Electrographic recording material

An electrographic recording material comprising a conductive sheet support coated on at least one side with an electrically insulating layer comprising an intimate blend of a polymeric binder and from 200 to 1000 parts by weight of a finely divided non-photoconductive pigment per 100 parts by weight of the polymeric binder;

• wherein the polymeric binder comprises a major proportion of a low molecular weight interpolymer and a minor proportion of a high molecular weight interpolymer;
• wherein the low molecular weight interpolymer comprises from about 40 to about 85 parts by weight of monovinyl aromatic monomer units and from about 15 to about 60 parts by weight of units of a C.sub.3 -C.sub.7 allylic alcohol and of a C.sub.3 -C.sub.7 allylic alcohol ester of a monocarboxylic acid, the mol ratio of monovinyl aromatic units to allylic alcohol and allylic ester units being about 3:1 or less, the mol ratio of allylic ester units to allylic alcohol units being in the range of 0 to about 10, the number average molecular weight of the interpolymer being in the range of about 700 to about 5000 and the glass temperature of the interpolymer being at least about 30.degree. C.;
• wherein the high molecular weight interpolymer has a number average molecular weight in the range of about 5,000 to about 100,000;
• and wherein the weight ratio of low molecular weight interpolymer to high molecular weight interpolymer is in the range of about 99:1 to about 70:30.
