PROBLEM TO BE SOLVED: To provide pattern paper which is excellent in design property, which achieves plural kinds of gradation expression, which exhibits different watermark patterns according to a visible angle of an observer, and which has flexible and high-grade appearance.SOLUTION: Pattern paper 10 is formed by laminating three-paper layers of paper layers 11, 12, 13 which have light transmissivity, and integrating them. The pattern paper has a laminate structure in which, only the paper layers 11, 12 having watermark patterns 11W, 12W are laminated by two layers or more layers. The watermark patterns 11W, 12W comprise a material lack part on which, a formation material of the paper layer does not exist, or a thin layer part whose thickness is thin, relative to its peripheral part. In plan view, parts 20 in which, plural watermark patterns 11W, 12W which are disposed on different positions in a thickness direction of the laminate structure, are overlapped, and parts 21, 22 in which the plural watermark patterns are not overlapped, exist. Preferably, the paper layer 12 disposed inside of the thickness direction has deeper color than color of the paper layers 11, 13 disposed on outside of the thickness direction.SELECTED DRAWING: Figure 1 |
