Title:
SILVER HALIDE COLOR PHOTOGRAPHIC SENSITIVE MATERIAL IMAGE FORMING METHOD AND PHOTOGRAPHIC TRANSPARENT CELLULOSE ESTER FILM BASE
Document Type and Number:
Japanese Patent JP2000284430
Kind Code:
A
Abstract:

To make it possible to lessen the influence of the temperature fluctuation of a negative film at the time of printing, to lessen the influence of a pH fluctuation of a color development processing liquid, to improve concentration stability and to obtain a print of stable color tones by incorporating specific compounds into photograph constitution layers and incorporating specific color developing agents into a color development processing liquid.

This photographic sensitive material has the photograph constitution layers consisting of red, green and blue photosensitive layers and a nonphotosensitive layer on one side of a base and contains the compounds expressed by formula I: RaOOC(CH2)mCOORb, formula II: RcOOC(CnH2n-2)mCOORd, etc. The color development processing liquid contains the color developing agents expressed by formula III, formula IV, etc. In the formulas I and II, Ra to Rd denote 4-10C straight chain or branched alkyl groups; m and n denote an integer from 2 to 10. In the formulas III and IV, R1 to R6, R9 to R12 denote hydrogen atoms, substituents; R7 denotes an alkyl group; R8 and R13 denote substituents and m and n denote an integer from 0 to 3.
