ABSTRACT:
A photosensitive element which comprises a substrate having a release surface; a photosensitive layer having a photosensitizer, pigment, and mixture of binders with different solubility characteristics; and an adhesive layer coated directly on the photosensitive layer. The adhesive solution dissolves one of the resins in the photosensitive layer but does not dissolve the photosensitizer and the resin used to bind the pigment. During overcoating of the adhesive on the photosensitive layer, an increasing gradient of the soluble resin towards the adhesive layer and a decreasing gradient of the photosensitizer and nonsoluble resin is formed.
