Solventless adhesive compositions and laminate materials prepared therefrom

A solventless adhesive composition, comprising:

• (A) an isocyanate component comprising a prepolymer which is the reaction product of reactants comprising:
• (a) at least one monomeric cycloaliphatic isocyanate compound comprising at least one cyclohexyl(ene) group and more than one isocyanate groups, and (b) at least one first polyol selected from the group consisting of a first polyester polyol, a first polycarbonate polyol, a first polyether polyol, and combinations thereof, wherein the prepolymer comprises more than one free isocyanate groups;
• wherein the first polyol comprises from 10 to 50 wt % of the first polycarbonate polyol, from 40 to 85 wt % of the first polyester polyol, and from 0 to 20 wt % of the first polyether polyol, based on the total weight of the first polyol,
• (B) a polyol component comprising at least one second polyol selected from the group consisting of a second polycarbonate polyol, a second polyester polyol, a second polyether polyol, a mixture of the second polycarbonate polyol, the second polyester polyol and the second polyether polyol, and any combinations thereof.
