Abstract
Glass bottles, suitable as containers for drinks, such as beer and fruit juice, are coated with a single layer of a thermally cured material formed of a powdery composition comprising a mixture of (i) a blocked organic polyisocyanate and (ii) a hydrolyzed ethylene-vinyl ester copolymer and/or a carboxyl-modified version of said hydrolyzed copolymer. The coated bottles are highly effective in the prevention of scattering of glass fragments in the event of breakage and excellent in clarity, alkali resistance, abrasion resistance, scratch resistance and weathering quality.
