RETROREFLECTIVE SHEET
PROBLEM TO BE SOLVED: To provide a retroreflective sheet that offers desired reflective performance and superior flexibility.SOLUTION: A retroreflective sheet 1 of the present invention includes; a retroreflective layer 10 which is a monolayer comprising an integrally formed tabular holder portion 11 and a retroreflective element portion 12, the retroreflective element portion consisting of a plurality of retroreflective elements formed on the holder portion 11; and a bonding material layer 20 partially adhering to the retroreflective element portion 12, and forming void spaces between the retroreflective element portion 12 and itself. The retroreflective layer 10 has an elasticity modulus in a range of 9.0×10Pa to 15.0×10Pa, inclusive, and a ratio of a thickness TH1 of the retroreflective element portion 12 to a thickness TH2 of the holder portion 11 is in a range of 0.5 to 1.0, inclusive.SELECTED DRAWING: Figure 1
【課題】所望の反射性能を得つつ柔軟性に優れる再帰反射シートを提供する。【解決手段】本発明の再帰反射シート１は、板状の部位である保持体部１１と、保持体部１１に形成される複数の再帰反射素子からなる再帰反射素子部１２とを一体化した単層の再帰反射層１０と、再帰反射素子部１２と部分的に密着され、再帰反射素子部１２と自身との間に空間を形成する結合材層２０とを備える。再帰反射層１０の弾性率は９．０×１０８Ｐａ以上１５．０×１０８Ｐａ以下であり、再帰反射素子部１２の厚さＴＨ１に対する保持体部１１の厚さＴＨ２の比は、０．５以上１．０以下である。【選択図】図１
