MARKED COATED GLASS PLATE AND METHOD FOR PRODUCING SAME

摘要

This marked coated glass plate (1) contains: a glass plate (11) having a first principal surface (11a) and a second principal surface (11b) which face one another, and a first coating film (12) provided on the first principal surface (11a). Marks (111) are formed on the second principal surface (11b). The marked coated glass plate (1) may further contain a second coating film provided on the second principal surface (11b) of the glass plate (11). The first coating film (12) has a thickness of at least 1.5μm, and has an outer surface having a surface roughness (Ra(1)) not exceeding 1μm. The second coating film has a thickness not exceeding 0.3μm, and on the outer surface of the second coating film, the difference between the surface roughness (Ra(2A)) in the area in which marks (111) are formed and the surface roughness (Ra(2B)) in the area in which marks (111) are not formed is at least 1.5μm.
