ANTI-IRIDESCENCE COATINGS |
摘要 |
A glazing article comprises a substrate bearing a substantially transparent coating comprising an optically functional topcoat and a thinner anti-iridescence layer undercoat mediate the topcoat and the substrate. The anti-iridescence layer eliminates or substantially reduces iridescence and, in addition, is readily designed to make the overall coating either colorless or to provide a substantially uniform muted color. The antiiridescence layer comprises a first thickness zone in which the refractive index is higher than that of the substrate. A low refractive index zone is positioned directly on the high refractive index zone. A second high refractive index zone is positioned on the low refractive index zone, such that the low refractive index zone is directly sandwiched between the two high refractive index zones. A fourth zone, a low refractive index zone, follows the second high refractive index zone. Anti-iridescence is provided for a wide variety of optically functional topcoats without significant impairment of the optical performance thereof. Certain preferred embodiments are particularly well adapted for low emissivity glazing for architectural applications. |
