The present invention provides a novel and improved synthetic resin leather comprising a substrate and a synthetic resin layer, wherein it has reduced difference of elongations between in a longitudinal direction and in a transverse direction, desirable thickness, no melting during combustion and excellent feelings and good flame retardant property, which is suitable for use in general applications such as interior finishing materials and/or seats for automobile. More particularly, with respect of the leather of the present invention comprising a substrate 1 having both sides cross-knitted and a synthetic resin layer 2 attached to at least one side of the substrate 1, the substrate 1 is prepared by cross-knitting a first yarn 3 with 10 to 40 in count composed of one selected from single spun or mixed spun fibers made of rayon, cotton, polyester, nylon, acryl, urethane and a second yarn 4 with 50 to 300 in denier composed of one selected from crimpy long fiber filaments, thermoplastic elastomer long fiber filaments and polyurethane long fiber filaments; and knitting the both-sided cross-knitted fabric such that loops 6,6' made of the second yarn 4 are enclosed by loops 5,5' made of the first yarn 3, thereby making the loops 6,6' made of the second yarn 4 discontinuous in the longitudinal direction, the transverse direction, and/or on front and rear sides of the substrate 1.
