Abstract
The present invention is an electrophotographic transfer paper where at least one side of the base paper is given a coating layer with a pigment and an adhesive agent to form coated paper and where the aforementioned adhesive contains a branched poly(meth)acrylamide copolymer having a cationic groups and/or anionic groups and also has a weight average molecular weight of 50,000 to 1,000,000. The electrophotographic transfer paper in the present invention has superior high-speed throughput performance despite low basis weight and a low coating weight, therefore, good for high-speed copy machine and printer properties, especially, when it contained a printability improver in the coating layer, it has a good ink adhesion property and surface strength required in offset printing.
