<p>Provided is a base material having a thin film which has a high film density, high film hardness, excellent adhesiveness to the base material and that between composition layers, high durability and high rub resistance, and does not easily generate a crack and the like even on the flexible base material. The base material has a single layer film having a configuration wherein a high film density region is sandwiched from the both sides with regions wherein the film density thereof continuously lowers in the thickness direction. Alternatively, the base material has a multilayer film composed of such single layer films. The ratio between the maximum film density value and the minimum film density value of the single layer film is 1.03-1.5.</p> |
