ABSTRACT:
An electrographic recording material comprising a conductive sheet support coated with an electrically insulating layer comprising an intimate blend of a polymeric binder and from about 200 to about 1000 parts of an inert finely divided pigment per 100 parts by weight of polymeric binder. The binder contains a major proportion of a low molecular weight interpolymer comprising a monovinyl aromatic monomer, a C.sub.3 -C.sub.7 allylic alcohol and optionally a monocarboxylic acid ester of a C.sub.3 -C.sub.7 allylic alcohol, and a minor proportion of high molecular weight interpolymer.
