IPC: B41M5/26
Filed: 1990-01-31
Abstract: PURPOSE:To form a good electrostatic latent image on a photosensitive body and to record a good image on plain paper by obtaining a reversible thermal medium low in light transmissivity by providing a light absorbing layer composed of a phthalocyanine compound on a support. CONSTITUTION:A light absorbing layer 22 constituted of a metal free phthalocyanine compound or a phthalocyanine compound containing either one of elements of the Group I-the Group V is formed on a polymer film 21 and a thermal layer 3 composed of a reversible thermal material is formed thereon and a protective layer 24 is further formed thereon. The phthalocyanine compound has photosensitivity within a visible light region and the wavelength dependence of the photosensitivity thereof almost coincides with that of light absorptivity. Therefore, when the phthalocyanine compound is used in the light absorbing layer, light having a wavelength high in photosensitivity is absorbed by the light absorbing layer and, therefore, the light having a wavelength high in photosensitivity applied to a photosensitive body is reduced. As a result, when the thermal layer, that is, the reversible thermal medium is placed in an opaque state, the charge applied on the photosensitive body is held.
