Filed Sept. An object of the present invention is to provide a paper coating composition to give paper such excellent properties for printing adaptability as gloss, whiteness, light resistance, wet rubbing strength and picking and a proper stiffness as a coating material for producing such fine printing paper as art paper. It has already been proposed to coat the surface of sized or n-onsized paper, such as sulfite pulp paper, with a coating composition consisting of the three elements of a pigment, binder and assistant in order that the pigment may be secured to the surface of the paper to be coated, the surface of the paper may be made smoother and other properties, such as gloss, whiteness and printability, may be improved in printing paper, such as art paper.

Broadly speaking, there are three different types of EVA copolymer, which differ in the vinyl acetate VA content and the way the materials are used. It is a copolymer and is processed as a thermoplastics material — just like low density polyethylene. It has some of the properties of a low density polyethylene but increased gloss useful for filmsoftness and flexibility. The material is generally considered as non-toxic.

Polyvinyl acetate PVAca synthetic resin prepared by the polymerization of vinyl acetate. In its most important application, polyvinyl acetate serves as the film-forming ingredient in water-based latex paints; it also is used in adhesives. Under the action of free-radical initiators, vinyl acetate monomers single-unit molecules can be linked into long, branched polymers large, multiple-unit moleculesin which the structure of the vinyl acetate repeating units is:. The monomer can be polymerized while dispersed in water to form a milky-white emulsion.
