Decorative film, decorative article using the decorative film, and surface protective composition

摘要

Problem to be solved: to provide decorative film excellent in weather resistance, scratch resistance and elongation property, decorative article using the decorative film, and surface protective composition capable of performing such performance.A decorative film having a surface protective layer;Surface protective layerPolycarbonate diolMultimeric trimer or diisocyanate containing cyclohexane structureDiisocyanate containing cyclohexane structure or its prepolymerOr a polyurethane resin that reacts with the composition containing these mixturesAndThe decorative film that satisfies the following expressions 1 to 3: 0 ≦ x 1 ≦ 2.00X1 × X + 4.67X1 ≧ 0.7 × X + 2.14...In the equation, X1 is a value obtained by multiplying the number of branches at the branch point with respect to the converted molecular weight of the polyurethane resin by 1000 times, and X2 is a value obtained by multiplying the number of the cyclohexane structure part in the polyurethane resin to the converted molecular weight of the polyurethane resin by 1000 times.]Diagram
