Abstract:
An image recording material comprising:(a) a compound decomposable by light or heat, and which produces an acid when decomposed thereby; (b) a crosslinking agent that crosslinks in the presence of an acid; (c) a high-polymer compound substantially insoluble in water and substantially soluble in an alkali aqueous solution; and (d) an infrared absorbing agent selected from the group of general formulas consisting of general formula (I) or general formula (II) as follows: â€ƒwherein in general formula (I), M represents a conjugated chain; Gaâˆ’ represents an anionic substituent; Gb represents a neutral substituent; and Xm+ represents a hydrogen ion or a cation of valence m, where m represents an integer from 1 to 6; and in general formula (II), R1 to R4 each independently represent a hydrogen atom, alkyl group, or aryl group; R5 and R6 each independently represent an alkyl group, substituted oxy group, or halogen atom; n and m each independently represent an integer from 0 to 4; either R1 and R2, or R3 and R4, may bond to form a ring, or R1 and/or R2 may bond with R5, or R3 and/or R4 may bond with R6 to form a ring, and, furthermore, either R5's may bond to form a ring or R6's may bond to form a ring; Z1 and Z2 are each independently a hydrogen atom, alkyl group, or aryl group, and at least one of Z1 and Z2 represents either a hydrogen atom or an alkyl group; Q is a trimethine group or pentamethine group that may have a substituent, and may form a ring structure together with a bivalent organic group; and Xâˆ’ represents a counter-anion.
