Abstract
1,038,337. Photographic transfer material and process. EASTMAN KODAK CO. March 14, 1963 [March 14,1963],No. 10096/63. Heading G2C. Photographic light-sensitive material for use in a transfer process comprises a support coated first with a colloid layer containing a developing agent and an alkaline salt and then with a silver halide emulsion layer having dispersed therein a solution in an organic solvent of an organic compound or compounds which give a change of colour on oxidation or reduction. The exposed material is developed by heating in the presence of moisture and contacted with a receiving sheet whereby the coloured image developed in the emulsion layer is transferred to the receiving layer. The said organic compound may be (i) oxidized by the oxidation products of the used developer in the exposed areas or (ii) reduced by un-used developer in the unexposed areas. Examples of (i) are leuco dyes which are oxidized to the dye, 4-alkoxy-1-naphthols which self-condense to give a dye, a mixture of a substituted p-phenylene diamine and a colour coupler, or a 2-alkyl-5-alkyl-hydroquinone which is oxidized to the corresponding quinone which transfers with unoxidized hydroquinone to the receiving sheet where they react to form a dye. In the latter case the receiving sheet also may contain a substituted quinone. An example of (ii) is a 2-alkyl-5-alkyl-quinone which is reduced to a hydroquinone by the unused developer and forms a dye as above. The developing agent may be a 1 -phenyl-3 -pyrazolidone, a p-phenylene-diamine or a p-methylaminophenol sulphate. The alkaline substance may be sodium or potassium metaborate, or isopropylamine acetate, oxalate or citrate.
