PURPOSE:To provide a titled material having high sensitivity to all matching colors and to decrease contamination with dyes after processing by forming a silver halide emulsion layer of specific compds. CONSTITUTION:The silver halide emulsion has the high sensitivity to all the matching colors and the contamination with the dyes after the processing can be decreased if said emulsion is formed of the compd. contg. at least one kind of the compd. expressed by the formula I and the compds. expressed by the formulas II-IV. In the formulas, Z; a nonmetal atom group necessary for forming an oxazole nucleus, benzoxazole nucleus, etc.; R<1>; an alkyl group which may be substd., R<2>; an alkoxycarbonylalkyl group, phenyl group, etc., R<3>, R<4>; a hydrogen atom, alkyl group, etc., which may be the same or different, U, V, W, Y; a hydrogen atom, halogen atom, etc., X<->; acid anion, m; 1 or 2, m is 1 when an inner salt is formed, n; 1 or 2, n is 1 when an inner salt is formed, l; 1 or 2, l is 1 when an inner salt is formed. |
