Color light-sensitive material with infrared dye releaser
摘要:
A silver halide color light-sensitive material comprising a support having thereon at least a silver halide and an infrared-absorbing image-forming compound represented by formula (I):(Dye --X).sub.q --Y (I)wherein Dye represents an infrared-absorbing dye group or an infrared-absorbing dye precursor group derived from a compound represented by formula (II)A, (II)B or (II)C; X represents a chemical bond or a connecting group; Y represents a group capable of making a difference in the diffusibility of the dye component of said compound represented by formula (I) between before and after the reaction with the silver halide having a latent image in correspondence or counter correspondence to the silver halide; having a latent image and q represents an integer 1 or 2, and when q is 2, the two (Dye-X) groups may be the same or different: ##STR1## wherein R.sup.1A and R.sup.2A may be the same or different and each represents a substituent as defined in the specification; and Ar represents an aryl group or a heterocyclic group, which substituents may be further substituted by other substituents; ##STR2## wherein R.sup.1B has the same meaning as R.sup.1A ; R.sup.2B represents a substituent selected from the group consisting of an alkyl group, an aryl group, a heterocyclic group, an alkoxy group and an amino group; and R.sup.3B represents a substituent as defined in the specification; ##STR3## wherein R.sup.1C and R.sup.2C may be the same or different and each has the same meaning as R.sup.1A ; and m and n each represents an integer of from 0 to 4, with the proviso that if m and n each is 2 to 4, the plurality of substituents may be the same or different, these substituents may be further substituted by other substituents;Dye and X may be bonded to each other in any position in formulas (II)A, (II)B and (II)C.
