Transfer sheet for polyamide articles
First Claim
1. A heat release decalcomania for polyamide articles comprising a backing material layer, a design layer comprising a film forming component and a coloring pigment, and an adhesive layer on said design layer, said adhesive layer consists essentially of (a) 30 to 90 parts by weight of nitrocellulose having a degree of nitration of from about 10 to about 14%, a degree of polymerization of from about 40 to about 450 and a specific gravity of from about 1.5 to about 1.6, and (b) 70 to 10 parts by weight of a member selected from the group consisting of phthalic ester plasticizers, fatty acid ester plasticizers, phosphoric ester plasticizers, epoxy plasticizers, alkyd resins, maleic acid resins and mixtures thereof.

Abstract
A transfer sheet which is used for transferring designs on to the surface of articles made of polyamide resin. The transferred design on the polyamide articles are excellent in appearance, durability and adhesiveness to the polyamide surfaces. The transfer sheet is basically composed of a backing material, a design layer and an adhesive layer and the invention is characterized in that said adhesive layer contains a varnish which is composed of: (A) nitrocellulose and (B) one member or a mixture of more members selected from the group consisting of phthalic ester plasticizers, fatty acid ester plasticizers, phosphoric ester plasticizers, epoxy plasticizers, alkyd resins and maleic acid resins.
