Title:

GLASS LAMINATE AND METHOD FOR PRODUCING GLASS LAMINATE

Document Type and Number:

WIPO Patent Application WO/2023/162900

Kind Code:

A1

Abstract:

The present invention provides a glass laminate in which it is possible to clarify the boundary line between a glass substrate and a printed layer in plan view, and a method for producing a glass laminate. A glass laminate (10) according to the present embodiment comprises a glass substrate (11) having a first main surface (11A) and a second main surface (11B), and a printed layer (15) laminated on part of the second main surface (11B). In a plan view of the printed layer (15) as seen from the second-main-surface (11B) side, the PV value of an end portion (15A) of the printed layer (15) that forms a boundary line (17) with the second main surface (11B) is less than 20 μm. In a cross-sectional view of the printed layer (15), the printed layer (15) has an average thickness greater than 2.0, and the value obtained by dividing the thickness-direction distance by the horizontal-direction distance between two different points established on the end portion (15A) is 0.1 or greater.
