Pop screen methods in which three-dimensional representation is performed by foaming a pattern, and patterns are sprayed and laminated by using a 3D scanner or a spray robot. , Or a PU casting method in which a liquid polyurethane (PU) is put into a mold to express a three-dimensional pattern is applied.
More specifically, in the case of the pop screen method, the foaming resin is applied to the fabric, followed by hot air drying or natural drying at room temperature, and then the foamed resin is heated to foam to have a three-dimensional pattern. However, the above method has a problem that the work process is very complicated and the work time is very long.
In addition, since the operator takes a form in which the foamed resin is overlaid by hand, there is a difference in the expression of the design according to the skill of the operator, resulting in a difference in the finished quality, , There is a problem that the three-dimensional texture to be desired can not be sufficiently expressed.
In the case of the lamination method, a composition for forming a pattern is sprayed and laminated onto a surface from a nozzle using an apparatus having a drawing mechanism, and the composition is cured to form a stereoscopic display part. However, in the case of the above method, not only the injection and the laminating time take a long time but also the curing time of the pattern marked with three dimensions takes a long time, and the operation time is still long.

When a lamination film according to an exemplary embodiment of the present invention is laminated on a photo paper, a block pattern and a three-dimensional pattern according to photographic images printed on a photographic paper can be selected to give various stereoscopic effects and textures even if the same image is used.
When the laminating film according to one embodiment of the present invention is laminated on a glass such as a window, the stereoscopic effect and the texture of a regularized or irregular pattern are imparted to adjust the interior effect and the thickness of the laminating film to control the transmittance and haze .
When the laminating film according to an embodiment of the present invention is laminated on the screen display unit of the display device, a three-dimensional effect and texture are given to the displayed screen, and lamination of the same pattern of laminating films can exhibit different effects depending on illumination .
