Patent number: 10308547Abstract: The present invention relates to a hollow glass, such as a bottle, glass, flask or pot, consisting of a glass substrate having, on at least one portion of its outer wall, a hydrophilic organic coating, for instance based on polyvinyl alcohol crosslinked with at least one acid selected from citric acid, polyacrylic acid and poly(acrylic acid-co-maleic acid). In order to manufacture this hollow glass, a solution containing the ingredients for forming the coating and at least one solvent is applied to the glass substrate by spraying, dip-coating or, when the hydrophilic organic coating is a partial coating, by spraying onto the outer wall of the glass substrate on which a mask has been applied, or by screenprinting; the glass substrate coated with said solution is dried; and the substrate is cured thermally or by UV radiation or by electron beam. It is possible to use this hollow glass for revealing a pattern thereon when said hollow glass is removed from a cold storage zone.Type: GrantFiled: July 2, 2015Date of Patent: June 4, 2019Assignee: VERALLIA FRANCEInventors: Alix Arnaud, Fabio Foti, Maxime Chestier
