摘要:
A ceramic single layer-coated metal sheet having an excellent decorative property and a high weatherability, which comprises a metal substrate and a transparent ceramic layer formed on the metal substrate by a dry process such as physical vapor deposition or chemical vapor deposition, said transparent ceramic layer having a thickness of 0.05 to 5 .mu.m and a refractive index in the visible region of at least 2.0. A ceramic multiple layer-coated metal sheet having an excellent decorative property and a high weatherability is also disclosed, which further comprises a colored ceramic layer between the substrate and the transparent ceramic layer, the first layer being formed of at least one member selected from the group consisting of nitrides, carbides and carbonitrides of at least one element selected from the group consisting of Ti, Zr, Hf, Cr, Nb and Al and having a thickness of 0.1 to 1 .mu.m.
