Title:
RECURSIVE REFLECTING SHEET AND ARTICLE HAVING RECURSIVE REFLECTING PERFORMANCE
Document Type and Number:
Japanese Patent JP3493245
Kind Code:
B2
Abstract:
PURPOSE: To provide a recursive reflecting sheet which is excellent in an adhesive property with a recursive reflecting layer and a printing layer and is excellent in practical durability and is excellent in edge chipping resistance and is excellent in impact resistance and weatherability.
CONSTITUTION: A covering layer is formed by having a surface layer, an intermediate layer and a reverse layer in this order, and here, (i) when the intermediate layer exists in the covering layer, the intermediate layer contains a vinylidene fluoride type polymer as a main component, and the surface layer and the reverse layer contain a methyl methacrylate type polymer as a main component and (ii) when the intermediate layer does not exist in the covering layer, the surface layer is formed by containing a methyl methacrylate type polymer A and a vinylidene fluoride type polymer F in a range that the weight ratio (A:F) is (55:45 to 95:5), and the reverse layer contains a methyl methacrylate type polymer and a vinylidene fluoride type polymer so that the content of the vinylidene fluoride type polymer of the reverse layer becomes more than the content of the vinilydene fluoride type polymer of the reverse layer.
