Field of the Invention The present invention relates to a method of making the same, and more particularly to a suitable shape for visualizing a surface. [Prior Art] Typically, artificial leather for manufacturing gloves The uranium is formed by mixing the general fiber fibers to form a non-woven fabric, refilling to form a base fabric, and then coating the polyurethane surface with the elastic and leather lines on the surface of the base fabric with a release paper, and patterning the paper with a color pattern. The printed pattern of the printing wheel converts the paint to the printing wheel and can only print a single stereo effect at a time, especially in the case of water washing. The application of the laser beam is very wide, and the energy of the radiation beam can be utilized to distinguish the radiation beam without being washed by water. Therefore, how to create a layered color through high-energy excitation is provided. [The present invention aims to provide a laser. The artificial leather of the pattern forming layer and the artificial leather using the high energy excitation radiation beam scanning type and the manufacturing method thereof. , clothing, shoes, purses and the like, microfiber or general fibers and ultrafine polyurethane (PU) compositions are applied by grinding or embossing or resin bonding, and forming a table Work leather. The surface pattern of artificial leather is made by a technique in which the surface is engraved on the surface of the artificial leather. However, the color, and the pattern is difficult to have a multi-layer or sun exposure, which will gradually fade the pattern, including engraving on metal or non-metal, and has the advantage of being scored or brewed to make the pattern fade. The radiation beam makes the artificial leather surface visible, which is worthy of research and development. A person with a laser pattern layer
