摘要：The sensitization of tabular grain silver halide emulsions is greatly enhanced bythe synergistic use of a particular zeromethine dye combined with a tetraazaindenecompound. Chemical sensitization with sulfur compounds is also enhanced by thiscombination of ingredients which can not only yield reduced dye stain to the finishedproduct but which can improve both spectral and chemical sensitometry.
