Abstract: A method of manufacturing a synthetic leather formed with a pattern includes a mixing step (A) in which at least a first material and a second material are properly mixed in proportion into a mixture; a first coating step (B) in which the mixture is coated on a substrate to form a blocking layer; a printing step (C) in which a determined pattern is printed on the surface of blocking layer to form a pattern layer; and a second coating step (D) in which at least the mixture is coated on the pattern layer to form a surface layer, thereby a product being finished. Thus, the pattern layer may be sandwiched between the blocking layer and the surface layer, which prevents the pattern layer contacting the substrate or outside from fading in color and shedding off and prevents the child from eating, by accident, the fall-off pattern layer.
