Abstract
A use of a polymerizable ultraviolet absorber is disclosed, which is applied to a polyurethane preparation. The polymerizable ultraviolet absorber is obtained by reacting an UV absorber having a reactive hydrogen group with a polyisocyanate having three —NCO groups. In addition, a composition for forming polyurethane comprising the aforementioned polymerizable ultraviolet absorber is also disclosed.
