Is preferably 10 to 70% by mass, more preferably 20 to 50% by mass. A high modulus polyurethane resin having a 100% modulus of 300 kg or more has a very high coagulation rate during wet coagulation, so that the surface smoothness of the polyurethane resin solution immediately before coagulation is maintained as it is after coagulation, and surface properties suitable for printing It seems to give. If the amount of the high modulus polyurethane resin is less than 10% by mass, sufficient surface coagulation may not be obtained, and excellent surface smoothness may not be achieved. If it exceeds 70% by mass, the modulus of the whole resin becomes too high, and the surface smoothness may be reduced due to molding shrinkage. Further, the texture may be hard, which is not preferable. As described above, the surface smoothness immediately after coagulation mainly depends on the coagulation characteristics of the polyurethane resin having a high modulus, but the modulus of the entire system is preferably set so that molding shrinkage is difficult. Therefore, the compounding ratio of the high modulus polyurethane resin is preferably 70% by mass or less, and the 100% modulus of at least one of the other polyurethane resins mixed with the high modulus polyurethane resin is 100K.
