HIGH REFRACTIVE INDEX AQUEOUS POLYURETHANE DISPERSION COATING COMPOSITIONS

摘要

High refractive index aqueous polyurethane dispersion primer coating compositions that provide transparent, impact-resistant, and adhesive primer coatings when applied and cured on a substrate, are provided herein. These polyurethane coating compositions coating compositions comprise a polyurethane polymer having aromatic functional groups in an amount ranging from about 16% to about 42% by weight of the solids of the polyurethane polymer and provide primer coatings having a refractive index ranging from about 1.53 to about 1.63. Processes for making such high refractive index coating compositions; processes for coating substrates with such high refractive index coating compositions; and articles coated with such high refractive index coating compositions are also provided herein.
