ABSTRACT:
The negative working image recording image recording material of the present invention is a negative working image recording material comprising (A) a compound which acts as a cross-linking agent in the presence of an acid, (B) a binder polymer, (C) a compound which generates an acid by the action of heat and (D) an infrared absorber, wherein (A) the compound which acts as a cross-linking agent in the presence of an acid is a phenol derivative represented by the following general formula (I) or (II) wherein each of the groups is defined and wherein (B) the binder polymer is a polymer having in the side chain an aromatic hydrocarbon ring having directly linked thereto a hydroxyl group or an alkoxy group if (A) is a phenol derivative represented by the general formula (I), but (B) the binder polymer is a polymer having in the main chain or the side chain an aromatic hydrocarbon ring having directly linked thereto a hydroxyl group or an alkoxy group if (A) is a phenol derivative represented by the general formula (II). ##STR1##
