PROBLEM TO BE SOLVED: To provide a decorative ceramic sheet which is excellent in adhesion to a paint film and appearance while securing enough non-combustibility.SOLUTION: A decorative ceramic sheet has an organic paint film layer having an undercoat layer, a colored layer, and a clear layer in this order on the surface at least on one side of a ceramic substrate. In the decorative ceramic sheet, (a) the undercoat layer is surface-polished, and its film thickness is 5-100 μm, (b) the film thickness of the colored layer is 5-40 μm, (c) the clear layer is composed of a solvent clear layer which is applied by a roll coater and of 1-15 μm and a UV clear layer and has a total film thickness of 30-100 μm, and (d) the gross heating value by a cone calorimeter exothermic test is 8 MJ/mor less. |
