ABSTRACT:
The present invention relates to an artificial grain leather having different color spot groups comprised of ultra fine fibers, in which at least one side of the fibrous substrate has two types of colors differing in hue and/or lightness value and being covered with transparent resin layers.
The present invention produces a three-dimensional surface effect and a grain pattern effect, and is recognized as consisting of a mixture of ultra fine fibers each being quite different in color from the next, though providing the appearance of a single color from a distance, and producing a subdued and rich appearance as a result of the integration of colors by the color of a coating layer.
