  • the base resin layer and the colored resin layer made of a polybutyrene terephthalate film have little fluctuation in expansion and contraction due to heat and tension, and have excellent dimensional stability, high-definition printed matter with good printing register accuracy Can be obtained.
  • the decorative film can be obtained using the same manufacturing method and manufacturing conditions as the conventional polyvinyl chloride resin film, there is no need for capital investment such as the addition of new equipment or the modification of equipment.
  • film it is possible to express a high-definition picture pattern with excellent design, in which the printed pattern and the embossed pattern are synchronized.
  • the resin constituting the base resin layer and the surface resin layer does not contain a plasticizer, problems such as surface contamination due to bleeding of the plasticizer do not occur, and contamination resistance, solvent resistance, Excellent surface properties such as water resistance.

Abstract

La présente invention concerne un film de résine d'impression destiné à la stratification de feuille stratifiée décorative de grande netteté ayant une usinabilité, une netteté et des modèles d'impression, et dont les caractéristiques de conception, l'adaptabilité à l'environnement et les propriétés physiques de surface, telles que la résistance à la contamination et aux solvants, sont excellentes. Cette invention concerne également une feuille stratifiée décorative de grande netteté stratifiée avec ces films de résine. Ce film de résine d'impression (1) destiné à la stratification de feuille stratifiée décorative de grande netteté se caractérise en ce qu'il présente, en tant que couche de résine superficielle (11), un film de résine orienté présentant un facteur d'orientation superficielle et une différence entre une valeur maximum et une valeur minimum d'indice de réfraction dans le plan définie dans des plages préétablies, et en ce qu'il est stratifié, pour ses couches inférieures, avec une couche de résine transparente excellente pour l'impression en relief, une couche d'impression, une couche de résine de matériau de base (7), une couche de résine de coloration (5) et une couche de résine d'adhésion (4). La feuille stratifiée décorative de grande netteté (12) est caractérisée en ce que les films de résines susmentionnés sont stratifiés sur un substrat(2).
