ABSTRACT:
A hydrophobic synthetic resin is used to partially or completely replace the hydrophilic colloid conventionally used in silver halide emulsions to obtain a radiation sensitive composition useful in the manufacture of radiation sensitive plates for use in printing plate production by image-wise exposure, tanning development, and washing. The synthetic resin includes a plurality of primary amino groups and optionally acidic groups and is soluble in aqueous or semi-aqueous alkaline solution.
