摘要： PROBLEM TO BE SOLVED: To prevent an ultraviolet absorbent from bleeding out and thereby enhance the weatherability by forming a base material sheet of a polyolefin thermoplastic resin containing an ultraviolet absorbent with a hydroxyl group in a molecule and forming a primer layer of a resin containing an isocyanate. SOLUTION: A primer layer 13 and a surface protecting layer 14 are laminated on the surface of a base material sheet 11 in order that the surface of a wood base material, a metal base material and the like to be used as a base material for a building is coat-processed. In this base material sheet, the primer layer 13 made of a resin containing an isocyanate is formed on both faces of the base material sheet 11 manufactured of a polyolefin thermoplastic resin containing an ultraviolet absorbent 12 with a hydroxyl group in a molecule. In addition, the surface protecting layer 14 composed of a cured product of an ionizing radiation-curable resin, is formed on the surface of the base material sheet 11. Thus it is possible to obtain the base material sheet 11 which is highly weatherable and is protected against phenomena such as whitening even when the sheet 11 is exposed to ultraviolet rays for a long time. Further a pictorial pattern layer 15 is formed on the back face of the base material sheet 11.

摘要： PROBLEM TO BE SOLVED: To hold followability to a folding, a hardness for particles and a strength against a wear itself by forming a structure of two layers in which a layer obtained by fixing fine particles with a crosslinkable resin is disposed at a lower side and a crosslinkable resin layer having higher flexibility than the previous layer is disposed at an upper side on a surface of a base material. SOLUTION: The decorative material 1 comprises a layer 6 formed of a binder 5 made of fine particles 4 and a crosslinkable resin on an overall surface of a base 2 having a pattern 3, and a layer 7 made of a crosslinkable resin having higher flexibility on the layer 6. As the base 2, any is usable if a material used for an ordinary decorative material is used. In the case of largely classifying, there are groups of various type sheets, a plastic film or sheet, a metal foil, a metal sheet or the like. No blushing or craze of a folding part occurs even by folding at 180 deg. with a coated surface disposed at an outside at an environmental temperature of 20 deg.C, and its wear resistance and folding suitability are sufficient.

摘要： PROBLEM TO BE SOLVED: To enable aqueous wax to be applied smoothly during maintenance services by structuring a decorative material of a slip agent with such a nature as to adsorb moisture, added to the top face of a decorative material of a filmlike, a sheetlike or a platelike shape. SOLUTION: This decorative material is of such a constitution that a slip agent with such a nature as to adsorb moisture is added to the top face of a decorative material of a filmlike, a sheetlike or a platelike shape. The slip agent with such a nature as to adsorb moisture to be used is a polyether- modified silicone oil which has a dimethylsiloxane skeleton in which one methyl group is present or has polyether such as polyethyoxide or polypropylene oxide introduced into both terminals. Thus it is possible to prevent an aqueous wax from being repelled when the aqueous wax is applied and also prevent partial smears from being promoted or partial scratches from being easily inflicted because the aqueous wax is not applied, by using the slip agent.
