SOIL-PROOF SHEET

Japanese Patent JP3880256

B2

PROBLEM TO BE SOLVED: To provide a stain-proof sheet which is free from the transfer elution of a plasticizer and so on from a PVC-containing intermediate layer to a stain- proof layer and has excellent stain resistance, weather resistance, touch and mechanical characteristics and high durability.
SOLUTION: This stain-proof layer is obtained by forming a PVC-containing intermediate layer on a base fabric, and then forming a stain-proof layer comprising, for example, an acrylic resin, or a photocfatalytic inorganic material and a binder on the intermediate layer. Therein, the PVC resin for the intermediate layer contains as plasticizers (1) polyester-based, trimellitate-based and/or pyromellitate-based liquid plasticizers in an amount of 40 to 100 pts.wt. per 100 pts.wt. of the PVC and/or (2) ethylene-vinyl acetate-CO terpolymer and/or ethylene-acrylate-CO terpolymer high mol.wt. plasticizers in an amount of 50 to 120 pts.wt. When both the plasticizers (1) and (2) are used, their total amount is ≤120 pts.wt.
