Abstract: Provided is a manufacturing method of a stainless steel sheet having etching patterns. The method includes: coating a coating composition on a stainless steel sheet to form a coating layer; and forming a matte coated film layer, having an etching effect, on the coating layer. The coating composition comprises: 10 to 30 wt% of a silane-based compound, 0.5 to 6 wt% of an organic acid, 0.1 to 3 wt% of a vanadium compound, 0.1 to 3 wt% of a magnesium compound, and a remainder of a solvent.

Abstract: A method of manufacturing a transparent pattern printed steel plate includes forming a printed paint film layer by jetting transparent ink onto at least one surface of a steel plate, and curing the printed paint film layer with ultraviolet light to form a cured printed paint film layer. Further, a method of manufacturing a transparent pattern printed steel plate includes preparing a steel plate having a color painted film layer formed on at least one surface thereof, forming a printed paint film layer by jetting transparent ink onto the color painted film layer, and curing the printed paint film layer to form a cured printed paint film layer.
