Abstract
The present invention provides a releasing agent obtained by reacting of an organic polysiloxane having a hydroxyl group or an epoxy group with an ethylenically unsaturated dicarboxylic acid grafted polyolefin or a reaction product of said grafted polyolefin and an active hydrogen atom-containing compound selected from the group consisting of an alcohol, an amine and an aminoalcohol. This releasing agent can be used in a resin composition for use in electrophotographic toner.
Claims23
A releasing agent obtained by reacting an orgainic polysiloxane comprising a hydroxyl group or an epoxy group with an ethylenically unsaturated dicarboxylic acid grafted polyolefin or with a reaction product of said grafted polyolefin and an active hydrogen atom-containing compound selected from the group consisting of an alcohol, an amine and an aminoalcohol.
A resin composition comprising
- (i) 0.5 to 30% by weight, based on the total weight of said resin composition, of a releasing agent obtained by reacting an organic polysiloxane comprising a hydroxyl group or an epoxy group with an ethylenically unsaturated dicarboxylic acid grafted polyolefin or with a reaction product of said grafted polyolefin and an active hydrogen atom-containing compound selected from the group consisting of an alcohol, an amine and an aminoalcohol, and
- (ii) 70 to 99.5% by weight, based on the total weight of said resin composition, of a binder resin.
