Direct positive silver halide light-sensitive material

A direct positive silver halide photographic light-sensitive material comprising a support having coated thereon a light-sensitive unfogged, internal latent image silver halide photographic emulsion layer and a hydrophilic colloid layer, at least one of said layers containing a compound represented by the formula (I):

• ##STR23## ##STR24## wherein R.sub.1 is selected from the group consisting of a straight chain or branched chain substituted or unsubstituted alkyl group, a substituted or unsubstited cycloalkyl group, an alkenyl group, an alkynyl group and a substituted or unsubstituted aryl group;
• R.sub.2 is selected from the group consisting of a hydrogen atom, a straight chain or branched chain substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, an alkenyl group, an alkynyl group, and a substituted or unsubstituted aryl group;
• X.sub.1 and X.sub.2, which are the same or different, each is a divalent substituted or unsubstituted aryl group;
• and Y represents ##STR25## or a direct bond wherein the O or S is bonded to X.sub.1, R is selected from the group consisting of a straight chain or branched chain alkylene group or a cycloalkylene group, each of which may contain a double or triple bond, and R.sub.3 is selected from the group consisting of a straight or branched chain substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, an alkenyl group, an alkynyl group, and a substituted or unsubstituted aryl group, said compound (I) being present in a fogging amount which gives a suitable maximum density when the light-sensitive material is developed by a surface developing solution.
