Patent ID: 7520216

Claim:
A method for manufacturing an aluminum-coated laser hologram paper, the method comprising acts of: coating a working face of a paper substrate with a first water-based varnish layer; thermally compressing the first water-based varnish layer; steam coating an aluminum film on the water-based varnish layer by vapor deposition; coating a water-based resin film on the aluminum film; printing an ink layer on the water-based resin film to form patterns; coating a second water-based varnish layer on the ink layer; thermally compressing the second water-based varnish layer; and compression molding the paper substrate to perform laser grains on the water-based varnish layer; wherein the water-based varnish layer comprises 42±2 wt% acrylic copolymer, 3±1 wt% soya bean oil (lecithin) and 55±1 wt% water.
