Method of forming multilayer coating film made from natural material

Disclosed are a multilayer coating film made from a natural material and a method of producing the same. The multilayer coating film may be produced by forming a multilayer coating film through formation of a color coating film for providing adhesion and color to a cork on the cork material and a clear coating film for realizing texture and supplementing properties on the color coating film. As such， the multilayer coating film may be made from a natural material to diversify the color and gloss of cork as a natural material， to additionally increase marketability of an interior material and provide various appearance， to prevent discoloration due to light (e.g. UV light.) and water permeation， and to enhance durability against abrasion， scratches and the like.
