METHOD OF PRODUCING COATED AND PRINTED GLASS SHEET Russian patent published in 2020 - IPC C03C17/34 

FIELD: glass.

SUBSTANCE: invention relates to glazing and can be used as a building material for glazing facades of a building. Disclosed is a method of producing glass sheet (1) with coating and printing (1), including at least the following stages: a) preparing glass substrate (2) with metal-containing coating (4) on at least one first surface (3.1) and a polymer protective layer (5) of thickness d on metal-containing coating (4), b) removing polymer protective layer (5) in first region (6) using carbon dioxide laser, c) removing metal-containing coating (4) within first region (6) only in second region (9) by means of solid-state laser, so that edge zone (10) is formed, in which metal-containing coating (4) is undamaged and in which polymer protective layer (5) has been removed at step b), d) applying ceramic paint (7) only in first region (6), e) heat treatment of glass sheet (1) at > 600 °C, wherein polymer protective layer (5) is removed from entire first surface (3.1) and ceramic paint (7) migrates in edge zone (10) into metal-containing coating (4) and binds with first surface (3.1) of glass sheet (1).

EFFECT: expansion of arsenal of technical means of application of coating on glass substrate.
