Anodized aluminum photographic plates with silver bromide in pores of oxide layer, and process of manufacture thereof

摘要

An improved photographic element having high photosensitivity, which element comprises an anodized aluminum plate as a support having silver halide adsorbed in the pores of the oxide layer on the surface of said plate. The improvement comprises adding aqueous ammonia to a solution of silver nitrate used in forming said silver halide, the amount of aqueous ammonia being sufficient to raise the photosensitivity of the element.
