Abstract:
Articles such as optical displays and protective films, comprising a (e.g. light transmissive) substrate having a surface layer comprising the reaction product of a mixture comprising a hydrocarbon-based hardcoat composition and at least one perfluoropolyether urethane additive. The surface layer exhibits low lint attraction in combination with high contact angles. Hardcoat coating compositions comprising a perfluoropolyether urethane additive and a silicone (meth)acrylate additive are also described.
