Title:
RETROREFLECTIVE SHEET
Document Type and Number:
WIPO Patent Application WO/2015/137217
Kind Code:
A1
Abstract:
This retroreflective sheet (1) has the following: a single retroreflective layer (10) consisting of both a flat retainer section (11) and an integrated retroreflective-element section (12) comprising a plurality of retroreflective elements formed on the retainer section (11); and a space-forming layer (20) that partially contacts the surface of the retroreflective layer (10) where the retroreflective-element section (12) is, forming a space between said space-forming layer (20) and the retroreflective-element section (12). The elastic modulus of the retroreflective layer (10) is between 9.0×108 Pa and 15.0×108 Pa, inclusive, and the ratio of the thickness (TH2) of the retainer section (11) to the thickness (TH1) of the retroreflective-element section (12) is between 0.5 and 1.0, inclusive.
