    摘要: Remarkably high inter-image and edge effects are obtained when DIR-Couplers corresponding to Formula I are added to multilayered color photographic recording materials, in particular to green sensitive or red sensitive layers. The sharpness and color reproduction may thereby be improved. ##STR1## R.sup.1 and R.sup.2 denote alkyl or an aromatic group, R.sup.3 denotes H, alkyl or acylamino,R.sup.4 denotes H or alkylR.sup.5 denotes alkyl, alkinyl, aryl, acyloxy, carbamoyl or a cyclic imido group andn has the value 0 or 1and the total number of carbon atoms in R.sup.3, R.sup.4 and R.sup.5 is greater than 3 but not greater than 11.

    摘要: Pyrimidone or thiopyrimidone benzothiazole monomethine cyanines are valuable spectral sensitizers for sensitizing negative silver halide emulsions in the blue region of the spectrum. In contrast to other known monomethine cyanines they have little or no desensitizing effect in the range of inherent sensitivity.
