Title
(EN) DECORATIVE FILM AND DECORATIVE ARTICLE USING SAME, AND SURFACE PROTECTIVE COMPOSITION
(FR) FILM DÉCORATIF ET ARTICLE DÉCORATIF L'UTILISANT, ET COMPOSITION DE PROTECTION DE SURFACE
Abstract
(EN)
Provided is a decorative film having excellent weather resistance, scratch resistance, and elongation properties, and a decorative article using the same, and a surface protective composition that can exhibit such properties. 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 higher multimer 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 Formulas 1 to 3 below: 0 ≤ X1 ≤ 2.00... Formula 1 X1 ≤ -0.7 × X2 + 4.67... Formula 2 X1 ≥ -0.7 × X2 + 2.14... Formula 3 where X1 is a numerical value obtained by multiplying the number of branches from a branch point relative to a converted molecular weight of the polyurethane resin by 1000, and X2 is a numerical value obtained by multiplying the number of cyclohexane structure portions included in the polyurethane resin relative to the converted molecular weight of the polyurethane resin by 1000.

La présente invention concerne un film décoratif ayant d'excellentes résistance aux intempéries, résistance aux égratignures, et propriétés d'allongement, et un article décoratif l'utilisant, et une composition de protection de surface qui fait preuve de telles propriétés. Un film décoratif selon un mode de réalisation de la présente invention comprend une couche de protection de surface. La couche de protection de surface contient une résine de polyuréthane obtenue par la réaction d'une composition contenant un polycarbonate diol, et un trimère ou un multimère supérieur d'un diisocyanate comprenant une structure de cyclohexane, d'un diisocyanate comprenant une structure de cyclohexane ou un prépolymère de ce dernier, ou un mélange de ce dernier, et le film décoratif satisfait les formules 1 à 3 ci-dessous : 0 ≤ X1 ≤ 2,00... Formule 1 X1 ≤ -0,7 x X2 + 4,67... Formule 2 X1 ≥ -0,7 x X2 + 2,14... La formule 3 où X1 est une valeur numérique obtenue par la multiplication du nombre de ramifications à partir d'un point de ramification par rapport à un poids moléculaire converti de la résine de polyuréthane par 1 000, et X2 est une valeur numérique obtenue par la multiplication du nombre de portions de structure de cyclohexane comprises dans la résine de polyuréthane par rapport au poids moléculaire converti de la résine de polyuréthane par 1 000.
