Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
211 words
A color light-sensitive material which comprises a support having provided thereon at least a light-sensitive silver halide and an image-forming compound represented by general formula (I) (Dye--X).sub.q Y (I) wherein X represents a single chemical bond or a divalent linking group, Y represents a group having the properties of causing differences in diffusibility of the dye moiety before and after reaction with the silver halide corresponding directly or inversely to the silver halide which is in imagewise latent image form, q represents 1 or 2, and, when q represents 2, the two Dye-X groups are the same or different, and Dye represents a yellow dye group or dye group precursor represented by formula (II) ##STR36## wherein R 1 represents a cyano group or a substituent group selected from among the groups represented by formulae (A), ##STR37## wherein R 11 represents a substituent selected from among substituted or unsubstituted aryl and heterocyclic groups, and R 2 represents an electron attractive group having a Hammett para-sigma value of from 0 to +1.0, n represents an integer of 1 to 4 and, when n represents 2 to 4, the R 2 groups are the same or different, and Dye and X are bound to each other at either R 11 or R 2 .
Claim 2
Dependent Claim
211 words
A color light-sensitive material which comprises a support having provided thereon at least a light-sensitive silver halide and an image-forming compound represented by general formula (I) (Dye--X).sub.q Y (I) wherein X represents a single chemical bond or a divalent linking group, Y represents a group having the properties of causing differences in diffusibility of the dye moiety before and after reaction with the silver halide corresponding directly or inversely to the silver halide which is in imagewise latent image form, q represents 1 or 2, and, when q represents 2, the two Dye-X groups are the same or different, and Dye represents a yellow dye group or dye group precursor represented by formula (II) ##STR36## wherein R 1 represents a cyano group or a substituent group selected from among the groups represented by formulae (A), ##STR37## wherein R 11 represents a substituent selected from among substituted or unsubstituted aryl and heterocyclic groups, and R 2 represents an electron attractive group having a Hammett para-sigma value of from 0 to +1.0, n represents an integer of 1 to 4 and, when n represents 2 to 4, the R 2 groups are the same or different, and Dye and X are bound to each other at either R 11 or R 2 .
