From the result that the retention rate (%) after 240, 360 and 480 hours showed a high value, it was found that excellent light resistance could be realized by using the granular ultraviolet absorbent of each example. Moreover, it turned out that it can implement
  • permeability of the ultraviolet-ray with a wavelength of 400 nm were measured.
  • the obtained plastic bottle (container) efficiently absorbs ultraviolet rays and sufficiently secures visible light transmittance. I understood.
  • NIR absorption layer For 100 parts by mass of norbornene resin (manufactured by JSR Corporation, product name: ARTON F5023), a diimonium compound (manufactured by Nippon Kayaku Co., Ltd., product name: IRG-) 068) Resin solution consisting of 0.3 parts by mass and 2000 parts by mass of dichloromethane as a solvent is cast on a surface-polished glass plate using a bar coater, pre-dried at 50 ° C. for 20 minutes, and at 90 ° C. for 30 minutes. After drying a film having a thickness of 50 to 60 ⁇ m, a square film test piece having a side of 2 cm was obtained.
  • norbornene resin manufactured by JSR Corporation, product name: ARTON F5023
  • IRG- diimonium compound
  • test light was irradiated from the ultraviolet absorption layer side with a sunshine weather meter (manufactured by Suga Test Instruments Co., Ltd .; 83 ° C., no rain, light source carbon arc). The exposure was for 360 (or 540) hours in such a way.
  • the transmittance at the maximum wavelength (NIR absorption layer: 1100 nm) in the NIR region before and after the light resistance test was measured, and the light resistance was evaluated by the transmittance attenuation rate ( ⁇ transmittance).
  • the granular ultraviolet absorbers of Examples 1 to 5 are excellent in dust property and fluidity as compared with Comparative Example 1, and are excellent in melt-kneading property as compared with Comparative Example 2, so that they exhibit good powder characteristics. I understood. In addition, it was found that the compounds of Examples 1 to 5 are excellent in ultraviolet absorption characteristics and can be suitably used as an ultraviolet absorber.
