Therefore, it is a plastic material that has major drawbacks in terms of durability. In order to improve these drawbacks, recently, coating treatment using a 4& hard paint (hard paint) has been carried out.

に中間介在層を設ける試みかなされている。For example, when a cross-cut deep peel test, boiling water test, and thermal shock test are performed as indicators to evaluate the coated surface, the silane-based AIL coat film easily peels off. Attempts have been made to provide an intermediate intervening layer to form an 8-decoat film on the surface of the molded article that can withstand the perspiration.

However, all of them use the method of S** cloth.Is this liquid metal cloth method superior in forming a thin film?In order to completely remove the II/agent used, the heat distortion temperature of polycarbonate must be 1 or higher. It is necessary to carry out the heat treatment under high temperature conditions, and it takes a long time. Therefore.

The adhesion of the eight-doped coating film to the polycarbonate film is improved. But tl
However, this type of plastic film is significantly inferior in weather resistance because the outermost hard coat film is transparent to ultraviolet rays.

Alternatively, it is manufactured by combining various films with a thickness of 8 by a two-layer extrusion method using a multilayer extruder. The material for the intermediate intervening layer is usually polymethyl methacrylate.

る。The hard coat film completely adheres to the polycarbonate film of the base layer due to the polymethyl methacrylate film of the intermediate intervening layer or the polymethyl methacrylate film modified with other acrylic resin. The agent uses light, especially ultraviolet light. The weather resistance of the multilayer plastic film or sheet of the present invention having the Lm hard code film mixed with the UV-emitting filler on the outermost surface is dramatically improved. Depending on the blending ratio of the filler, it is possible to change the appearance of the plastic film as a final product from translucent to opaque, depending on the blending ratio of the filler. It can be finished in matte or satin tone. Being able to set the appearance of a product to one's preference is extremely useful in today's world where people prefer diversification of designs. Examples of uses include: *For external use, car bodies, signboards and road sign reflectors,
There are signal lights and a meter panel, and for local use there is a front panel with a TV and stereo set. Note that the filler and binder are not necessarily limited to inorganic substances as long as they can block ultraviolet rays that degrade polymeric substances and improve the weather resistance of the product, and 1J pigments and dyes can also be used. .

過傷性の優ねたものであった。On the polymethyl methacrylate film surface of this laminated film, a commercially available silane-based ^R coating agent is applied to a thickness of 1 to 10 μm by a single-sided dip method. This coating agent contains silica fine powder that is 1 to 10 μm thick to the coating agent. Distributed in proportions by weight. This heavy fabric hard coating agent is 80-140℃
Heat treated for 16 to 858 hours. When the formed intermediate valve film of polymethyl methacrylate is thick, the silane-based AR coating agent is cured under low temperature and long time conditions, and when it is thin, high temperature and short time conditions are used. The outer surface of the resulting silane-based AR-coated multilayer film was milky white and translucent with a stunning matte finish.This multilayer film was tested in cross-cut tape peeling tests, boiling water resistance tests, and impact resistance tests. - and subjected to weather resistance tests. The quality evaluation is shown in the table below along with comparative examples. Comparative Example I shows a multilayer film obtained under the same conditions F as in Example 1 except that silica powder was not mixed in the silane-based AIL coating agent. Table 0 showing a film without an intervening layer Example 8 Fine silica powder was dispersed on the polymethyl methacrylate film surface of a laminated film obtained in the same manner as in Example 1 at a ratio of 10 parts by weight. Approximately 3μ of silane AR coating agent
It was applied to rhinoceroses. Curing treatment was performed at sgu° C. for 60 minutes. The obtained multilayer film was cut out into a lO (!l x 20 - square shape) and mounted in the cavity part of an injection mold (lQcm + x 20w x 1L 6 meter meter panel mold) so that the hard coat film forming surface was the outer surface. Under general molding conditions, a molten polycarbonate resin material was injected into the cavity at high pressure using an injection molding machine, and after cooling, the molded product was taken out.The obtained molded product consisted of a multilayer film and molded 411 resin material. The outer surface of the molded product was translucent with a milky white appearance, and had a wonderfully matte finish. Even when the surface was rubbed with a Kinho scrubbing brush, nothing could be detected. It had excellent abrasion resistance and was not susceptible to damage.
