CODEN: JKXXAF.Some commonly used reagents like 123876-15-3 and 53918-03-9 are used in this experiment. CLASS: ICM: G03C001-28. APPLICATION: JP 89-308714 28 Nov 1989. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) The title material comprising a support coated with one or more photosensitive Ag halide emulsion layers contains at least one compd. represented by structure I [Y1, Y2 = atoms for forming a 5- or 6-membered N-contg. heterocyclic ring; R1, R2 = a (un)satd. aliph. group; Q1, Q2 = atoms for forming 4-thiazolidinone, 4-oxazolidinone, etc.; L1-L3 = a (substituted) methine group, :CR3; R3 = Et, Me, ethoxy, etc.; X- = an anion; n, m = 0-3], at least one compd. represented by structure II [R4, R5 = (substituted) alkyl; A1-A6 = H, alkyl, alkoxy, halogen, Ph; among substituents A1-A6, adjacent substituents may together form rings; t = 0, 1; for inner salt, t = 0; X- = an anion], and at least one compd. represented by structure III [M = H, NH4, an alkali metal; R6 = H, alkyl, aryl; Z = atoms for forming a 5-membered (substituted) heterocyclic ring; the said heterocyclic ring may be fused to a benzene ring]. The title material shows high sensitivity. .
