NOVELTY - Metallic ink comprises 15-25 pts. wt. aqueous polyurethane resin, 35-50 pts. wt. aqueous acrylic resin, 1-10 pts. wt. glycerol monostearate, 5-10 pts. wt. ethanol, 3-8 pts. wt. chitosan-graphene composite, 3-8 pts. wt. auxiliary agent, 15-25 pts. wt. metal pigment, 3-8 pts. wt. hollow glass beads, 1-2 pts. wt. walnut shell powder, 1-5 pts. wt. dimethyl silicone oil and 1-5 pts. wt. deionized water. USE - Metallic ink. ADVANTAGE - The metallic ink is high temperature resistant. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing metallic ink, which involves: (A) mixing glycerol monostearate, ethanol and deionized water; (B) stirring and adding aqueous polyurethane resin, aqueous acrylic resin and dispersing the mixture; (C) milling and adding chitosan-graphene composite for 30-40 minutes; and (D) adding the remaining raw materials and uniformly stirring to obtain metallic ink.
