Patent ID: 7361405

Claim:
A coated glass or glass-ceramic panel exposed to a high heat load in operation, said coated glass or glass-ceramic panel comprising a transparent, colorless glass or glass-ceramic panel having a surface; a full-surface or partially-covering, visually dense, high-temperature-stable coating on said surface of said transparent, colorless glass or glass-ceramic panel, said high-temperature-stable coating having a no melt-reaction zone between the coating and the glass or glass-ceramic panel at said surface of said panel; in which said high-temperature-stable coating comprises an organic solvent-containing SiO 2 -based sol-gel network structure, filling material particles contained in said sol-gel network structure, and at least one color-imparting inorganic pigment contained in said sol-gel network structure; in which said filling material particles comprise at least one member selected from the group consisting of pyrolytically deposited SiO 2 particles, TiO 2 particles, talc particles, calcium carbonate particles and barium sulfate particles; in which said at least one color-imparting inorganic pigment optionally comprises a glitter pigment; and in which said sol-gel network structure is made from a silicon-containing precursor, water, and at least one organic solvent, said silicon-containing precursor comprising a silane or siloxane.
