ABSTRACT:
A glass article is decorated with a thermoplastic ink which contains no frit. A finely divided heat fusible polymeric coating material is applied to the article over the ink. The article is heated to a temperature at which the particles of coating material fuse to form a smooth continuous film over the ink while the latter is in melted, semi-liquid condition. The melted ink diffuses into (but not through) the polymer film over it, thereby forming a melt-melt bond. The polymeric film imparts a serviceability to the ink which it would not otherwise display.
