摘要:
A color photographic element comprises a support bearing at least one photographic silver halide emulsion layer, an image dye-forming coupler, and a coupler (A) capable of forming a compound that is washed out of the photographic element upon processing and capable of releasing a bleach accelerator group, wherein the coupler (A) is represented by the formula:
摘要:
A color photographic element comprises a support and at least one dye image forming layer unit comprising gelatin-peptized radiation-sensitive silver halide grains, a fragmentable electron donating compound; and an electron transfer agent releasing compound.
摘要:
Photographic color developing compositions containing a primary aromatic amino color developing agent and a hydroxylamine compound are stabilised against decomposition of hydroxylamine and formation of sludge by incorporating stabilised chelating compounds of the formula: wherein each R 1 is hydrogen, -CH 2 COOH or each R 2 is hydrogen or -COOH
p is 0 or 1, and X completes a substituted or unsubstituted aromatic nucleus.
The composition may also contain another different chelating agent, e.g. of the aminopolycarboxylic or aminopolyphosphonic acid type.
摘要:
A new photographic coupler comprises a non-diffusible benzoyl-acetanilide represented by the formula: Such a new coupler is useful in a color photographic silver halide element and process to provide higher reactivity.
摘要:
This invention relates to a photothermographic color element containing a mixture of blocked developers in the same emulsion layer, which blocked developers having different onset temperatures. Such a mixture has been found to allow for lower film processing temperatures and/or shorter times of development with respect to the blocked developer having a higher onset temperature. Conversely, improved discrimination can be obtained with respect to the blocked developer having the lower onset temperature.
