摘要: An electrographic recording material comprising a conductive paper support coated with an electrically insulating layer comprising an intimate blend of a polymeric binder and up to 500 parts of an inert finely divided pigment per 100 parts by weight of polymeric binder. The binder comprises poly(vinyl acetal) and an alkoxymethyl polyaminotriazine. The electrographic recording material exhibits improved resistance to curl when it is exposed to variable humidity conditions.

摘要: Coating compositions comprising intimate blends of a polyvinyl acetal, an alkoxymethyl polyaminotriazine and an oligomeric polystyrene or poly(.alpha.-methylstyrene). The coating compositions may contain up to 500 parts by weight of an inert non-photoconductive pigment per 100 parts by weight of polymer blend. The compositions are useful for the preparation of electrographic recording media which possess improved resistance to curl under variable conditions of humidity.
