Abstract
(EN)
The present invention relates to a polyamide resin, and a polyamide film and a resin laminate each using same, wherein the polyamide resin has: an average particle diameter of individual crystals of 8.0 nm or smaller, as measured by a small angle X-ray scattering apparatus; and a UV-cut slope (dT/dλ) of 0.25 or greater in the transmittance range of 10-80%, as measured according to ASTM E424 for a specimen having a thickness of 45-55 ㎛. In addition, the present invention relates to a polyamide resin, and a polymer film and a resin laminate each using same, wherein in the polyamide resin, the small angle X-ray scattering function, obtained by irradiating the polyamide resin with X-rays having an energy of 10-20 KeV using a small angle X-ray scattering apparatus, has a characteristic general shape satisfying the conditions of mathematical formulas 1 and 2.

La présente invention concerne une résine polyamide, et un film de polyamide et un stratifié de résine utilisant chacun celle-ci, la résine polyamide présentant : un diamètre de particule moyen de chaque cristal égal ou inférieur à 8,0 nm, tel que mesuré par un appareil de diffusion des rayons X aux petits angles; et une pente de coupure des UV (dT/dλ) égale ou supérieure à 0,25 dans la plage de transmission de 10 à 80 %, telle que mesurée selon la norme ASTM E424 pour un échantillon présentant une épaisseur de 45 à 55 µm. De plus, la présente invention concerne une résine polyamide, et un film polymère et un stratifié de résine utilisant chacun celle-ci. Dans la résine polyamide, la fonction de diffusion des rayons X aux petits angles, obtenue par exposition de la résine polyamide à des rayons X présentant une énergie de 10 à 20 KeV à l'aide d'un appareil de diffusion des rayons X aux petits angles, présente une forme générale caractéristique conforme aux conditions des formules mathématiques 1 et 2.
