Abstract

1,219,166. Pressure-sensitive copying sheet. FUJI SHASHIN FILM K.K. and HODOGAYA KAGAKU GOGYO K.K. 30 Oct., 1968 [31 Oct., 1967], No. 51490/68. Heading D2B. [Also in Divisions C2] Colour-former paper comprises a support bearing a layer of microcapsules containing at least one 3-amino-6-chlorofluorone compound of formula: where R represents a hydrogen atom, an alkyl group of 1 to 3 carbon atoms, an aryl group or an aralkyl group. The colour-former may be 3-amino-3-methylamino-, 3-ethylamino-, 3- phenylamino-, 3-benzylamino-, 3-m-tolylamino- or 3-m-xylylamino-6-chlorofluorone. These give colours ranging from yellow-orange to purple when contacted with an acid clay. The capsules may also contain a conventional blue colourformer. The microcapsules may be used in a one-sheet or a two-sheet system.
