    摘要： The present invention discloses a coloring method of a natural leather and a colored natural leather using the same. The coloring method includes the steps of: putting the natural leather having a colored layer formed on one face thereof together with a releasing paper having an aqueous polyurethane layer and an adhesive layer sequentially coated thereon so that the colored layer and the adhesive layer are faced to be in contact with each other; and removing the releasing paper from the aqueous polyurethane layer. The colored natural leather includes an aqueous polyurethane layer; an adhesive layer formed on an upper surface of the aqueous polyurethane layer; a colored layer having various colors of pattern, formed on an upper surface of the adhesive layer; and a natural leather formed on an upper surface of the colored layer.
