Provided are a decorative film having excellent weather resistance, scratch resistance, and elongation characteristics, a decorative article using the same, and a surface protection composition that can exhibit such characteristics. A decorative film according to one embodiment of the present disclosure includes a surface protective layer. The surface protective layer contains a polyurethane resin obtained by reacting a composition containing a polycarbonate diol, and a trimer or a higher polymer of a diisocyanate including a cyclohexane structure, a diisocyanate including a cyclohexane structure or a prepolymer thereof, or a mixture thereof, and the decorative film satisfies the following formulae 1 to 3: 0 < = X1 < = 2.00... Formula 1 X1 < =-0.7 * X2 + 4.67... Formula 2 X1 > =-0.7 * X2 + 2.14... Formula 3 wherein X1 is a numerical value obtained by multiplying the number of branches starting from a branching point with respect to the equivalent molecular weight of the polyurethane resin by 1000, and X2 is a numerical value obtained by multiplying the number of branches starting from a branching point with respect to the equivalent molecular weight of the polyurethane resin by 1000. And X2 is a value obtained by multiplying the number of cyclohexane structural moieties included in the polyurethane resin by 1000 with respect to the equivalent molecular weight of the polyurethane resin.
提供了一种具有优异的耐候性、耐刮擦性和伸长特性的装饰膜和使用该装饰膜的装饰制品,以及可以表现出此类特性的表面保护组合物。根据本公开的一个实施方案的装饰膜包括表面保护层。该表面保护层包含聚氨酯树脂,该聚氨酯树脂通过使包含以下各项的组合物反应而获得:聚碳酸酯二醇,以及包括环己烷结构的二异氰酸酯的三聚体或更高级多聚体、包括环己烷结构的二异氰酸酯或其预聚物、或它们的混合物,并且该装饰膜满足下式1至3:0≤X1≤2.00...式1X1≤‑0.7×X2+4.67...式2X1≥‑0.7×X2+2.14...式3其中X1是通过将相对于该聚氨酯树脂的换算分子量的从分支点开始的分支的数量乘以1000而获得的数值,并且X2是通过将相对于该聚氨酯树脂的换算分子量的包括在该聚氨酯树脂中的环己烷结构部分的数量乘以1000而获得的数值。
