まい、光量の低下を引き起こす。(Problem to be Solved by the Invention) However, in such a conventional hesod lamp, when the front lens surface is splashed with muddy water, the front lens is poor in water and oiliness. Since the muddy water that adheres to the headlights does not flow away and dries, the dirt in the muddy water accumulates on the front lens, reducing the amount of light from the headlights. In order to solve this drawback, Japanese Utility Model Publication No. 56-22562 proposes a lens in which a dimethyl silicone film or the like is formed on the lens surface, but this case has the following problems. Although the dimethyl silicone coating is certainly excellent in water repellency, it is poor in oil repellency. It is said that dirt on ordinary roads contains 5 to 15% oily components, and it is not very effective against the oily components contained in such muddy water, and the oily binding makes the dirt more difficult to deal with. It gradually accumulates, causing a decrease in the amount of light.

This solves the above problems.

The surface of the front glass was spray-painted using E60 and Tinuvin 900 manufactured by Ciba Geigy as an ultraviolet absorber to a film thickness of approximately 5 μm. and,
It was dried by heating at 140°C for 30 minutes to form a film. The blending ratio is as shown in Table 2.

め、ついた汚れも簡単に落とすことが可能である。Table 4 In this example, a water-repellent (8 oil-based fluorine compound to melamine hardened film) is formed on the surface of the front glass 5, so muddy water containing oily components that adheres to the vehicle while driving is easily washed off. Therefore, even if it dries, it is difficult for dirt to stick to the front lens.Furthermore, due to the non-adhesive properties unique to fluorine, it is possible to easily remove dirt that sticks to the lens.

について以下に記す。Using the test pieces obtained in Examples 1 to 4 above, the effects of forming a fluorine-containing polyol-melamine cured film were confirmed by evaluating the contact angle and antifouling property, and the results are shown in Table 5. For comparison, Table 5 also shows the evaluation results for glass not coated with a hardened film. The evaluation method is described below.
(I)接触角測定

Dry for 0 minutes. Furthermore, the above cycle was repeated 10 times, and the haze value was measured.

発明による被膜を形成させることにより、ヘイズ価は2

いので、長期にわたって光量の低下を引き起こさない。As is clear from the above results, when there is no cured film of fluorine-containing polyol to melamine resin after the antifouling property test, the haze value is as high as 28.6%, and the adhesion of dirt is significant. Therefore, it is extremely difficult to maintain the light distribution performance specified in JIS 05504. On the other hand, by forming the film according to the present invention, the haze value is 2.
.. The amount is as small as 5 to 3.8%, and there is almost no adhesion of dirt, so the amount of light does not decrease over a long period of time.

性結合によって汚れが堆積しないためと考えられる。This means that the contact angle of the coating with n-hexadecane is 70
~74°, which is larger than 10″ or less when there is no coating, is thought to be because the oily components of dirt do not adhere to the lens surface and dirt does not accumulate due to oily bonds.
