Abstract

PURPOSE:To make the surface of a film smooth and transparent by eliminating an extremely minute unevenness, by forming a color ink film on a pattern by using a printing ink, and thereafter, polishing the film surface by using a lapping film and a material by a fine particle of alumina, etc. CONSTITUTION:A color ink film surface becomes a circular arc shape in a picture element of each color, and when a second color and a third color are printed and lapped, the film thickness becomes minimum in a boundary of each color, and the film thickness becomes maximum in the center part of each color. In this way, as a color ink film 12, three colors of red, green and blue are printed on a substrate 11, and thereafter, by using a lapping film to which a fine particle of alumina, etc., has been stuck, a swell part in each color picture element is eliminated, and a rough surface whose film thickness is uniform is formed. Thereafter, the rough film surface is polished by an abrasive material which has mixed and diffused a fine particle of alumina, zirconia, diamond, etc., into a solution whose main component is water or alcohol. In this way, an extremely smooth surface is obtained, the optical characteristic is improved, and the transparent sense is improved.

In particular, when the ink h''-1 used in the present invention is printed and formed on a substrate such as glass, and the main body is a varnish containing a volatile solvent, the ink solvent h''-1 contained in the ink rapidly increases after 1 hour has passed after printing. The ink evaporates to a higher altitude. As a means to smooth hard coatings,
When polished with a wrapping film, the diameter becomes 10 μm.
In this manner, protrusions having a height of 1 to 60 μm are removed. A characteristic of polishing with wrapping film is that only the convex parts are removed without touching the concave parts.
