| 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 (A) 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. |
