。<Prior art> Conventionally, commonly used powder coatings have a backbone of polyester resin, acrylic resin, epoxy resin, etc., and are made into fine powder by blending pigments, crosslinking agents, leveling agents, etc. . The powder coating prepared in this way is applied to a base material by a method such as an electrostatic spray method or a fluidized dipping method.
It melts at a temperature higher than the melting point of the skeleton resin and lower than the thermal decomposition temperature, and is used in a construction method that forms a continuous film.
したがって、粉体塗料は、無溶媒で用いることができ、
液体型塗料と、比較して、無公害性に優れている。Therefore, powder coatings can be used without solvents,
Compared to liquid paints, it is superior in non-polluting properties.

により平滑性を得ると、その加工物性や生産性、経済性
等に問題があった。Problems to be Solved by the Invention However, since the difference between the melting point temperature and thermal decomposition temperature of the skeleton resin used in powder coatings is generally small, the temperature at which sufficient flowability can be obtained during melt processing is It's difficult to take the time. Therefore, the leveling property is poorer than that of liquid-type paints, and it is not possible to obtain a smooth painted surface with a mirror-like appearance. If the flowability is improved by lowering the melting point of the skeleton resin, the surface properties will deteriorate. Furthermore, when smoothness is obtained by significantly increasing the thickness of the coating layer, there are problems with processing properties, productivity, economic efficiency, etc.
そこで、本発明は、粉体塗装を行なう場合に、鏡面外観

After removing it using an abrasive material such as sandpaper or abrasive cloth, it is coated using a roll coater, curtain flow coater, spray, etc., and cured by irradiation with an ultraviolet lamp. At this time, the coating thickness of the photopolymerizable resin layer 3 is suitably about 5 to 50 μm, but if the surface of the powder coating layer 2 is ground, the coating thickness may be about 2 to 20 μm.
