摘要：
A polyurethane based adhesive containing one polyol compound derived from caprolactone monomer having a number average molecular weight between 200 and 1000 combined with a polyisocyanate compound. The functionality of the polycaprolactone polyol is between 1 and 4. Other aspects include a polarizing layered structure, a polarized lens and a method for manufacturing same all of which include the polyurethane based adhesive. The adhesive avoids delamination and is useful in optical applications where it will be in contact with water, for example during surfacing or edging process.
