Kokai Tokkyo Koho JP 03181944 A2 7 Aug 1991 Heisei, 37 pp. (Japan). CODEN: JKXXAF. CLASS: ICM: G03C007-42. APPLICATION: JP 89-322401 12 Dec 1989. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) In processing of an imagewise exposed Ag halide color photog. material by color development followed by processing with a bleach-fixing soln. and/or a fixing soln. contg. a thiosulfate, the total Ag coating amt. of the photog. material is ￡7. 3638-64-0 and 33513-44-9 are cas registry numbers of chemicals which are used as reagents here.5 g/m2 and the bleach-fixing soln. and/or the fixing soln. contg. (1) at least one compd. selected from R1COR2 (I; R1 = H, alkyl, alkenyl, aralkyl, cycloalkyl, aryl, heterocyclyl; R2 = a group listed in R1, CO2H, ester, acyl, CONH2; or R1R2 forming a ring), R3R4C:CR5R6 (II; R3-R5 = a group listed in R2, halogen, ether, SO3H, sulfinyl, sulfonyl, cyano, NO2, SO2NH2; R6 = an electron-withdrawing group; or R3R4, R4R5, R5R6, R6R3 forming a ring), R7C(:NR9)R8 (III; R7-R9 = a group listed in R1, NH2, CO2H, ester, acyl, (thio)ether, OH; X = an anion; n = 0, 1; or R7R8, R8R9, or R9R7 forming a ring), and azolinium salts (IV; R10 = a group listed in R1; R11 = a group listed in R2, halogen, ether, cyano, SO3H, NO2, ester, NO2, dialkylamino; Z = a heterocyclic ring consisting of C, N, O, S, and/or Se atoms; Y = an anion; m = 0, 1; or R10 forming a ring by bonding with atoms in the Z ring) and at least one compd. selected from bisulfites, sulfites, and metabisulfites and (2) at least one adduct of I-IV with a bisulfite salt. The photog. processing provides fast desilverization, little bleach fogging, stable processing soln. with little long-term degrdn., even in rapid processing. .
