COLOR PHOTOGRAPHIC RECORDING MATERIAL CONTAINING COLOR COUPLERS WHICH YIELD HEAT-STABLE DYES |
| 摘要 |
A color photographic material containing color couplers which yield heat-stable dyes. A color photographic recording material containing cyan couplers which, during chromogenic development, yield cyan dyes having parameters a and b such that a.(1+b)</=1.5 are suitable for the production of color negatives for multicopy operation in which a plurality of identical copies are successively prepared from the same original. In the above condition: a is the temperature coefficient of the absorption <IMAGE> <IMAGE> and b is the temperature coefficient of the absorption wavelength lambda (T=23 DEG C.) <IMAGE>
