Abstract

A new linear copolymer contains 5-60 mole % of units of formula (I), 30-50 mole % of units of formula (II), 0-60 mole % of units of formula (III), and 0-60 mole % of units of formula (IV). The copolymer has a wt. average mol wt. of 500-30,000 and units (I), (III) or (IV) are coupled to different units (I), (III) and (IV) via the unit, (II). Where R1-R3 = 1-4C alkyl; R4 = (cyclo)alkyl, aralkyl or phenyl. The copolymer may be in the form of a multivalent metal salt, the metal forming the salt between the carboxyl gps. in the same or different copolymer molecules. Also claimed is (i) a colour developing agent for pressure-sensitive copying paper, which contains the multivalent metal-modified copolymer and (ii) the developing agent provided evenly on one side of a developer sheet.
