Abstract
Plastics articles, such as plates, bowls, cups and the like which are for containing foodstuffs and are useable in freezers, and microwave and conventional cooking ovens, are of crystalline polyethylene terephthalate rendering them suitable for such purposes, and the articles are decoratively printed using inks containing thermoplastic resin binders and pigments, and the pigment is keyed firmly to the articles to prevent ready removal therefrom by abrading by heating the applied ink by means of a naked flame quickly to bring the resin binder up to its melting point so that the binder and article become bonded together keying the pigment to the article.
