Polyamide resin, and polymer film, resin laminate using the same

Abstract

The present invention relates to a polyamide resin in which an average particle size of individual crystals measured by a small-angle X-ray scattering apparatus is 8.0 nm or less, and a UV-cut slope (dT/dλ) measured for a specimen having a thickness of 45 μm or more and 55 μm or less according to ASTM E424 is 0.25 or more in the range of 10% to 80% transmittance, and a polymer film and resin laminate using the same. In addition, the present invention relates to a polyamide resin with characteristic profile in which a small-angle X-ray scattering function obtained by irradiating the polyamide resin with X-rays having an energy of 10 KeV to 20 KeV using a small-angle X-ray scattering apparatus satisfies Equation 1 and Equation 2, and a polymer film and resin laminate using the same.
