Abstract

1,023,004. Heat-sensitive copying material. R. KORESKA, [trading as W. KORESKA]. Oct. 18, 1962 [Dec. 23, 1961], No. 39435/62. Heading G2C. A heat-sensitive copying material comprises two contiguous layers coated on a support sheet which may be transparent, each layer comprising a chemical reagent, the reagent of one layer being capable of reacting with the reagent of the other layer to produce a colour, at least the major part of one of the layers melting at a temperature of not greater than 150‹C. Specified combinations of chemical reagents are ferric stearate/pyrogallol, ferric stearate/gallic acid and ferric sulphate/gallic acid and diazonium salts and their coupling agents. The chemical reagents may be contained in binders having melting points at or below that of the reagent e.g. hard paraffin, polystyrol, saponified Montan wax or polystyrene or binders such as ethyl cellulose together with kaolin which produces a white coating when air blown. The outer layer may be coloured e.g. with TiO 2 . A transparent protective layer of acetyl cellulose may be applied.
