Embodiment l

[0026] Add 126.6 grams of fluororesin [eterflon 410l, provided by Eternal] (solid content about 60%), add 45 grams of methyl ethyl ketone / toluene each, stir together (speed 1000 rpm), and then add 3 grams of 35nm zinc oxide / barium sulfate in sequence, Hardener [desmodur 3390, provided by Bayer] 18.4 grams to form 250.0 grams of coating (solid content 40%), the coating is coated on the UX-150 (provided by Teijin) substrate, after drying, a coating film of 10 μm can be obtained, and left to stand After 7 days, do weather resistance test (using QUV weather resistance testing machine, Q-panel company). The test results are shown in Table 1 below.

Embodiment 2

[0028] The procedure of Example 1 was repeated except that the substrate UX-150 (supplied by Teijin) was replaced by E60L (supplied by Toray). The test results are shown in Table 1 below.

Abstract

The present invention relates to an optical film. It includes a base material, and is characterized by that at least one base material surface is coated with a coating layer with ultraviolet light absorbing capacity. The invented optical film has good weatherability and has good effect for absorbing UV ray.

Description

technical field [0001] The invention relates to an optical film, which comprises a substrate, and is characterized in that at least one surface of the substrate is coated with a coating with ultraviolet absorbing ability. The optical film of the invention can be used on glass or in flat displays, has good weather resistance, and has the effect of absorbing ultraviolet rays. Background technique [0002] If the human body is exposed to too much ultraviolet rays, it is easy to cause symptoms such as cataracts, skin cancer, burns and skin thickening. Therefore, ultraviolet rays have many adverse effects on the human body. [0003] In addition, if the material is exposed to ultraviolet light for a long time, it will cause damage to the material, and it is prone to yellowing, embrittlement and deformation. [0004] In order to reduce the damage of ultraviolet rays, people have been looking for strong and effective ultraviolet absorbing materials for many years, such as ultraviol...
