Document Type and Number:
WIPO Patent Application WO/2003/029160
Kind Code:
A1
Abstract:
A method for producing a glass sheet with a ceramic colored layer which involves forming, on the glass sheet (1), a laminate (4) comprising a colored layer (2) containing a low melting point glass powder and a heat−resistant pigment powder and contacting with the glass sheet and a releasing layer (3) containing a low melting point glass powder, followed by firing, wherein the low melting point glass powder in the colored layer (2) has a Bi2O3&sol SiO2 mole ratio of 0.275 or less, and the low melting point glass powder in the releasing layer (3) contains SiO2 and Bi2O3 in a Bi2O3&sol SiO2 mole ratio of more than 0.275 and precipitates crystals when it is fired as described above.
