaternary salt, said polymeric quaternary salt having a polyvinyl chain, each monomeric unit of which is linked directly to a five to six-membered heterocyclic nucleus containing as heteroatoms only nitrogen atoms, one of said hetero-nitrogen atoms being a quaternary nitrogen atom, in the presence of a silver halide developer and a silver halide solvent, separating the layers and recontacting the silver halide emulsion layer with another of said receiving layers in the presence of said silver halide developer and a silver halide solvent.
- said emulsion layer contains a binding agent and about 580% by weight of said binding agent of a softening agent for said binding agent.
- heterocyclic nucleus is selected from the group consisting of pyridinium and imidazolium nuclei.
