<p>PURPOSE:To improve compatibility with a resin for fixing toners and electrostatic chargeability by copolymerizing cation monomer among a monoallylamine, diallylamine and triallylamine and another polymerizable monomer. CONSTITUTION:This resin consists of the copolymer contg. the polymerizable monomer capable of constituting a polymer having good compatibility with the resin for fixing toners or the polymerizable monomers to be the source for the resin for fixing toners and the cationic monomer of at least one kind among the monoallylamine, diallylamine and triallylamine. The ratio at which the cationic monomer occupy in the charge control resin is preferably specified to 5 to 20wt.% when expressed by the ratio of the cationic monomer occupying the total amt. of the monomers as the raw material. A monovinyl arom. monomer, acrylic monomer, etc., are usable as such polymerizable monomer. As a result, the charge controllable resin which has the excellent compatibility with the resin for fixing toners or the polymerizable monomer to be the source for the resin for fixing toners, is insoluble in water and has excellent electrostatic charge characteristics is obtd.</p> |
