Abstract
A silver-plated laminated body which is highly durable and can easily be manufactured has an undercoat layer, a silver-plated layer, a lower topcoat layer, and an upper topcoat layer which are successively disposed in the order named on a base of plastics. The undercoat layer comprises a coating film which is mainly made of an alkyd resin that is free of a catalyst. The silver-plated layer is formed by a silver mirror reaction. The lower topcoat layer comprises a coating film which is mainly made of polyester polyol. The upper topcoat layer comprises a coating film which is mainly made of polyester polyol containing a di-isocyanate compound as a hardener. The lower topcoat layer contains a colorant.
Claims8
A silver-plated laminated body comprising:
- a base;
- an undercoat layer disposed on said base and comprising a coating film which is mainly made of an alkyd resin that is free of a catalyst;
- a silver-plated layer disposed on said undercoat layer and formed by a silver mirror reaction;
- a lower topcoat layer disposed on said silver-plated layer and comprising a coating film which is mainly made of polyester polyol;
- and
- an upper topcoat layer disposed on said lower topcoat layer and comprising a coating film which is mainly made of polyester polyol containing a di-isocyanate compound as a hardener.
A method of manufacturing a silver-plated laminated body, comprising the steps of:
- coating a surface of a base with a coating compound which is mainly made of an alkyd resin that is free of a catalyst, and drying the coating compound into an undercoat layer;
- coating a surface of said undercoat layer with an aqueous solution containing silver and a reducing agent, and drying the aqueous solution and the reducing agent into a silver-plated layer by way of a silver mirror reaction;
- coating a surface of said silver-plated layer with a coating compound which is mainly made of polyester polyol and drying the coating compound into a lower topcoat layer;
- and
- coating a surface of said lower topcoat layer with a coating compound which is mainly made of polyester polyol containing a di-isocyanate compound as a hardener, and drying the coating compound into an upper topcoat layer.
