Abstract

863,366. Photothermographic processes. MINNESOTA MINING & MANUFACTURING CO. March 29, 1957 [April 2, 1956], No. 10377/57. Drawings to Specification. Class 98(2) A graphic original is copied on to a heatsensitive copy sheet which is absorbent of radiant energy by placing the original on top of the heat-sensitive copy sheet and irradiating it with radiant energy to provide a transmitted radiant energy pattern which is absorbed by the copy sheet to give a visible image. The opaque parts of the original absorb the radiant energy and do not conduct it to the copy sheet, but it may be desirable to place an additional barrier such as silk bolting cloth between the original and copy sheet to prevent such conduction. The heat-sensitive layer may comprise ferric stearate and gallic acid in an ethyl cellulose binder, preferably together with pigments such as titanium dioxide or carbon black, or it.may comprise gum guaiac and cerium stearate in an ethyl cellulose binder together with pigmerits as desired. Alternatively, the copy paper may comprise a dark or coloured substrata obscured with a layer of normally transparent fusible material e.g. a waxy material, as is described in Specification 673,244.
