Abstract

The invention relates to gloss and matt varnish replacing UV oil for printing and application thereof.The gloss and matt varnish comprises gloss oil and matt varnish, and the gloss oil comprises, by mass, 9.46-10.71 parts of waterborne polyurethane resin emulsion, 74.29-76.82 parts of waterborne acrylic resin emulsion, 6 parts of solvent, 3 parts of cosolvent and 1-7 parts of auxiliaries; the matt varnish is prepared from the following components in parts by mass: 5.68 to 8.12 parts of waterborne polyurethane resin emulsion, 74.44 to 79.32 parts of waterborne acrylic resin emulsion, 6 parts of a solvent, 3 parts of a cosolvent and 1 to 7 parts of an auxiliary agent. The method is used for replacing the technical application of UV oil local brightening to solve the quality problems of incomplete curing, poor adhesive force, uneven glossiness, yellowing and the like, so that the quality of a printed matter is ensured, the surface of the printed matter also has super-strong wear resistance and local glossiness, and the method has stronger competitive advantages in similar products.
