Abstract

1,273,454. Pressure sensitive copying paper. FUJI PHOTO FILM CO. Ltd. 8 Oct., 1970 [8 Oct., 1969], No. 47923/70. Heading D2B. [Also in Divisions C2 and C4] Fluorane compounds of the general formula: wherein each R is C 1 -C 5 alkyl, each Ar is an aryl group, X is halogen and n is an integer from 1 to 4 are used in copying papers and form a colour on contact with an electron acceptor material. The copying papers may comprise sheets coated with microcapsules containing the fluorane compounds in an oily solvent.
