Abstract
There is provided a decorated sheet having a good adhesiveness with a molding resin regardless of a pattern of a colored part. A decorated sheet comprising: a transparent layer coating on the entire surface of a thermoplastic substrate sheet or at least in the areas of said substrate sheet having no coloring layer formed, said transparent layer coated by a transparent ink with as common varnish composition as the ink for coloring layer formation, and an adhesive layer formed as the outermost layer of said decorated sheet on the side provided with the colored layers of the substrate sheet. A molded article is fabricated by integrating the decorated sheet with a molding resin.

A decorated sheet on which a coloring layer is formed by printing on a substrate sheet made of thermoplastic resin, wherein the decorated sheet comprises:
- said substrate sheet;
- a transparent layer formed in areas where the coloring layer is not formed or formed on an entire surface of the substrate sheet on a side where said coloring layer is formed, wherein the transparent layer and the coloring layer both comprise a a varnish composition of a polyester polyol based resin and isocyanate;
- and
- an adhesive layer formed on both the coloring layer and the transparent layer on the side of the substrate sheet where the coloring layer is formed,
- wherein the adhesive layer is in direct contact with the coloring layer, and
- wherein the adhesive layer is made of polyethylene or polypropylene of a molecular weight of 10,000 to 150,000 with a maleic acid modification ratio of 0.3 to 10%.
A molded article fabricated by integrating a decorated sheet with a synthetic resin containing at least one of polypropylene or polyamide by film insert molding, the decorated sheet on which a coloring layer is formed by printing on a substrate sheet made of thermoplastic resin, wherein the decorated sheet comprises:
- a transparent layer formed in areas where the coloring layer is not formed or formed on an entire surface of the substrate sheet on a side where the coloring layer is formed, wherein the transparent layer and the coloring layer both comprise a varnish composition of a polyester polyol based resin and isocyonate;
- and
- an adhesive layer formed on both the coloring layer and the transparent layer on the side of the substrate sheet where the coloring layer is formed,
- wherein the adhesive layer is in direct contact with the coloring layer, and
- wherein the adhesive layer is made of polyethylene or polypropylene of a molecular weight of 10,000 to 150,000 with a maleic acid modification ratio of 0.3 to 10%.
