PURPOSE:To improve resistance to wear, heat and hot water by using the specific components which prevent from cracking even if the film thickness of a hard coat layer is increased. CONSTITUTION:Single or multiple layers of antireflection films are provided on the surface of a lens on which the coating compsn. contg. >=1 kind of the monomers expressed by the formulas I , II and III, colloidal silical having 1-100mmu grain size, 1 or >=2 kinds of hydrolyzate or partial condensate of the silicon compd. expressed by the formula VI, multifunctional epoxy compd. and curing catalyst as an essential component is coated and cured. R<1>, R<2> in the formulas I , II, III are a hydrocarbon group (C1-C12) and the formula VI. R<5>, R<6> in the formula VI denote a hydrocarbon group (C1-C6), etc. and R<7> denotes -O-, -S-, -SO2-, etc. X denotes halogen except fluorine and hydrocarbon group (C1-C6), (a), (b) denote respectively independently 0-4 integers. R<3>, R<4> indicate either of a hydrocarbon group (C1-C6) or aryl group. R<8> in the formula VI is an org. group contg. at least one kind selected from vinyl, amino, imino and epoxy and R<9> is hydrogen, hydrocarbon group (C1-C6) and hydrogen halide group (C1-C6), R10 is a hydrocarbon group (C1-C5), acyl group (C1-C4), etc., (a) is 0, 1 or 2 and (b) is 0, 1 or 2 in which a+b<=2. |
