[Problem] To provide a synthetic resin leather that has excellent flame retardancy, is flexible, has excellent surface scratch resistance, can be welded with a high-frequency welder, and does not spread seams. SOLUTION: A flame retardant synthetic resin leather in which a thermoplastic polyurethane resin layer is provided on at least one side of a base fabric which has been flame retardant processed using a nitrogen-phosphorus flame retardant. The nitrogen-phosphorous flame retardant is preferably a flame retardant selected from condensed ammonium phosphate, condensed melamine phosphate, condensed ammonium amide phosphate and carbamate phosphate. The thermoplastic polyurethane resin layer comprises a mixed resin layer of 50 to 95% by weight of thermoplastic polyurethane having a Shore A hardness of 65 to 90 and 50 to 5% by weight of acrylic soft resin having a Shore A hardness of 50 to 80, And the thing whose Shore A hardness of a mixed resin layer is 60-80 is preferable. Moreover, it is preferable that said thermoplastic polyurethane-type resin contains 1 or more types of flame retardants chosen from the phosphate ester type | system | group flame retardant and the nitrogen-type flame retardant. |
