Title:
GLARE REDUCING GLAZING ARTICLES
Document Type and Number:
WIPO Patent Application WO/2012/078543
Kind Code:
A3
Abstract:
Glazing articles that reduce glare include a glazing substrate, and a reflective polarizing film article attached to the glazing substrate. The reflective polarizing film article includes a reflective polarizing film, and a reflection inhibitor layer. The reflective polarizing film articles reduce transmission of polarized light with a polarization block axis that is horizontal, and reduce horizontally polarized light to 90% or less of the horizontally polarized incident visible light. The reflective polarizing film may include a multi-layer film construction. The reflection inhibitor layer may include a tinted layer or an absorptive polarizer layer. Glazing units that reduce glare include at least one glazing substrate, at least one reflective polarizing film, and at least one reflection inhibitor layer. The glazing substrate, reflective polarizing film, and reflection inhibitor layer may or may not be in contact with one another.
