Claim:
1. A method of producing an injection-molded product, comprising: a three-dimensional security element fabrication step of fabricating a three-dimensional security element in which a micro-lens array and an image array are disposed on opposite surfaces of a base material; a primer coating step of forming a primer layer on the image array; a protective film affixation step of affixing an outermost layer of protective film onto a top surface of the micro-lens array, wherein the protective film is made of heat resistant material and protects the micro-lens array from heat and pressure applied in an injection process; an injection molding step of producing an injection-molded product having a predetermined shape using the three-dimensional security element via an in-mold injection process, wherein the protective film is attached to the surface of the micro-lens array during the injection molding step; and a protective film removing step of removing the protective film from the three-dimensional security element.
