ABSTRACT:
A practical, useful gelatino silver halide photo-sensitive material having incorporated therein a compound represented by the following formula: ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 each represent a hydroxyl group, a hydroxylamino group, an amino group, an alkylamino group of from 1-6 carbon atoms, said alkyl group of said alkylamino group capable of being substituted by a member selected from the group consisting of a hydroxy group, a dialkylamino group of from 2 to 8 carbon atoms and an alkoxy group of from 1 to 4 carbon atoms, an arylamino group, said arylamino group capable of being substituted with a member selected from the group consisting of an alkyl group of from 1 to 4 carbon atoms, an alkoxy group of from 1 to 4 carbon atoms, a hydroxy group and a halogen atom, an alkoxyl group of from 1 to 6 carbon atoms, an aryloxy group, said aryloxy group capable of being substituted with a member selected from the group consisting of an alkyl group of from 1 to 4 carbon atoms, an alkoxy group of from 1 to 4 carbon atoms, a hydroxy group, and a halogen atom, an alkyl group of from 1 to 6 carbon atoms, an aryl group, said aryl group capable of being substituted with a member selected from the group consisting of an alkyl group of from 1 to 4 carbon atoms, an alkoxy group of from 1 to 4 carbon atoms, a hydroxy group, and a halogen atom, or a halogen atom, said compound represented by the above described formula containing no more than one group which is active to gelatin, with the proviso that if R.sub.1, R.sub.2 or R.sub.3 is a halogen atom, no more than one of said R.sub.1, R.sub.2 and R.sub.3 can be a halogen atom.
