发明名称 Method of manufacturing coated paper for printing
摘要 The method of making a coated paper having a thermal shrinkage force (R), which satisfies the following relationship 0<=R<=45 gf, includes coating a paper web on both sides with an aqueous solution of polyvinyl alcohol to form a coated paper web, drying the coated paper web to form a base paper with a polyvinyl alcohol coating having a coating weight on a dry basis of 0.5 to 5.0 g/m2 per side of the base paper and then applying a coating composition composed of an adhesive and at least one inorganic pigment to the base paper having the polyvinyl alcohol coating, followed by drying in order to form a coating layer on the base paper. The aqueous solution of the polyvinyl alcohol preferably has a viscosity of from 100 to 2000 mPa.s measured with a Brookfield viscometer at 60 rpm and 20° C. and the polyvinyl alcohol dissolved in the aqueous solution has a saponification degree of not less than 85 mol %. The base paper preferably has an air resistance of 1000 seconds or higher based on the measurement pursuant to JIS-P-8117.
