ABSTRACT:
An electrostatic recording material having a good workability and a very good recording characteristic is prepared by coating such a base sheet as paper, plastic film, metal plate, etc. with an aqueous dispersion comprising (A) 100 parts by weight of at least one water-insoluble polymer comprising at least one monomer selected from ethylenic monomers and conjugated diolefinic monomers, and (B) 1-200 parts by weight of at least one water-soluble salt of polymer containing carboxyl groups by means of an air knife coater, roll coater, etc. It is possible to use not more than 6 parts by weight of the heretofore well-known nonionic emulsifier and/or the well-known anionic emulsifier together with said component.
