Abstract
997, 361. Thermographic copying material and process. MINNESOTA MINING & MANUFACTURING CO. Jan. 3,1962 [Jan. 3, 1961, No. 300/62. Heading G2C. A copy sheet or copysheet combination, which forms a visible image when heated but can be desensitized by exposure to ultra-violet radiation, contains (1) a normally solid salt of a noble metal, e.g. silver behenate, and (2) an alpha-naphthol having an electron-donor substituent in the same aromatic ring as the hydroxy group, e.g.4-methoxy-1- naphthol. Copies may be made by placing an original in contact with the copy sheet or combination irradiating with infra-red while in contact, and subsequently desensitizing the copy by exposure to ultra-violet, or by exposing a copy sheet to ultraviolet through a transparent original bearing opaque markings, and subsequently heating to develop colour in the areas not so desensitized. The two reagents may be disposed in a single layer, in separate layers on a single carrier, or in separate layers on separate carriers. They may be dispersed in a thin film of a resinous or polymeric film-forming binder in the form of a selfsustaining film, or as a coating on a backing of film, paper or the like. The Specification includes lists of suitable naphthols and binders. The sheets may also include pigments, fillers, plasticizers, dyes, waxes, resins and toning agents. Specification 997,362 is referred to.
