Abstract
Abstract A metallized plastic molding comprises a plastic substrate, a primer layer having a gel percentage of at least 80% and a swelling degree of 20% or less deposited on said substrate and a metallic film deposited on the primer layer. The metallized plastic molding is prepared by coating a plastic substrate with a primer forming material containing at least one compound having a molecular weight of 150 - 2000 and containing at least two polymerizable unsaturated groups in one molecule, curing the primer forming material so that it has a gel percentage of at least 80% and a swelling degree of 20% or less to form a primer layer and then depositing a metallic film layer by a dry type method on the primer layer.
