Abstract

The present invention relates to a deinking agent used in recycling printed waste papers, e.g. newspapers, magazines, leaflets and the like, mainly containing one or more additives selected from the group comprising (a) additives made by adding one or more selected from alkylene oxides to at least one selected from dimer acids and polymer acids of higher unsaturated fatty acids having a carbon number of 16~20; (b) additives made by adding one or more selected from alkylene oxides to at least one selected from partial esters which are made of an alcohol having a carbon number of 1~18 and dimer acids and polymer acids of higher unsaturated fatty acids having a carbon number of 16~20; (c) additives made by adding one or more selected from alkylene oxides to one or more selected from dicarboxylic acids or dicarboxylic acid monoesters represented by the formula(I).

(see fig. I) I

wherein one X is COOH and the other X is H or CH3; Y is H or R
and R is an alkyl group having a carbon number of 1~18.
