Abstract

The invention relates to the use of partly silanized compounds based on polyisocyanate as crosslinking agents with heightened refractive index in curable coating compositions, more particularly in clearcoat materials for automotive finishing. The invention likewise relates to a coating composition which comprises these compounds as crosslinking agents, and to the use of the coating composition to produce a coating.
