Abstract

Improvements in the manufacture of pressure-sensitive copier sheets, characterized in that each sheet comprises a support that has as its coating a microcapsule layer, said microcapsules containing a colorless compound, dissolved in oil and represented by the following general formula, **(See formula)** wherein r1 and R2 are each an alkyl group, having 1 to 5 carbon atoms, said compound being capable of forming color dye when contacted with solid acid that accepts electrons.
