ABSTRACT:
An electrostatic recording material comprising a support having formed thereon a dielectric layer composed of a terpolymer consisting of (a) methacrylic acid, (b) a monomer selected from the group consisting of (1) acrylic acid esters containing at least 4 carbon atoms and (2) methacrylic acid esters containing at least 5 carbon atoms, and (c) a monomer selected from the group consisting of (1) acrylic acid esters containing at least 4 carbon atoms and (2) methacrylic acid esters containing at least 5 carbon atoms, wherein monomer (b) and monomer (c) are different and at least one of the monomers (b) and (c) is an acrylic acid ester containing at least 11 carbon atoms or a methacrylic acid ester containing at least 8 carbon atoms, and a method for producing an electrostatic recording material, which comprises converting such a terpolymer to a water-soluble or water-emulsifiable salt of the terpolymer in which about 20 to 100 mol% of the carboxyl groups present form a salt with ammonia and/or a volatile amine, dissolving or dispersing the terpolymer salt in water, coating the resulting solution or dispersion onto a support, and drying the coating to volatilize the ammonia and/or volatile amine.
