Abstract

Improvements in the preparation of a pressure sensitive recording paper, characterized in that a color former, capable of forming a distinguishable color, is dissolved when reacted with a color developer in a solvent selected from the group consisting of a alkylated biphenyl, having 1 to 4 alkyl groups and an alkylated terphenyl, having 1 to 6 alkyl groups, said alkyl groups having 1 to 12 carbon atoms, microencapsulating the solution and then coating the microcapsules on a support.
