LAMINATED GLASS AND INTERLAYER USED THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide both a laminated glass having a high visible light transmittance and transparency and excellent in durability and an interlayer used therefor. SOLUTION: This interlayer is obtained by dispersing the below-mentioned zinc oxide-based grains in a cured product thereof and the laminated glass comprises at least two sheets of transparent plates and the resin interlayer sandwiched between the two sheets of the transparent plates. The resin interlayer contains the above interlayer. The zinc oxide-based grains contain a metal element (Md) taking a valence of 3 and/or 4 and Zn as metal components, manifest X-diffractometric zinc oxide crystallinity and satisfy Ds(002)/Ds(100)<2 when the size of crystallites in the vertical direction Ds(hkl) is determined for two lattice planes (100) and (002) by using the Scherrer method (Cauchy function approximation) and further satisfy 1<Dw<30 (nm) when the size of the crystallites determined by using the Wilson method is Dw.
