Abstract

1296477 Colour-reactive copying sheets FUJI PHOTO FILM CO Ltd 24 July 1970 [29 July 1969] 36059/70 Heading D2B Pressure-sensitive copying paper has a coating of micro-capsules containing a colourless colour-former in solution in a chlorinated straight-chain paraffin. The solvent may also contain chlorinated diphenyl, and the solute may be malachite green lactone, benzoyl-leucomethylene blue, 3, 3-bis-(p-dimethylaminophenyl)-6-dimethylaminophthalide, rhodamine- B-lactam, a 3-dialkyl-amino-7-alkylaminofluorane or 3-methyl-2, 2'-spiro-bi (benzo[f] chromene). The second reagent, an electron-acceptor, may be on the same support sheet or on a separate copy-receiving sheet. [GB1296477A]
