ABSTRACT:
A coating material for a pressure-sensitive recording sheet comprises both microcapsules A and microcapsules B, wherein the microcapsules A contains a solvent S.sub.1 which dissolves a colorless dye for a pressure-sensitive recording sheet, and the microcapsules B contains a dye-free solvent S.sub.2 which has no ability of dissolving dye and which has a lower boiling point than the solvent S.sub.1. The pressure-sensitive recording sheet using this coating material provides an improved thermal smudge without the deterioration of the image density, etc.
