Abstract

1329077 Pressure-sensitive recording sheets FUJI PHOTO FILM CO Ltd 12 Aug 1971 [17 Aug 1970] 38013/71 Heading D2B [Also in Division C4] Pressure-sensitive recording sheets are coated with a colour-former solution comprising a known colour-former dissolved in a solvent comprising at least one alkyl-naphthalene of formula: wherein R and R' are each C 1 -C 18 alkyl, p and q are each 0-4 and p+q=1-4 (see Division C4-5). A sheet as above may be used in conjunction with a "lower" sheet coated with a colour-developer. Alternatively, a "middle" sheet may be used in which the colour-former and colour-developer compositions are on opposing surfaces of the same sheet, or a single recording sheet may be formed with the two compositions on the same surface of the sheet. The solutions may be applied in microcapsular form. The alkylnaphthalene may be used with conventional solvents, e.g. natural and synthetic oils and chlorinated compounds. [GB1329077A]
