    摘要: A deinking agent comprising an ester mixture as the active ingredient, wherein the ester mixture is obtained by adding ethylene oxide and propylene oxide to a mixture obtained by reacting a natural fat or a reaction product, obtained by preliminarily reacting a natural fat with glycerol, with a monohydric or dihydric alcohol in such a manner as to give a molar ratio of the alcohol to the glycerol in the natural fat of from 0.02/1 to 1/1. By using the deinking agent of the present invention, a less sticky deinked pulp can be obtained without any foaming troubles or dulling.
