Zusammenfassung: | A hard-coated material having a substrate coated with a wear resistant and easily removed film is provided. The film comprises laminated alternately in succession, a lower layer-A having a composition of formula TivM1-v(CxNyOz) and an upper layer-B having a composition of formula TivCrwM1-v-w(CxNyOz). At least two lamination units are provided and the ratio in thickness of a singularity of the layer-B to a singularity of the layer-A is at least 2. The thickness of a singularity of the layer-A is within the range of 0.1 to 3μm both inclusive, the thickness of a singularity of the layer-B is within the range of 1 to 10μm both inclusive, and the total thickness of a plurality of the layers-B is at least 5 μm. |
