Title:
REFLECTION FILM AND REFLECTION PLATE
Document Type and Number:
Japanese Patent JP2008233340
Kind Code:
A
Abstract:
To provide a novel reflection film increasing light reflectivity and dimensional stability under a heated condition.
The reflection film is provided with a layer A containing a polyolefin based resin and a powdery filler and a layer B composed of an oriented polyester film. Excellent light reflectivity can be obtained from refractive scattering due to difference between refractive indices of the polyolefin based resin and the powdery filler in the layer A. Heat resistance of the whole reflection film is enhanced by layering the layer B having excellent heat resistance and the layer A and high excellent dimensional stability is exhibited even in use at a high temperature.
