INJECTION-MOLDED PRODUCT HAVING THREE-DIMENSIONAL SECURITY ELEMENT AND PRODUCTION METHOD THEREFOR

WIPO Patent Application WO/2013/115587

A1

The present invention relates to a method for producing a three-dimensional security element and an injection-molded product having the three-dimensional security element and, more specifically, to a method for producing a three-dimensional security element suitable for an in-mold process by using a moiré expansion phenomenon, and for producing an injection-molded product to which the three-dimensional security element is applied. The present invention according to one embodiment comprises a three-dimensional security element and an injection-molded product having the three-dimensional security element, wherein the three-dimensional security element further comprises: a micro lens array to which various types of lenses can be applied; an image array; a primer layer for facilitating adhesion; and a protection film for protecting the three-dimensional security element from heat and pressure. According to the configuration above, the present invention can implement three-dimensional effects, such as a latent image effect, a floating effect, and an inverted parallex effect, wherein an effect is determined by a period rate and a matching angle between the micro lens array and the image array.
