    摘要： Multilayer reflecting polarizing films are disclosed having increased in-plane refractive index differences between adjacent microlayers along both the pass and block axis, and having negative refractive index differences between adjacent microlayers along the thickness or z-axis. Major front and back surfaces of the film exposed to air provide a Fresnel reflectivity component to the pass axis reflectivity, and the microlayers provide a microlayer component to the pass axis reflectivity, such microlayer component preferably having a reflectivity of p-polarized light that increases with incidence angle faster than the Fresnel reflectivity component decreases so as to substantially avoid off-axis gain peaks for p-polarized light. The films preferably utilize a relatively small total number of microlayers, arranged in a single coherent stack with monotonic optical repeat unit thickness profile, and at least some microlayers preferably include polyethylene naphthalate or a copolymer thereof.

    摘要： 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.
