Formation of Organic Pigment Films by Photochemical Reduction of Surfactants Containing an Azobenzene Group
A copper phthalocyanine <B>1</B> thin film and photoimage were formed on a polyester film by irradiation of an aqueous dispersion containing a surfactant with an azobenzene group <B>2a</B>, dispersed <B>1</B>, hydroquinone <B>3</B> and 0.1 M HCl. A spectroscopic study showed that the photochemical reduction of <B>2a</B> with <B>3</B> leads to the deposition of <B>1</B>.
