The method for producing an image molded product according to the present invention comprises a character / image information pattern on at least one side of an image molded paper material based on stretched paper having a breaking elongation of 10% or more in the vertical direction and 10% or more in the horizontal direction. Is displayed on the image forming paper material along the character / image information pattern so that the shape corresponding to the character / image information pattern is uneven. If there is something like a stick without using it, anyone can easily make it.

An example of the best mode for carrying out the manufacturing method of the engaging Ru images moldings and picture moldings to the present invention will be described below.

  First, an embodiment of an image forming paper material will be described. The stretched paper serving as the base of this example has a breaking elongation specified in JIS P 8113 of 10% or more in the vertical direction and 10% or more in the horizontal direction.

  Examples of such stretched paper include stretched paper that has been imparted with high stretch properties by kulpack processing, crepe processing, or the like. In particular, as disclosed in Japanese Patent Publication No. 11-509276, a hard roll made of a hard substance and having ribs on its surface in the circumferential direction and rotating at a higher speed than the other, and a smooth roll made of a soft substance. Stretched paper obtained by shrinking wet paper between a pair of rolls made of soft rolls having a smooth surface and rotating at a slower speed than the other, or as disclosed in Japanese Patent Application Laid-Open No. 2004-3071 In addition, a roll along the circumferential direction of the roll is provided with a pair of press rolls consisting of a hard roll provided with a predetermined interval in the roll width direction and a soft roll with a flat roll circumferential surface, The soft roll is rotated at a lower peripheral speed than the hard roll (preferably, the soft roll has a peripheral speed of 0.95 to 0.5 with respect to the peripheral speed 1 of the hard roll). Shrinkage The location, giving shrinkage the paper sheet paper in water and passed through a 20% to 50% of the paper sheet, it is preferable to use a stretch paper obtained by subsequent drying.

The basis weight of stretch paper for use in the present ^invention, the range of 50g / ^{m 2} ~300g / m 2 is preferred. If the basis weight is less than 50 g / m ² , the strength is insufficient and breakage occurs when the irregularities corresponding to the image information are arbitrarily adjusted. On the other hand, if the basis weight exceeds 300 g / m ² , the stress when arbitrarily adjusting the unevenness corresponding to the image information is undesirably high.

  The stretched paper used in the present invention may contain synthetic fibers as long as it does not affect the stretch properties and the like, but is preferably composed of 100% natural pulp. As natural pulp, normal paper raw materials such as softwood or hardwood wood fibers, bast fibers such as cocoons and cocoons, non-wood fibers such as bagasse and kenaf, cotton fibers, waste paper, etc. can be used. It is preferable to use wood fiber chemical pulp, mechanical pulp, deinked pulp and the like.

  The stretched paper used in the present invention may be smoothed to the extent that it does not affect stretch properties and the like in order to improve printability. Smoothing may be performed by a device usually used for smoothing paper such as super calendar processing and soft calendar processing.

  In addition, among the possible uses of the molded image product to be molded, for example, when used for things that may be posted outdoors such as posters and billboards, for the purpose of imparting water resistance and the like, Although one having one or more resin layers on one or both sides of stretched paper can be used, in this case as well, it is essential that the elongation at break specified in JIS P 8113 is 10% or more in both length and width.

  In this case, the resin to be used is preferably a thermoplastic resin, specifically, high density polyethylene (HDPE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE), single site linear low Examples include density polyethylene (polyolefin resin such as linear low density polyethylene (SS-LLDPE) synthesized using a single site catalyst, random polypropylene, homopolypropylene, polyester resin, polystyrene resin, etc.).

  As means for providing the resin, general methods such as extrusion coating lamination, wet lamination, dry lamination, and the like are used. In general, it is known that a paper substrate provided with a resin layer has a small environmental load during combustion. Therefore, an image molded product provided with a resin layer in this way is also natural pulp 100. As with the%, the environmental impact is small.

  Image information such as various pictures, photographs, characters, and figures is displayed on image forming paper materials based on stretched paper by a general method such as handwriting, printing, copying, and the like.

  Among the image forming paper materials based on stretched paper, in the case where a resin layer is provided on stretched paper, the order in which the resin layer and image information are provided on the stretched paper may be any order. That is, the image information may be provided in advance before the resin layer is laminated on the stretched paper, the image information may be provided after the resin layer is laminated on the stretched paper, or the film provided with the image information is wet. It may be bonded to stretched paper by lamination or the like. However, regardless of the method, the above-described general method is used as the image information display method itself.

  As described above, the base stretch paper has a breaking elongation specified in JIS P 8113 of 10% or more in the vertical direction and 10% or more in the horizontal direction. If it is less than 10%, breakage or cracking occurs during molding. Thus, the shape of the molded product is limited, and a complicated molded product cannot be obtained.

The image molding sheet material described above, the addition of pressing by a press or the like from one surface thereof, elongation pressed portion, so that can be given a concave convex shape corresponding to the information of the character-image on its surface, three-dimensional It can be used as a raw material for image moldings expressed in JIS P 8113, which is the base stretch paper, and has a specified elongation at break of 10% or more in the vertical direction and 10% or more in the horizontal direction. It is possible to obtain a complicated molded product that is not broken or cracked.

Furthermore, the image molded sheet material, painting, photograph, character, image information of FIG like handwriting, printing, copying, etc., can be displayed in a general way, pre Me picture, pictures, characters, FIG. By displaying the image information such as the above, it is possible to easily make unevenness corresponding to the displayed character / image information, which is convenient as an image forming paper material.

Next, an embodiment of a three-dimensional image molding using an image molding paper material will be described. Image molded product obtained by three-dimensional with the image molded sheet material of the present example, along the character-image information pattern in the image molding sheet material character-image information pattern on at least one surface is displayed, character -The shape corresponding to the image information pattern is uneven.

  In addition to the method of mechanically molding the mold into a shape corresponding to the image information with a molding machine having a mold conventionally used for molding plastics, the method of attaching unevenness is a rod shape for personal use A method can be used in which an object is pushed into a shape corresponding to a three-dimensional structure by human power.

In addition, the three-dimensional image molding using the image molding paper material gives irregularities to a desired shape using the image molding paper material on which no character / image information pattern is displayed, and the resulting irregular shape pattern of arbitrary to, may be the one wearing the color.

  In the image molded product, the ratio of the surface area of the image molded product to the area of the information pattern is preferably 105% to 150%. If the ratio of the surface area of the image molding to the area of the information pattern is less than 105%, there is no force as a three-dimensional image, and if it exceeds 150%, cracks and breaks frequently occur due to insufficient elongation of stretched paper, resulting in poor appearance of the molding. It is not preferable.

Further, the image molding is enriched in image expression by forming an image molding by combining a plurality of image moldings. In this case, two or more of the same type of image moldings to be combined, or two or more different types of image moldings may be used. Production method of each picture moldings combining these, along said text and image information pattern in the image molding sheet material to one surface character-image information pattern is displayed, the character-image information pattern as long as it is produced by a process giving an uneven shape corresponding to, in particular restrictions have greens. Image molded article obtained as this, the image representation is richer, for example, it is optimal for display or the like.

Next, an embodiment of the method for producing the image molded product using an image molding paper material will be described. The method for producing an image molded product of the present example is an image molding paper material based on stretched paper having a breaking elongation specified in JIS P 8113 of 10% or more in the vertical direction and 10% or more in the horizontal direction, on at least one side. A character / image information pattern is displayed, and the shape corresponding to the character / image information pattern is made uneven on the image forming paper material along the character / image information pattern .
