ABSTRACT:
Disclosed is a non-crosslinked copolymer composition, for use in developing an electrophotographic latent image, comprising a styrenic compound, methylmethacrylate, and a soft comonomer. The soft comonomer has the general formula: ##STR1## wherein R.sub.1 is a hydrogen or methyl group, and R.sub.2 may be a ethyl, butyl, n-butyl, iso-butyl, ethyl-hexyl, propyl, octyl, lauryl or stearyl group. The softening range of this copolymer is 2 to 15 Celcius temperature units broader than comparable non-crosslinked copolymers which do not contain methyl methacrylate.
