Abstract
A silver halide light sensitive photographic element comprising a support bearing at least one cyan image forming hydrophilic colloid layer comprising cyan image dye forming coupler of Formula I and a saturated alcoholic high boiling solvent or mixture of solvents of Formula II: Formula I wherein R1 is an alkyl group, R2 is a ballast group, and X is hydrogen or a coupling-off group; Formula II wherein R3 represents an alkyl group, and R4 and R5 individually represent hydrogen or an alkyl group, or R3 and R4 may be joined to form a cycloalkyl group, provided that the total number of carbon atoms contained in R3, R4, and R5 is at least 10 and that the alcoholic solvent or mixture of solvents of Formula II is liquid at 37° C.

A silver halide light sensitive color photographic print element comprising a support bearing at least one cyan image forming hydrophilic colloid layer comprising cyan image dye forming coupler of Formula I and a saturated alcoholic high boiling solvent or mixture of solvents of Formula II:
- Formula I
- wherein R1 is an alkyl group, R2 is a ballast group, and X is hydrogen or a coupling-off group;
- Formula II
- wherein R3 represents an alkyl group, and R4 and R5 individually represent hydrogen or an alkyl group, or R3 and R4 may be joined to form a cycloalkyl group, provided that the total number of carbon atoms contained in R3, R4, and R5 is at least 10 and that the alcoholic solvent or mixture of solvents of Formula II is liquid at 37° C.
A silver halide light sensitive color photographic color element comprising a support bearing in sequential order on one side thereof at least one yellow image forming hydrophilic colloid layer comprising a blue-sensitive silver halide emulsion and yellow image dye forming coupler, at least one cyan image forming hydrophilic colloid layer comprising red-sensitive silver halide emulsion and cyan image dye forming coupler, and at least one magenta image forming hydrophilic colloid layer comprising green-sensitive silver halide emulsion and magenta image dye forming coupler;
- wherein the cyan image forming hydrophilic colloid layer comprises cyan image dye forming coupler of Formula I and a saturated alcoholic high boiling solvent or mixture of solvents of Formula II:
- Formula I
- wherein R1 is an alkyl group, R2 is a ballast group, and X is hydrogen or a coupling-off group;
- Formula II
- wherein R3 represents an alkyl group, and R4 and R5 individually represent hydrogen or an alkyl group, or R3 and R4 may be joined to form a cycloalkyl group, provided that the total number of carbon atoms contained in R3, R4, and R5 is at least 10 and that the alcoholic solvent or mixture of solvents of Formula II is liquid at 37° C.
