Abstract
Disclosed is a solventless adhesive composition comprising (A) an isocyanate component obtained by the reaction of reactants comprising at least one monomeric cycloaliphatic isocyanate compound and at least one first polyol; and (B) a polyol component comprising particularly selected polyols. The solventless adhesive composition can be used for the production of laminate materials, e.g. laminate backsheet of a photovoltaic device, which well meets the requirements of various compliance regulations and has superior performance properties such as bond strength, aging resistance, yellowing resistance, delamination resistance, and the like. A method for producing said laminate material and the resultant laminate material are also disclosed.
