Abstract

The present invention relates to composition comprising at least one compound obtained from the reaction of at least one compound (i) having a refractive index nD20 of at least 1.50 comprising at least one isocyanate-reactable functional group —XH, wherein each of X is, independently, O or NR, at least one polyisocyanate (ii), and, optionally, at least one compound (iii) comprising at least one isocyanate-reactable functional group —YH and at least one curable functional group Q, wherein each of Y is, independently, O, NR or S, and its use for making high refractive index coatings and films.
