TRANSPARENT THIN-WALL SCRATCH-RESISTANT ARTICLE

摘要

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.
