The present invention relates to a holographic pattern film production process and its holographic pattern membrane and system in the process. The holographic pattern film production process in the present invention is as follows: 1.1 Vapor-deposit the information transfer layer in the base film surface with the holographic pattern to obtain the transfer film; 1.2 Coat the adhesive layer on the information transfer layer or the foil film layer and composite the transfer film and the foil film. The described adhesive layer is an acrylic resin or a modified acrylic resin, an urethane resin or a modified polyurethane resin, an epoxy resin or a modified epoxy resin, or the copolymer / mixture of the above substances; 1.3 Peel off the base film to get the holographic pattern film, with the characteristics below: the trench structure of the holographic pattern on the described base film surface is copied to the information transfer layer. The present invention utilizes the coating process to form the holographic pattern film, thus the production cost can be greatly reduced and the production efficiency can be improved. |
