The present invention is to establish a process for production of highly durable organic silicon-based coatings with satisfactory adhesive property on polyolefin resins. A polyolefin resin, wherein after hydrophilic treatment of the surface of the polyolefin resin it is coated with a coating solution containing a silicon compound or its hydrolysate with an organic functional group represented by general formula (1): R1 n Si(R2)4-n (where R1 is an organic functional group with a methacryloxy group, R2 is one or a plurality of hydrolyzable groups selected from among alkoxyl groups, acetoxyl groups and chlorine, and n is an integer of up to 3), and then dried to obtain a primary coating, over which a silicon dioxide coating is formed. Alternatively, the primary coating may be obtained by coating and drying a coating solution containing a plurality of different silicon compounds or their hydrolysates from among silicon compounds and their hydrolysates with an organic functional group represented by general formula (2) : R3 n Si(R2)4-n (where R3 is an organic functional group with a functional group selected from among methacryloxy, vinyl, allyl and amino groups, R2 is one or a plurality of hydrolyzable groups selected from among alkoxyl groups, acetoxyl groups and chlorine, and n is an integer of up to 3).
