Title (EN) TRANSPARENT THIN-WALL SCRATCH-RESISTANT ARTICLE
(FR) ARTICLE TRANSPARENT À PAROIS MINCES RÉSISTANT À LA RAYURE
Abstract: front page image
(EN)A plastic article is described having a substrate of a substantially transparent substrate having a thickness of from 0.2 mm to 3.0 mm, and including a thermoplastic composition comprising a polycarbonate and having a melt flow index as defined by ASTM D1238 of 10 g/10min. to 50 g/10min. at 300°C and a 1.2 kg load, the thermoplastic composition including a polycarbonate, the thermoplastic composition comprising 20 mol% to 80 mol% of specified cyclohexylidene-bridged carbonate units and 80 mol% to 20 mol% of specified other carbonate units. The substrate has a hard coat thereon that provides the article with a pencil hardness of at least 5H as determined according to JIS K5400 using a 0.75 kgf load.
(FR)L'invention porte sur un article en plastique ayant un substrat constitué d'un substrat pratiquement transparent ayant une épaisseur de 0,2 mm à 3,0 mm et comprenant une composition thermoplastique comprenant un polycarbonate et ayant un indice de fluage à l'état fondu, défini par la norme ASTM D1238, de 10 g/10 min à 50 g/10 min à 300°C et sous une charge de 1,2 kg, la composition thermoplastique comprenant un polycarbonate, la composition thermoplastique comprenant 20 % en mole à 80 % en mole de motifs carbonate pontés par des groupes cyclohexylidène spécifiés et 80 % en mole à 20 % en mole d'autres motifs carbonate spécifiés. Une couche dure est appliquée sur le substrat, laquelle couche dure confère à l'article une dureté crayon, déterminée selon la norme JIS K5400 à l'aide d'une charge de 0,75 kgf, d'au moins 5H.
