PURPOSE:To obtain the title material which has safety in a yellow safety lamp and high sensitivity against the laser ray source and high contrast by incorporating a specified compd. in an emulsion layer contg. a silver halide having a specified mean particle size and a specified degree of monodispersion. CONSTITUTION:The silver halide particle contd. in the silver halide emulsion layer has the mean particle size of 0.05-0.5mum, and the degree of monodispersion of a range of 5-20. At least one kind of the compds. shown by formulas I, II and III, and the compd. shown by formula IV are incorporated in the emulsion layer. In formula I, R1 and R2 are each aryl group, R is an org. binging group. In formula II, R21 is an aliphatic group, R22, P1 and P2 are each hydrogen atom. In formula III, Ar is an anti-dispersible group or aryl group, R31 is a substd. alkyl group. In formula IV, R1 and R2 are each aryl group, R is an org. binding group. The photosensitive material which has the safety in the yellow safety lamp, and the high sensitivity against the laser ray source and the excellent high contrast is obtd. by mounting the emulsion layer on a supporting body. |
