    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.

    摘要： The present invention is directed to a toner composition containing a polyester resin having an OHV/AV value of 1.2 or more as a major component of a binder resin wherein AV is an acid value of said polyester and OHV is a hydroxyl value thereof and hydrophobic silica having a degree of hydrophobic property of 80 or more or having a pH value of 5.5 to 8 in water-methanol solution. A toner composition of the present invention exhibits no decrease in electric charge retainability and fluidity of a toner and a visible image with good quality for a long period with no black spots occurring.
