发明名称 LIGHT-REFLECTING ARTICLE
摘要 A light-reflecting article, which comprises an olefinic resin film (1) containing a filler, being stretched at least uniaxially in an area stretching ratio of 1.5 to 80 times, and exhibiting a reflectivity for all light rays of 90 % or more, and at least one substrate of the following materials [1] to [4]: [1] a film (2) comprising at least one of an olefinic resin and a polyester based resin as a main component, [2] a fabric (3) or a non-woven fabric (4), [3] a metal plate (5) [4] a formed article (6) comprising a thermoplastic resin (a1) containing an expanding agent and exhibiting an expansion ratio represented by the following formula (1): expansion ratio = rho0/rho formula (1), wherein rho0 and rho represent a density before expansion and a density after expansion, respectively, of 1.05 to 1 0 times. The light-reflecting article is free from the occurrence of irregularities in the brightness in the face direction resulting from the flexure during the use thereof.
