PURPOSE:To prevent an offset and to obtain the titled resin for a development having a lower fixing temp. by reacting a prescribed amount of two or more valence carboxylic acid having a tertiary amino group in a polymerization of a specific monomer. CONSTITUTION:In a polymerization of (a) component of styrene and/or a styrene derivative and (b) component of at least one of a monomer selected from a group of methacrylic acid, acrylic acid and its ester, a component (c) of the two or more valence carboxylic acid contg. a tertiary amino group is reacted. An ester of acrylic acid or methacrylic acid having at least one of a hydroxyl group or an epoxy group of the component (b) is an equimolar or more amount per a mole of the component (c). The (c) is contained 0.05-50wt% on the weight basis of the total monomer, and is preferably the two or more valence carboxylic acid contg. the tertiary amino group shown by formulas (I)-(IV). |
