PURPOSE:To improve wetting, lengthen the tack retention time, and improve the long-term adhesion, etc., by incorporating a phenol or cresol derivative plasticizer having terminal reactive hydroxyl groups into a solvent type polyurethane resin adhesive. CONSTITUTION:A principal component is prepared by dissolving 100pts.wt. thermoplastic polyester urethane rubber, 5-30pts.wt. phenol or cresol derivative plasticizer having terminal reactive hydroxyl groups (e.g., phenoxyethanol), and 5-50pts.wt. phenolic resin in an organic solvent. This principal component is combined with a curing agent component comprising a polyisocyanate or an isocyanato-terminated urethane prepolymer (e.g., triphenylmethane triisocyanate) to give an objective polyurethane resin adhesive. This adhesive is suitably used in the dry laminating of a surface material on a base material with the adhesive applied on one side of each material.
