摘要： Spectral properties of dye images produced from low silver halide coverage materials are improved by using dyes which are formed in the magenta, yellow and cyan image dye-forming units. These dyes have certain spectral characteristics, as determined by their unwanted absorptions, in combination with certain silver halide emulsion grain characteristics in each emulsion layer. In particular, reduction of unwanted absorptions can be achieved either with couplers per se which meet these characteristics or by the use of certain high-boiling solvents in the coupler dispersions at preferred levels.
