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-isoluble polymer prepared from at least one monomer selected from the group consisting of (1) conjugated diolefinic monomers and (2) ethylenic monomers selected from the group consisting of linear olefins, branched olefins, aromatic vinyl compounds, vinyl cyanide compounds, alkyl acrylates, alkyl methacrylates, vinyl ethers, and vinyl halides, and (B) 1 to 200 parts by weight of at least one water-soluble salt selected from the group consisting of an ammonium salt and organic amine salt of a copolymer selected from the group consisting of (1) copolymers of unsaturated carboxylic acids and ethylenic monomers selected from the group consisting of linear olefins, branched olefins, aromatic vinyl compounds, vinyl cyanide compounds, alkyl acrylates, alkyl methacrylates, vinyl halides, acrylamide, methacyrlamide, and vinyl ethers, (2) copolymers of conjugated diolefinic monomers and unsaturated carboxylic acids, and (3) copolymers of conjugated diolefinic monomers, unsaturated carboxylic acids and ethylenic monomers selected from the group consisting of linear olefins, branched olefins, aromatic vinyl compounds, vinyl cyanide compounds, alkyl acrylates, alkyl methacrylates, vinyl halides, acrylamide, methacrylamide, and vinyl ethers, said water soluble salt of the copolymer containing 8 to 50 mole percent of 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 conventional nonionic emulsifier and/or a conventional anionic emulsifier together with said components.
