PURPOSE: To obtain a photo-recording element capable of highly reliable high- density recording by a method in which at least one of A-layer, B-layer, and a light absorptive layer is made up of the monomolecular film or its laminate film of constituent substances and a protective layer is further provided.
CONSTITUTION: A laminate consisting of A-layer 2 of a color-forming compound, B-layer 4 of an auxochromic compound and a light absorptive layer 3 of a light absorptive substance which is provided between the A- and B-layers 2 and 4 is provided through the B-layer 4 on a substrate 1, and a protective layer 30 is formed on the A-layer 2. In such a constitution, at least one of the A- and B-layers and the layer 2, 4 and 3 is made up of the monomolecular film or its laminate film of constituent substances, and the other layer is formed of deposite films. By irradiation of infrared rays, the leuco dye of the a-layer is contacted with the phenolic compound of the B-layer and a chromogenic reaction is advanced to form color points at given positions. Information can thus be recorded.
