Pressure-sensitive recording material |
摘要 |
A pressure-sensitive recording material is described, comprising an electron-donating color former and an electron-accepting color developer wherein said color developer comprises a mixture of (a) an aromatic carboxylic acid metal salt and (b) a hindered phenol as a combined electron-accepting color developer. The aromatic carboxylic acids should desirably have a hydroxyl group in the ortho or para position to the carboxyl group and preferably is a salicylic acid derivative. The hindered phenols preferably have an alkyl substituent in at least one of the 2 and 6 positions. This pressure-sensitive recording material can provide color images having an excellent fastness to light and solvents.
