Abstract
A color photographic recording material comprising a support and at least one photosensitive silver halide emulsion layer, with which a yellow coupler of the pivaloyl or benzoyl acetanilide type dissolved in a polymeric ester of aromatic or aliphatic dicarboxylic acids is associated, is distinguished by greater color purity and better dark-fading stability.
Claims4
A color reversal photographic for exposure and development by reversal color development comprising a support and at least one photosensitive silver halide emulsion layer with which a yellow coupler dissolved in an oil former is associated, characterized in that the yellow coupler corresponds to the following formula
- in which
- R.sub.1 represents tert.-butyl or optionally substituted phenyl,
- R.sub.2 represents hydrogen or a releasable group,
- R.sub.3 represents hydrogen, alkoxy or halogen,
- R.sub.4 represents hydrogen, alkoxy or dialkylaminosulfonyl and
- R.sub.5 represents hydrogen, alkoxy or a ballast group,
- the coupler molecule containing at least one ballast group, and in that the oil former consists essentially of a polymeric ester of aromatic dicarboxylic acid.
