Abstract

1352597 Pressure-sensitive recording paper FUJI PHOTO FILM CO Ltd 23 Aug 1971 [24 Aug 1970] 39499/71 Heading D2B [Also in Division C4] Pressure-sensitive recording paper is coated with a colour-forming solution comprising a conventional colour-former dissolved in a solvent comprising at least one alkylated biphenyl having 1-4 substituent alkyl groups containing a total of not more than 24 carbon atoms, or at least one alkylated terphenyl having 1-6 substituent alkyl groups totalling not more than 26 carbon atoms, each alkyl having 1-12 carbon atoms. Other solvents, e.g. kerosene, naphtha, paraffin oil, chlorinated paraffin, chlorinated diphenyl or a vegetable oil, may be present. Numerous colour-formers are listed. Conventional developers therefor include acid clays and phenolic resins. The solution may be formed into microcapsules as known and coated by the air-knife or roll coating method on to a paper sheet.
