Abstract
A synthetic resin shaped article having a mar-resistant polymer surface layer integrated with the polymer body is provided. The mar resistant polymer surface layer consisting essentially of, in polymerized form, (a) 20 to 100 wt.% of a compound having a total of at least three acryloxy and/or metharyloxy groups linked with a straight chain aliphatic hydrocarbon residue having not more than 20 carbon atoms (the hydrocarbon residue may contain at least one ether linkage in the main chain) and (b) 0 to 80 wt.% of at least one copolymerizable mono- or diethylenically unsaturated compound.
