Abstract

PURPOSE: To enhance the sensitivity of a direct positive silver halide emulsion without exerting unfavorable influence on other photographic characteristics by applying the emulsion to a support having a polyolefin surface layer immediately after corona discharge treatment.
CONSTITUTION: A direct positive silver halide emulsion is applied to the surface of the support of a photographic material within 2min after the corona discharge treatment of the support surface, and it is dried. The support has a coat of polyethylene or other polyolefin or is made of polyolefin. Thus, the sensitivity alone of the emulsion can be enhanced with very little influence on other photographic characteristics such as r-value and Dmax.
