    Abstract: To provide a deinking agent having an excellent ability to remove ink and a good workability whereby a deinked pulp having a high b value and contaminated with little unliberated ink can be obtained either by the flotation method, the washing method or a compromise procedure thereof. A deinking agent which 1) comprises a mixture containing higher fatty acid(s) having 8 to 24 carbon atoms or salt(s) thereof, wherein the average carbon atom number of fatty acids in the mixture ranges from 12.7 to 22.5, the content of higher fatty acid(s) having 20 to 24 carbon atoms or salt(s) thereof ranges from 9.6 to 70.6% by weight and the iodine value (IV) is not more than 45, and 2) does not include alkylbenzenesulfonates. The deinking agent may further comprise an alkylene oxide adduct to an alcohol, a carboxylic acid or a mixture of natural oil and polyhydric alcohol or a sulfonate of the adduct.
