1 and 2, the artificial leather sheet 100 according to an embodiment of the present invention includes a leather fabric layer 110, a cover layer 120, a film layer 130, and an embossing 140. .

The leather fabric layer 110 may be made of nonwoven fabric or knit. In this case, when the leather fabric layer 110 is made of a nonwoven fabric, the nonwoven fabric may be any one selected from the group consisting of polypropylene, polypropylene blend, polyethylene, polyethylene blend, ethylene vinyl acetate and ethylene vinyl acetate blend.

The cover layer 120 is laminated on the upper surface of the leather fabric layer 110 and has a first color. The label layer 120 may be formed of at least one of polyvinyl chloride (PVC), polyurethane (PU), and thermoplastic polyurethane (TPU).

The film layer 130 is stacked on the cover layer 120 and has a second color different from the first color. The film layer 130 may be attached to the top surface of the label layer 120 in a laminate method using heat and pressure. Alternatively, the film layer 130 may be formed on the top surface of the label layer 120 by a deposition process. For example, a urethane film may be used as the film layer 130.

The embossing 140 is a printed pattern formed by pressing the film layer 130 by high frequency pressing. The embossing 140 is formed in the film layer 130 as shown in FIG. 2, or alternatively, as shown in FIG. 3, high frequency compression is performed until some surfaces of the label layer 120 are exposed. It may be formed on the surface of the cover layer 120.

As described above, in the present embodiment, the film layer 130 is pressed by high frequency pressing in a state in which the film layer 130 having the second color different from the first color is laminated on the cover layer 120 having the first color. Through the embossing 140 is printed in the film layer 130 through the multi-color can be implemented.

Therefore, in the present embodiment, it is possible to impart an aesthetic sense through a two-tone effect, and as a result, it is possible to produce various designs.
