Zusammenfassung:PROBLEM TO BE SOLVED: To provide a synthetic resin leather having flexibility and excellent surface scratch resistance, weldable with a high-frequency welder, having flame- retardance and free from the trouble of the expansion of seam. SOLUTION: This synthetic resin leather has a mixed resin layer composed of 40-95 wt.% copolymerized polyester resin and 60-5 wt.% soft acrylic resin on at least one surface of the substrate. The mixed resin layer may further contain 5-40 pts.wt. of an elastomer based on 100 pts.wt. of the mixed resin. The mixed resin layer is preferably compounded with a plasticizer. The plasticizer is preferably an aromatic carboxylic acid ester. A woven fabric, knit fabric or nonwoven fabric is used as the substrate. The substrate may be a soft foamed sheet or a laminate of a soft foamed sheet and a woven fabric, knit fabric or nonwoven fabric.
