Abstract

1,260,593. Thermography. FUJI PHOTO FILM CO. Ltd. May 26, 1970 [May 26, 1969], No. 25302/70. Heading G2C. Heat-sensitive copying materials comprise (a) a 2, 2'-spirobi (benzo [f] chromene) (in which the 3 and/or 3' positions are optionally substituted by 1-8C alkyl, carboxylic acid esto, aralkyl or C 6 H 5 ; (b) a solid acid of formula: R-SO 3 H (in which R is amino, C 2-18 amino alkyl in which the amino group is optionally substituted, 10-20 C alkyl or alkoxy, carboxy-substituted 6-18C alkyl, optionally substituted aralkyl, or an aryl group which is optionally substituted and/or fused to a heterocyclic ring, and (c) a substance which melts at 50-80‹ C. is substantially colourless below 50‹C, and can dissolve (a) and (b) when fused. The materials form a coloured image on heating and may additionally contain a binder and/or an opacifying agent. The components may be in the same sheet or on adjacent surfaces of superposed sheets.
