摘要：
The present invention provides a photographic material comprising on a support photosensitive silver halide particles, and substantially light insensitive silver salt particles having a speed at least a factor 10 less under the same conditions of exposure and development of said photosensitive silver halide particles than said photosensitive silver halide particles and a releasing compound of formula (I) or (II) as specified in the claims capable of image-wise releasing sulphide or a sulphide under conditions for image-wise development of said photosensitive silver halide particles to silver. The present invention further provides a method for obtaining an image and a lithographic printing plate with said photographic material.
