Metallbeschichtete Substrate

摘要

A coated substrate including a substrate; a stack of coating layers provided on the substrate composed of, in the sequence recited, (i) a first layer of dielectric material which is a composite layer including a sub-layer comprising a selectively absorbent material having a refractive index of at least 1.4, a spectral absorption index k lambda of at least 0.4 in the range 380< lambda <450 nm and having a ratio of k380< lambda <450 nm/k650< lambda 760 nm>2, (ii) a first layer of a metal selected the group consisting of silver, gold, copper and alloys of one or more thereof, and (iii) a second layer of dielectric material.
