PROBLEM TO BE SOLVED: To provide an antifouling coating composition for wallpaper which is excellent in surface characteristics such as fouling-proofness and fouling-removability in addition to surface strength.SOLUTION: The antifouling composition for wallpaper includes: an aqueous urethane resin composition including an urethane resin composed of an aqueous urethane resin having the following physical properties (a): 100%-modulus of 100-200 [kg/cm]; tensile strength of 200-250 [kg/cm]; and elongation force of 200-280 [%], and fumed silica having the following physical properties (b); specific surface area of 77-190 [m/g]; apparent specific gravity of 15/100 [g/L]; average particle size of 1.2-3.5 [μm], and a treatment agent of a vinyl chloride copolymer emulsion or acrylic copolymer emulsion, which is mixed to the aqueous urethane resin composition. |
