The present invention is a synthetic leather having a base cloth (i), an intermediate layer (ii) and a skin layer (iii). The intermediate layer (ii) is composed of an amino group containing an anionic group at a concentration of 0.35 mmol / g or less An ester resin (A) and an aqueous medium (B) of an aqueous urethane resin composition (C), wherein the urethane resin (A) is a polyol containing an anionic group ( a1-1) The reactant of polyol (a1) and aromatic polyisocyanate (a2), the skin layer (iii) is composed of an aqueous amine containing a urethane resin (X) and an aqueous medium (Y) It is formed by a urethane resin composition (Z), wherein the urethane resin (X) is a polysiloxane (b1), a reactive polysiloxane (b2) having a functional group reactive with an isocyanate group And polyisocyanate (b3) as a necessary raw material reactant. |
