Abstract
A solvent based adhesive composition comprising at least one isocyanate component comprising an aromatic-based isocyanate wherein the weight of the free monomeric isocyanate is less than 1 wt. % based on the weight of the isocyanate component, and at least one isocyanate reactive component comprising at least one phosphaste ester polyol is disclosed. A procedure for making the adhesive as well as a laminate partially made from the adhesive and a procedure for making the laminate are also disclosed.
