Pressure-sensitive color-developer material |
(57) A color-developer material for use in pressure-sensitive recording is disclosed which
is capable of developing a colored image upon reactive contact with substantially
colorless color-formers, and comprises a salicylic acid derivative and/or a multivalent
metal salt thereof, dispersed in a petroleum resin. This combination provides enhanced
intensity of the developed image and increased speed of the imaging performance.
