低下し、その機能を失う。When exposed to the outside of the @C layer, deterioration is significant. To prevent this, an ultraviolet absorber is added to the organic polymer material. However, conventional ultraviolet absorbers are organic compounds, which may be dispersed during use or undergo changes in the absorbents themselves due to ultraviolet rays. As time passes for 9 hours, the W-ultraviolet absorbing ability decreases and the filter loses its function.

したが１本発明の紫外線吸収剤を含む塗膜の紫外線透過
率は促進暴露前とほとんど開化がなかった。Using this ultraviolet absorber, a paint was prepared in the same manner as in Example 1, spray coated onto a GQ board, and baked at 140°C for 80 minutes. As a result, a substantially transparent coating film having a thickness of about BO μm was obtained. The UV transmittance of this coating film is 0, approximately 40% of the UV transmittance of the coating film that does not contain the UV absorber of the present invention.
I sang. Further, an Okaji accelerated exposure test was carried out as in Example 1 of #c*, but the UV transmittance of the coating film containing the UV absorber of the present invention showed almost no improvement compared to before the accelerated exposure.

The ultraviolet absorber of the present invention was prepared in exactly the same manner as in Example 1 except that 85 parts by weight of barium fluorosilicate was used. This ultraviolet absorber was a white artificial mica powder containing approximately 16 parts by weight of parium oxide (Bad) and having a thickness of approximately 1 to 5 μm per particle of Q 1 pW1 or less.

の約７０％でありた。Using this ultraviolet absorber, a paint was prepared in the same manner as in Example 1, sprayed onto a glass plate, and baked at 140°C for 30 minutes. This resulted in a coating film with a thickness of approximately 80 μm. This coating film was almost transparent to visible light, and its transmittance to ultraviolet rays with a wavelength of 270 to 320 nm (t meter) was about 70% of the ultraviolet absorption rate of the coating film containing no ultraviolet absorber.
