摘要:
The present invention relates to polymethine spectral sensitising dyes comprising at least one intracyclic thioether function macrocycle.These special sensitising dyes may be used in silver halide photographic products.These spectral sensitising dyes improve the sensitivity of the photographic products whilst reducing the residual dye stain.
