    摘要: IT HAS BEEN DISCOVERED THAT CERTAIN BLENDS OR POLYMERS CAN BE APPLIED FROM AN AQUEOUS SYSTEM TO GLOSSY SURFACES AND DRIED TO YIELD COATED SURFACES THAT HAVE A PLEASING DEGREE OF ROUGHNESS OR "MATTE" AND THAT ARE WATER AND ABRASION RESISTANT, ANTI-BLOCKING, AND ESSENTIALLY COMPLETELY TRANSPARENT TO VISIBLE LIGHT. THE COATINGS ARE APPLIED TO THE GLOSSY SURFACE IN THE FORM OF AN AQUEOUS LACQUER COMPOSITION COMPRISING (A) WATER, (B) DISSOLVED IN THE WATER, AN EFFECTIVE AMOUNT OF AMMONIUM SALT OR A COPOLYMER OF ETHYL METHACRYLATE AND METHACRYLIC ACID, AND (C) DISPERSED IN THE FORM OF A LATEX THROUGH THE SOLUTION OF (B) IN (A), AN EFFECTIVE AMOUNT OF A HIGHER MOLECULAR WEIGHT POLY(VINYL ACETATE).
