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.

Claim 1
Independent Claim 115 words
A metallized plastic molding, which comprises: (a) a plastic substrate, (b) a primer layer having a gel percentage of at least 80% and a swelling degree of not more than 20%, which is formed by curing a deposited primer forming material which comprises a mixture of a compound (A) having a molecular weight of at least 150 and less than 450 and containing at least two polymerizable unsaturated groups in one molecule and a compound (B) having a molecular weight of 450-2000 and containing at least two polymerizable unsaturated groups in one molecule in a weight ratio (A)/(B) of 1/9-9/1, on a surface of said substrate and (C) a metallic film on said primer layer.
Claim 2
Dependent Claim 115 words
A metallized plastic molding, which comprises: (a) a plastic substrate, (b) a primer layer having a gel percentage of at least 80% and a swelling degree of not more than 20%, which is formed by curing a deposited primer forming material which comprises a mixture of a compound (A) having a molecular weight of at least 150 and less than 450 and containing at least two polymerizable unsaturated groups in one molecule and a compound (B) having a molecular weight of 450-2000 and containing at least two polymerizable unsaturated groups in one molecule in a weight ratio (A)/(B) of 1/9-9/1, on a surface of said substrate and (C) a metallic film on said primer layer.
Claim 3
Dependent Claim 35 words
The metallized plastic molding of claim 1, wherein said compound (A) is the condensation product of a compound having at least two hydroxyl groups in one molecule and a polymerizable monomer having a carboxyl group.
Claim 4
Dependent Claim 40 words
The metallized plastic molding of claim 1, wherein said compound (B) is the addition product of a compound having at least two epoxy groups in one molecule and a polymerizable monomer having carboxyl groups prepared by a ring-opening esterification reaction.
Claim 5
Dependent Claim 68 words
The metallized plastic molding of claim 1, wherein the primer layer is formed by curing a primer forming material comprising a mixture of at least one compound having a molecular weight of 150-2000 and containing at least two polymerizable unsaturated groups in one molecule and a leveling agent which is a surfactant in an amount of 0.01-10% by weight of the total amount of said primer forming material.
Claim 6
Dependent Claim 76 words
The metallized plastic molding of claim 1, wherein the primer layer is formed by curing a primer forming material comprising a mixture of at least one compound having a molecular weight of 150-2000 and containing at least two polymerizable unsaturated groups in one molecule and a leveling agent selected from the group consisting of fluorine containing monomers and silicone compounds in an amount of 0.01-10% by weight of the total amount of said primer forming material.
