Abstract
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.
