Title:
COATED PAPER FOR PRINTING AND MANUFACTURING METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2011/115167
Kind Code:
A1
Abstract:
Disclosed is a technique for efficiently manufacturing, by means of curtain coating, coated printing paper which exhibits excellent print quality and whereon minute un-coated sections (craters) are unlikely to be generated, even in high-speed coating. Specifically, the disclosed coated printing paper manufacturing method includes: a step wherein water, pigments, and a viscosity modifier formed from a W/O emulsion, wherein an aqueous solution of a polycarboxylic acid copolymer having a weight-average molecular weight of 4-50 million is dispersed in an organic solvent, are mixed and a coating liquid is prepared; and a step wherein a curtain layer of the coating liquid is formed, and base paper is passed through the curtain layer, forming a coating layer on the base paper.
