Abstract

Film destiné à couvrir une plaque de métal décorative, qui comporte une résine téréphtalate de polybutylène ayant une viscosité intrinsèque de 1,0 à 2,0 et dont au moins une surface est finie par gaufrage. La présente invention concerne également une plaque de métal décorative qui comporte une plaque de métal et ledit film de résine appliqué sur cette plaque. Ledit film pour une plaque de métal décorative possède une aptitude au traitement identique, pour ce qui est du gaufrage et du moulage, à celle d'une résine chlorure de polyvinyle classique, voire meilleure, et possède une excellente résistance à l'eau pendant une longue période.
