The present invention is characterized by containing an anionic urethane resin (A) having a flow starting temperature of 100 ° C. or lower, a neutralizing agent (B), a carbodiimide crosslinking agent (C), and an aqueous medium (D). It provides an adhesive. The present invention also provides a synthetic leather having at least a substrate (i), an adhesive layer (ii) formed by the adhesive, and a skin layer (iii). The carbodiimide cross-linking agent (C) is 1,3-bis (1-methyl-1-isocyanatoethyl) benzene, 1,4-bis (1-methyl-1-isocyanatoethyl) benzene, and dicyclohexylmethane diisocyanate. It is preferable to use one or more polyisocyanates selected from the group consisting of as a raw material. |
