Abstract

1356128 Pressure-sensitive recording sheet FUJI PHOTO FILM CO Ltd 12 Nov 1971 [13 Nov 1970] 52766/71 Heading D2B [Also in Division C4] A pressure-sensitive recording sheet comprises paper coated with microcapsules containing a colour-former composition comprising an organic solvent solution of a colourformer and a hydrogenated quinoline compound. The latter may be used in an amount 10-500% by wt. of the colour-former as a stabiliser therefor. Conventional colour-formers and solvents are listed. The sheet can be used in conjunction with a second sheet coated with a solid acid substance as colour-developer.
