Silver halide photographic material

A method for obtaining an image according to the DTR-process comprising the steps of:

• information-wise exposing a photographic material comprising on a support (i) photosensitive silver halide particles, (ii) substantially light insensitive silver salt particles having a speed at least a factor 10 less than said photosensitive silver halide particles under the same conditions of exposure and development of said photosensitive silver halide particles, (iii) a releasing compound capable of image-wise releasing under the conditions for image-wise development of said photosensitive silver halide to silver a chemical sensitizer, said chemical sensitizer rendering said substantially light insensitive silver salt particles developable and (iv) a layer of physical development nuclei
• and developing said information-wise exposed photographic material in an alkaline processing solution in the presence of (a) developing agent(s) and containing (a) silver halide solvent(s).

A method for preparing a lithographic printing plate according to the DTR-process comprising the steps of:

• information-wise exposing a lithographic printing plate precursor comprising on a support (i) a photosensitive silver halide, (ii) a substantially light insensitive silver salt having a speed at least a factor 10 less than said photosensitive silver halide particles under the same conditions of exposure and development of said photosensitive silver halide particles and (iii) a releasing compound capable of image-wise releasing under the conditions for image-wise development of said photosensitive silver halide to silver a chemical sensitizer, said chemical sensitizer rendering said substantially light insensitive silver salt particles developable and (iv) a layer of physical development nuclei as an outermost layer on the photosensitive side of said support,
• and developing said information-wise exposed photographic material in an alkaline processing solution in the presence of (a) developing agent(s) and containing (a) silver halide solvent(s).

A method for preparing ,a lithographic printing plate according to the DTR-process comprising the steps of:

• information-wise exposing a lithographic printing plate precursor comprising on a hydrophilic support provided with an image receiving surface or image receiving layer containing physical development nuclei (i) a photosensitive silver halide, (ii) a substantially light insensitive silver salt having a speed at least a factor 10 less than said photosensitive silver halide particles under the same conditions of exposure and development of said photosensitive silver halide particles and (iii) a releasing compound capable of image-wise releasing under the conditions for image-wise development of said photosensitive silver halide to silver a chemical sensitizer, said chemical sensitizer rendering said substantially light insensitive silver salt particles developable,
• developing said information-wise exposed photographic material in an alkaline processing solution in the presence of (a) developing agent(s) and containing (a) silver halide solvent(s) to obtain a silver image on said image receiving surface or in said image receiving layer,
• and removing all layers above said silver image to expose said silver image by means of rinsing with water.
