Abstract

Improvements in the manufacture of copier paper, sensitive to pressure, characterized in that the paper consists of a support, which has a layer of microcapsules coated on it, containing at least one fluorane derivative, represented by the following general formula, **(See formula)** wherein R1 and R2 each represent an alkyl group, having 1 to 5 carbon atoms, R3 represents a hydrogen atom, an alkyl group having 1 to 5 carbon atoms, or a benzyl group, and R4 represents an aryl group .
