ABSTRACT:
The present invention provides a method of producing a cast coated paper including the steps of providing a pigment coating layer for casting on a base paper, plasticizing the coating layer by means of a rewet liquid, and drying the coating layer by pressing the coating layer against a heated metal drum having a highly polished surface such that the dried coating layer has a high gloss. The rewet liquid is an aqueous dispersion having a complex resin. The complex resin includes a copolymer resin and a colloidal silica, the copolymer resin being obtained by copolymerizing a styrene monomer and an unsaturated carboxylic ester monomer, and the colloidal silica having a mean particle diameter ranging from 0.005 .mu.m to 0.01 .mu.m.
