Title: Photographic layers for the silver dyestuff bleaching process
IPC: G03C7/28
Filed: 1961-03-23
Abstract: 931,647. Photographic dye-bleach materials. CIBA Ltd. March 23, 1961 [March 24, 1960], No. 10736/61. Class 98 (2). The invention relates to multilayer material for the silver dye-bleach process wherein the red, green and blue sensitive layers contain respectively blue or cyan, red or magenta, and yellow dyestuffs, the dyestuff in the redsensitive layer being a phthalocyanine. The phthalocyanine dye may be used in its metalfree form or as its copper, cobalt, iron, manganese or nickel complex. When the silver bleach bath which is used to remove residual silver comprises a copper salt, the free phthalocyanine dyes and certain of the metal complexes are converted into the copper complex in this bath. This may be overcome by using a silver bleach bath comprising potassium ferricyanide, potassium bromide, secondary sodium phosphate and sodium sulphite. The metalfree phthalocyanines may then be converted into metal complexes after production of the image, by treatment with water-soluble salts of the metals. The benzene rings of the phthalocyanine dyes may be substituted with sulphonic acid, N,N-di-(#-hydroxyethyl)-sulphonamide, o-carboxy-benzamidomethyl, halogen, nitro, amino, arylamino, acylamino, phenyl, carboxylic acid or -SO 2 NHR groups, where R may be H, CH 3 , C 2 H 5 , C 4 H 9 , C 6 H 11 , C 9 ,H 19 , HO(CH 2 )n, where n is 2, 3 or 4, CH 3 O(CH 2 ) 3 -, CH 3 (CH 2 ) 11  - O (CH 2 ) 3 -, -(CH 2 ) 2 - O - SO 2 OH, -(CH 2 ) 2 N(C 2 H 5 ) 2 , -(CH 2 ) 3 -N(CH 3 ) CH 2 CH 2 -O-SO 2 -OH, CH 2 =CH-CH 2 -, 3-carboxy-n-hydroxyphenyl, or #-[3-chloro-5- (2,5 - disulphoanilino) - 2 :4 :6 - triazinylamino]-ethyl. The water-insoluble dyes may be incorporated into the emulsions by dissolving them in a water-soluble organic solvent such as alcohol, acetone or ethylene glycol, adding the solution to a molten gelatine solution, solidifying, shredding, washing out the solvent with water, remelting and adding to a gelatino-silver halide emulsion. Organic solvents such as methanol, ethanol, propanol, acetone, dioxane or a glycol, or dextrose may be added to the dye-bleach baths.
