Abstract
(EN)
Oriented composite polyester films with improved adherence in respect of the various final coatings, comprising on at least one of their faces a primary adherence coating formed by co-extrusion of a common crystallisable polyester and of a copolyester with oxysulfonyl groups comprising, for 100 moles of recurrent units of dicarboxylic acid : a) from 78 to 93 moles of terephthalate units; b) from 2 to 5 moles of units derived from an aromatic diacid with one or a number of oxysulfonyl groups; c) from 5 to 17 moles of units derived from at least one alcanediacarboxylic acid comprising from 4 to 15 carbon atoms. These composite films have applications as a final coating support used in packaging, the graphic arts or metal coatings.
(FR)
L'invention concerne des films polyester composites orientés à adhérence améliorée vis-à-vis de revêtements finals variés, comportant sur au moins une de leur face un revêtement primaire d'adhérence formé par coextrusion d'un polyester cristallisable usuel et d'un copolyester à groupes oxysulfonyles comportant pour 100 moles de motifs récurrents d'acide dicarboxylique: a) de 78 à 93 moles de motifs téréphtalates; b) de 2 à 5 moles de motifs dérivés d'un diacide aromatique à groupe(s) oxysulfonyle(s); c) de 5 à 17 moles de motifs dérivés d'au moins un acide alcanedicarboxylique comportant de 4 à 15 atomes de carbone. Ces films composites trouvent applications comme support de revêtements finals utilisés en emballage, dans les arts graphiques ou de couches métalliques.
