Abstract
A method of manufacturing an identification card whereby information is printed on a sheet of plastic material. A raised pattern is formed on a different sheet of material to create a holographic image. The resultant raised pattern sheet is attached to the surface of the sheet of plastic material by pressure sensitive adhesive. The surface of the plastic material is overlaminated with a transparent layer to form a sandwich and heat and pressure is applied to fuse overlaminated layers. The pattern sheet has a high melting point so that the image is viewed as three-dimensional through an overlaminated layer.
Claims2
A method of manufacturing an identification card incorporating an image viewable as three-dimensional comprising the steps of:
- printing information on a sheet of plastic material;
- forming a raised pattern on a sheet of material different from said plastic material to create a holographic image viewable as three-dimensional;
- coating said raised pattern sheet with an adhesive which promotes bonding to said plastic material;
- attaching a pressure sensitive adhesive to one side of the coated and raised pattern sheet, the pressure sensitive adhesive extending over less than half the surface of said one side;
- placing said coated and raised pattern sheet on one surface of said sheet of plastic material so that said pattern sheet is attached to said sheet of plastic material by said pressure sensitive adhesive;
- overlaminating such surface of said plastic material with a transparent plastic layer to form a sandwich;
- and
- applying heat and pressure to said sandwich to fuse said overlaminating layers to said sheet of plastic material, said coated and raised pattern sheet having sufficiently higher melting point so that the image remains and is viewable as three-dimensional through an overlaminated layer and so that said coated and raised portion is bonded on said one side to said plastic sheet.
