Abstract
1337757 Thermographic materials COLUMBIA RIBBON & CARBON MFG CO Inc 5 Oct 1971 [19 Oct 1970] 46259/71 Heading G2C A thermographic material comprises a transparent polymeric support, a first layer containing an acid-sensitive dye-precurser and a binder which is either (i) a vinyl chloride homo- or co-polymer or a mixture of 2 or more thereof or a mixture of such a homo- and/or co-polymer with another polymer soluble in a common solvent or (ii) a vinyl-idene chloride homo- or copolymer mixed with 25-95 per cent by weight of the mixture, a polymer soluble in a common solvent and a second layer containing a vaporizable aromatic acid in a binder other than nitrocellulose which is not soluble in, nor a solvent for the binder of the first layer, the layers being coated in either order. Specified binders for the second layer are polyvinyl butyral, cellulose acetate butyrate and nylon.. In the example, a polyester support is coated with a layer containing acrylonitride/ vinylidene chloride copolymer and acrylonitride/ styrene copolymer as binder and as dye precursers, N[ -bis (p-dimethyl-amino phenyl) methyl] - morpholine and compounds of formulae:- and then with a layer of 5-bromosalicylic acid, polyvinyl butyral and cellulose acetatebutyrate is alcohol which is not a solvent for the first layer The exposed material may be used as a projection. transparency.
