▎ 摘　　要

NOVELTY - Vehicle window film (100) comprises an adhesive layer (130) including an acrylic copolymer, a curing agent, and a solvent; a first poly(ethylene terephthalate) (PET) (141) layer disposed on the adhesive layer and including polyethylene terephthalate; a bonding layer (110) disposed on the first PET layer and including a urethane resin, a curing agent, a UV blocking agent, an IR blocking agent, and graphene; a second PET layer (142) disposed on the bonding layer (110) and including polyethylene terephthalate; and a hard coating layer (120) disposed on the second PET layer and including an acrylic resin and a photoinitiator. The IR blocking agent includes carbon, tungsten oxide (WO3) and antimony-doped tin oxide (ATO). USE - Vehicle window film. ADVANTAGE - The vehicle window film blocks heat from entering an interior, and dissipates the heat quickly through graphene, for increasing thermal insulation efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a laminated structure of the vehicle window film. 100Vehicle window film 110Bonding layer 120Hard coating layer 130Adhesive layer 141First poly(ethylene terephthalate) 142Second PET layer 200Release film
