PURPOSE:To enable prevention of defective fixing or offsetting by using a polymer formed by converting a copolymer contg. a carboxylic group together with a crystalline compd. contg. a carboxylic group to polyvalent metal as a binder resin. CONSTITUTION:A polymer formed by converting a copolymer of an addition polymerizable unsatd. carboxylic acid and other copolymerizable monomer together with a crystalline compd. contg. a carboxylic group to polyvalent metal is used as a binder resin. The addition polymerizable unstad. carboxylic acid is enumerated by an addition polymerizable unstad. aliphat. monocarboxylic acid such as an acrylic acid or an addition polymerizable unsatd. aliphat. dicarboxylic acid such as a maleic acid. The crystalline compd. contg. a carboxylic group is enumerated by a long chain aliphat. carboxylic acid such as polyethylene oxide, melissic acid or the like and further a polyester, polyamide, etc. which are stoichiometrically excessive in acid component. The metal used in the stage of polyvalent metal conversion is enumerated by Al, Ba, Sr, Zn, etc. which are added and heated in the form of alkoxide, sulfate, hydroxide, etc. at 0.01-7% by the total weight, by which the binder resin is obtd. |
