ABSTRACT:
A chromogenic composition for use in pressure-sensitive record material comprises chromogenic material in an ester vehicle. The ester may be mono-, di- or tri-functional and is of a non-aromatic mono-carboxylic acid having a straight or branched hydrocarbon chain with at least three carbon atoms in the chain. Suitable esters include fatty acid esters such as cocoates, isostearates, myristates, and palmitates and wax esters such as alkyl-branched esters of an aliphatic carboxylic acid and an aliphatic alcohol.
