Abstract
Disclosed is an outdoor color-changeable film with self-recovering properties that includes a transparent base film; a hard-coating pearl layer formed on an outer surface of the transparent base film and includes pearl particles dispersed in a hard-coating agent; a first adhesive layer disposed on another surface of the transparent base layer; a color base film disposed on the first adhesive layer to laminate the color base film onto a surface of the hard-coating pearl layer; a second adhesive layer coated on a surface of the color base film; and a release film detachably laminated onto the second adhesive layer. The self-recovering properties include water repellency, anti-fouling, and antibacterial functions, ultraviolet ray blocking ability, and use in various fields due to a long-lasting film property and an insecticidal effect.
