Patent ID: 7776435

Claim:
An electrophotographic transfer paper where at least one side of a base paper has a coating layer with a pigment and an adhesive agent forming a coated paper, wherein the adhesive agent contains (1) 1.0 to 10.0 parts by weight of branched poly(meth)acrylamide copolymer having a cationic group and/or an anionic group and has a weight average molecular weight of 50,000 to 1,000,000, with respect to 100 parts by weight of pigment, (2) 5 to 9 parts by weight of styrene-butadiene system copolymer latex as dry solid content to 100 parts by weight of pigment, and (3) 3 to 7 parts by weight of starch to 100 parts by weight of pigment, wherein the ratio of (the branched poly(meth)acrylamide copolymer):(the styrene-butadiene system copolymer+the starch) is between 5:95-50:50; and wherein at least 50 parts by weight of pigment within 100 parts by weight of pigment is the kaolin, which has a particle distribution of that at least 65% thereof has the particle size of 0.4 to 4.2 μm by volume.
