Abstract
A silver halide photographic light-sensitive material is disclosed. The photographic material contais fine solid particles of a compound represented by a formula of A=L.sub.1 -L.sub.2 =L.sub.3).sub.m B wherein A represents an acidic mother nucleus of 2-pyrazoline-5-one; B represents an aryl group which is substituted at 4th position thereof with an amino group having at least one of alkenyl, alkknyl or heterocyclic group or with a cyclic amino group; L.sub.1, L.sub.2 and L.sub.3 each represent a methine group; m is an integer of 0 or 1; wherein A contains a carboxyphenyl, sulfonaminodophenyl or aminosulfonylaminophenyl group. The compound is used in a filter layer in the photographic material.
Claims7
