摘要： A two-in-one colored and translucent film structure suitable for use in backlit displays having a multi-point illumination source. The film structure utilizes a colored layer and a light-diffusing layer that reduces variations in the amount of light transmitted through different areas of a backlit sign. The light- diffusing layer includes light-diffusing particles dispersed in a transparent matrix material, and scatters light transmitted therethrough. The light-diffusing particles have an index of refraction that is different than an index of refraction of the matrix material.

摘要： A protective film that can be included in multi-layer film laminates for use in marketing, advertising campaigns, particularly outdoor or other environment impacted promotions and safety applications. The film includes at least two different polyurethane polymers and is free or substantially free of polyvinyl chloride based polymer. One polyurethane has an ultimate elongation less than 200%, and another polyurethane has an ultimate elongation more than 400%. The film may be transparent, translucent, clear or have other desirable optical properties.
