(JA) 眩しさ防止用多層コーティングを備えた透明基板
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a transparent substrate with a multilayer anti-glare coating which can prevent a veiling phenomenon and can prevent disability glare caused by light from a headlight of a coming automobile.

SOLUTION: The transparent substrate with a multilayer anti-glare coating includes a transparent substrate; a first coating layer formed on the transparent substrate and being formed of a first dielectric layer having a refractive index of n1; a second coating layer formed on the first coating layer and being formed of a metal oxide layer having a refractive index of n2; a third coating layer formed on the second coating layer and being formed of a second dielectric layer having a refractive index of n3; and a fourth coating layer formed on the third coating layer and being formed of a third dielectric layer having a refractive index of n4. The refractive indexes of the coating layers satisfy: n1=n3>n2>n4.
