Abstract

1370081 Pressure-sensitive record sheets WIGGINS TEAPE RESEARCH & DEVELOPMENT Ltd 2 Jan 1973 [31 Jan 1972] 4472/ 72 Heading D2B [Also in Division B2] A pressure-sensitive record sheet comprising a base sheet coated with microcapsules containing a chromogenic material, a protective material for protecting the material against accidental rupture, and a binder material is made (a) by first coating the base sheet with an aqueous coating mix including a rewettable binder material and a protective material, (b) drying the first coating, (c) rewetting the dried first coating, (d) applying a coating of microcapsules to the rewetted first coating, and (e) drying again. Steps (c) and (d) may be carried out simultaneously. The microcapsules may be applied from aqueous dispersion or in a dry form. The binder material may be dextrine, polyvinyl alcohol, or a mixture thereof. The protective material may be cellulose fibres, granular polymeric material, or starch granules. A coreactant material capable of reacting with the chromogenic material may be carried on the same or different base sheet.
