Abstract
A silver halide photographic material contains in a hydrophilic colloid layer a 4-arylazooxazoline-5-one compound or/and a 2-arylazo-3-butene-4-olide compound in the form of a dispersion of fine solid particles or a composition with an oil or/and a polymer latex. The compounds not only can selectively color a particular layer alone but also can be speedily decolorized and/or eluted in the course of development processing. In addition, they have no undesirable effects on photographic characteristics.
