ABSTRACT:
Disclosed are polyesters and polycarbonates of the formulae ##STR1## wherein X is an anion with weak nucleophilicity, A, B, and C represent the number of repeat monomer units, wherein C may be zero, R is selected from the group consisting of hydrocarbon groups and alkylene ether groups, and R" is selected from the group consisting of hydrogen, nitro, amide, halide, trimethylsilyl, alkyl groups, and alkoxy groups. The compounds are suitable for use as polymerization initiators, particularly in applications wherein curable liquids are cured to solids. One specific embodiment of the invention is directed to a curable liquid developer composition comprising a colorant, a polymeric compound of the above formula, and a substantial amount of a curable liquid vehicle having a viscosity of no more than about 500 centipoise and a resistivity of no less than about 10.sup.8 ohm-cm.
