Abstract: Coating compositions are described including silica nanoparticles functionalized with an alkenyl silane, a dispersing agent, and a compound including a polyethylene oxide segment containing at least one hydroxyl group, at least one silane, and optionally a hydrophobic group. The coating compositions further include at least two multifunctional (meth) acrylate monomers. Also described are articles including the dried and cured coating composition disposed on a substrate. The articles exhibit anti-fog characteristics and often also mechanical durability.

Abstract: Articles are described comprising a substrate and a hardcoat layer disposed on the substrate. The hardcoat layer comprises the hydrolyzed and condensed reaction product of a composition comprising: i) first hydrophobic silane monomer(s) having the formula R1Si(OR)3 wherein R and R1 is methyl or ethyl; ii) optional second silane monomer(s) having the formula (R2)4-mSi(OR)m or Si(OR)4, wherein R, R1 and R2 are organic groups with the proviso that R1 is not methyl or ethyl and m ranges from 1 to 3. The hardcoat layer N may further comprises 10 to 30 wt. % silica nanoparticles. A surface layer comprising a hydrophilic silane may be disposed on the hardcoat layer. Also described is a method of using an article having a rewritable surface, hardcoat coating compositions, and methods of making hardcoat compositions and articles.
