Photosensitive Ionomer. VIII. Photosensitive Copper (I and II) Carboxylates

Abstract

The photosensitive ionomer is a polymer ionically crosslinked with a metallic ion of variable valence on exposure. By using the ionomer crosslinked with mercurous ions, the authors have already reported the formation of visible, relief, and electrically conductive images and the amplification of a latent image by reducing and oxidizing developments. In the next series of studies it was planned that mercurous ion may be replaced by cuprous or cupric ion, and photosensitivity of various copper (I and II) carboxylates was investigated as the first step. Cupric salts of dibasic carboxylic acids and cuprous carboxylates were found to be comparatively sensitive among them.
