Abstract

1401675 Pressure-sensitive record sheets MITSUBISHI PAPER MILLS Ltd 14 Aug 1972 [30 Aug 1971] 37789/72 Heading D2B A method of making a non-carbon copying paper comprises the steps of coating a paper with a coating composition comprising rupturable microcapsules and expandable microspheres of a size less than or substantially equal to that of the said microcapsules and heating the paper to an elevated temperature to cause expansion of the microspheres to a size greater than that of the microcapsules. The rupturable microcapsules may contain an electron-donating colour former in an appropriate solvent. The expandable microspheres may comprise a spherical wall of a vinylidene chloride-acrylic acid ester copolymer containing a hydrocarbon capable of foaming on application of heat. An aqueous oxidised starch composition may be used as a binder in the coating composition. The non-carbon copying paper may be used in transfer sheet assemblies in combination with papers coated with solid acids.
