ABSTRACT:
A process is provided for producing a coated printing paper by first applying a pigment containing layer, superposing thereon a surface layer of a thermoplastic latex having a second-order transition of at least 80.degree. C. and an average particle size of smaller than 100 nm to produce a coated printing paper having both superior printability and gloss. Another process is provided for producing a coated printing paper by first applying a pigment containing layer, superposing thereon a surface layer of a thermoplastic latex having a second-order transition of at least 80.degree. C. an average particle size of smaller than 100 nm and lubricants, and treating the surface layer with a calender at a temperature, to produce a coated printing paper having both superior printability and high gloss.
