The invention provides optical parts having good impact resistance, good adhesiveness between the substrate and a thin film layer formed thereon, good scratch resistance and good antireflection capabilities. A coating composition comprising at least one selected from dithian ring skeleton-having sulfur compounds of a general formula (1):
wherein n is an integer of from 1 to 3,
and benzene ring-having sulfur compounds of a general formula (2):
wherein m is 0 or 1,
and a polyfunctional thiol is applied onto the surface of a plastic substrate to form thereon a thin film layer.
