<p>PROBLEM TO BE SOLVED: To obtain an openwork forgery-preventive paper, the feed and delivery at printing of which is easy, which is hard to develop wrinkles and has high surface strength by a method wherein a minute inorganic powder-containing propylene-based resin uniaxially oriented film layer is provided on the front and rear sides of a propylene-based resin biaxially oriented film layer. SOLUTION: This openwork forgery-preventive paper has a support layer, which is a laminated oriented matter consisting of a base material layer made of a propylene-based resin biaxially oriented film layer and propylene-based resin uniaxially oriented film layers provided on the front and rear sides of the biaxially oriented film layers, and has the opacity defined by JIS P-8138 or 50-100% and the density defined by JIS P-8188 satisfying 0.70-1.4g/cm<3> and has an engraving, which is applied to the depth of the engraving coating layer or to the depth of the uniaxially oriented matter of a support. When transmitted light is applied from the rear side of the laminated oriented matter under the condition that image parts 5 are engraved and shadow parts 6 are engraved to the uniaxially oriented film layer 1a or 1b of the support 1 at both the sides of each image part, images having clear shadows can be vividly recognized visually.</p> |
