Abstract

The present invention provides a copying paper which both has good printability and which can be run satisfactory in sheet copying machines. The invention relates to copying paper which inlcudes a base paper based on a fibre starting material of which at least 60% is comprised of short fibre pulp refined to 17-22 DEG SR and at least 20% long fibre pulp refined to 25-38 DEG SR, and filler in an amount of 19-28%, calculated on the base paper. At least one side of the base paper is coated to a surface weight of 12-18 g/m<2>. The copying paper is characterized in that the base component(s) of the coating layer includes/include either a) 100 parts of calcium carbonate distributed according to 60-80 parts of calcium carbonate of which 90% have a particle size beneath 2 mu , and 40-20 parts of calcium carbonate of which 95% have a particle size beneath 2 mu ; or b) 60-90 parts of calcium carbonate of which 90% have a particle size beneath 2 mu , and 40-10 parts of kaolin clay of SPC (selected particle size) quality; and in that the surface coating also includes at least binder and hardener.
