ABSTRACT:
In a method of producing cast coated paper in which a wet coating layer containing as its main components, pigment and adhesive, is heated to permit a gel state to be formed in the layer, or is dried and then rewetted, and then is pressed against a highly polished finishing surface of a heated drum so as to be provided with a glazed finish.
The present invention provides an improvement wherein an apparatus for emitting near-infrared radiations into the wet coating layer is employed as a means for permitting a gel state to be formed in the layer or as a means for drying the wet coating layer. The apparatus emits near-infrared radiations having wave lengths of 0.75 to 2.0 .mu.m at the peak wave length of their range which are directed into the wet coating layer.
