To provide a water-based dry laminating adhesive composition for synthetic leather, to provide a method for producing a synthetic leather using the composition, and to provide a synthetic leather obtained by the method.
This water-based dry laminating adhesive composition for synthetic leather comprises (A) a water-based polyurethane resin, (B) a crosslinking agent and (C) a thickening agent. The softening temperature of the component A is ≤80°C and the melt viscosity at 80°C of the component A is ≤105 Pa.s, and the softening temperature of the resin cured product formed by reaction between the components A and B is ≥120°C. The other objective synthetic resin is produced by the following process: the water-based dry laminating composition is applied onto a surface skin layer formed in advance on a release paper and then dried to form an adhesive layer, which is then dry-laminated with a fibrous base material.
