    Abstract: The present disclosure provides a two-component solvent-less adhesive composition. The two-component solvent-less adhesive composition contains the reaction product of (A) an isocyanate component containing the reaction product of (i) an isocyanate monomer and (ii) a first dimer acid polyester polyol; and (B) a polyol component containing (i) a second dimer acid polyester polyol and (ii) optionally, a polyol selected from a polyether polyol, a polyester polyol, and combinations thereof. The two-component solvent-less adhesive composition contains from 15 wt % to 45 wt % units derived from dimer acid, based on the total weight of the two-component solvent-less adhesive composition.
