Element with gelatin anti-stress layer for making printing plate according to the silver salt diffusion transfer process

摘要

The present invention provides an imaging element comprising in the order given on a hydrophilic surface of a support (i) an image receiving layer containing physical development nuclei, (ii) a photosensitive layer containing a silver halide emulsion being in water permeable relationship with said image receiving layer and (iii) an antistress composition in water permeable relationship with said image receiving layer, said antistress composition comprising unhardened gelatin in an amount ranging from 0.60 to 1.75 g/m2, characterized in that at least 50% by weight of said unhardened gelatin belongs to one or more gelatin species whereof a 10% by weight aqueous solution at 36 DEG C. and pH 6 has a viscosity lower than 35 mPa.s at a shearing rate of 1000 s-1.
