Abstract:
(EN) The present invention addresses the problem, in a method for manufacturing a decorative molded article by means of simultaneous molding and decoration using a decorative film having a minute three-dimensional pattern formed on a surface thereof, of suppressing deformation of the minute three-dimensional pattern and improving visually-perceived quality of feel, such as texture and touch. A decorative film (20) having a thermoplastic resin film having a three-dimensional pattern formed on a surface thereof is set in a mold (100), the three-dimensional pattern being constituted by a plurality of minute convex shapes having a height of 0.35 mm or less, and a thermoplastic resin in a melted state in which a supercritical fluid has been poured is injected into a cavity (130) of the mold (100), whereby the supercritical fluid is foamed to mold a decorative molded article (10) in which a molded body (30) having a weight reduction ratio of 5% or more and 20% or less and the decorative film (20) are integrally molded.
(FR) La présente invention aborde le problème, dans un procédé de fabrication d'un article moulé décoratif au moyen d'un moulage et d'une décoration simultanés à l'aide d'un film décoratif ayant un motif tridimensionnel minuscule formé sur une de ses surfaces, de suppression de la déformation du motif tridimensionnel minuscule et d'amélioration de la qualité de toucher perçue visuellement, telle que la texture et le toucher. Un film décoratif (20) ayant un film de résine thermoplastique ayant un motif tridimensionnel formé sur une de ses surfaces est placé dans un moule (100), le motif tridimensionnel étant constitué d'une pluralité de minuscules formes convexes ayant une hauteur de 0,35 mm ou moins et d'une résine thermoplastique dans un état fondu, dans lequel un fluide supercritique a été versé, est injecté dans une cavité (130) du moule (100), le fluide supercritique étant moussé pour mouler un article moulé décoratif (10) dans lequel un corps moulé (30) ayant un rapport de réduction de poids de 5 % ou plus et 20 % ou moins et le film décoratif (20) sont moulés d'un seul tenant.
(JA) 予め加飾フィルムの表面に微細な立体模様が形成された加飾フィルムを用いた成形同時加飾による加飾成形品の製造方法において、微細な立体模様の変形を抑制して視覚で知覚される質感及び手触りなどの風合いの質を向上させることを課題とし、高さ0.35mm以下の微細な複数の凸形状で構成された立体模様が表面に形成されている熱可塑性樹脂製フィルムを有する加飾フィルム(20)を金型(100)にセットし、超臨界流体が注入された溶融状態の熱可塑性樹脂を金型(100)のキャビティ(130)の中に射出することで、軽量化率が5%以上20%以下の成形体本体(30)と加飾フィルム(20)とが一体的に成形された加飾成形品(10)を、超臨界流体を発泡させることにより成形する。
