摘要:
A silver halide photographic material having a hydrophilic colloidal layer containing a dispersion of fine solid particles of a dye is disclosed, said dye being represented by formula (I): ##STR1## wherein L represents a nitrogen atom or a group composed of 1, 3, 5 or 7 substituted or unsubstituted methine group(s) connected via a conjugated double bond(s); E represents O, S, or N--R.sup.9 ; and R.sup.0 through R.sup.9 are as defined in the specification. The dye of formula (I) colors a specific hydrophilic colloidal layer without being diffused to other layers and is rapidly decolorized or washed off on development processing.
