发明名称 |
A silver salt diffusion transfer material and method for making an image therewith. |
摘要 |
The present invention provides a photographic material comprising on a support an image-receiving layer containing physical development nuclei, a photosensitive silver halide emulsion layer and a substantially light insensitive layer containing silver salt characterized in that said photosensitive silver halide emulsion layer contains silver halide particles having an average diameter of at least 0.6 mu m, said photosensitive silver halide emulsion layer being located between said image-receiving layer and said substantially light insensitive layer and said substantially light insensitive layer having a speed of at least a factor 10 less than said photosensitive silver halide emulsion layer. The present invention also provides a method for making an image therewith. The photographic material of the present invention is of high speed and can yield direct positive image with a low density in the non-image areas.
