LIGHT-REFLECTING BODY AND SURFACE LIGHT SOURCE USING SAME

摘要

A light-reflecting body is disclosed which has an all light reflectance of 95% and a surface strength of not less than 250g. The light-reflecting body contains a multilayer film composed of a base layer (A) and a thermoplastic resin-containing layer (B). The base layer (A) contains a thermoplastic resin and a filler, and is stretched at least uniaxially so as to have an area draw ratio of 1.3-80. This light-reflecting body is excellent in optical characteristics, and has such excellent workability that the light-reflecting body hardly becomes loose or is partly/totally separated from the sheet material when it is bonded to one of various sheet materials and then formed into a shape.
