Abstract

PURPOSE:To obtain high halftone quality by adding a specified color sensitizer to a silver halide photographic emulsion for lith development in an amount not causing color sensitization and dimethinemerocyanine in an amount causing color sensitization. CONSTITUTION:Oxacarboxyanine or imidazoxacarbocyanine represented by formula I or II is used in an amount not causing color sensitization. In the formulas, each of R1, R2, R8 and R9 is substituted alkyl having sulfo, each of R8 and R9 may be 1-3C alkyl, at least one of R8 and R9 is substituted alkyl having sulfoalkyl, each of R3-R6, R10 and R11 is H, halogen, 1-3C alkyl or the like, R7 is H or 1-3C alkyl, each of R12 and R13 is H, halogen, 1-4C alkoxycarbonyl, CN or the like, each of X and Y is an acid anion, and each of (m) and (n) is 0 or 1. A compound represented by formula III is also used in an amount causing color sensitization. In formula III, Z is atoms required to form a (substituted) 5-membered ring, A is O, S or the like, each of R15 and R16 is (substituted)alkyl or the like, and each of R17 and R18 is H, (substituted)alkyl or aryl. Thus, fine halftone images are obtd. over a long developing time even by processing with an automatic developing apparatus.
