Microstructure-bearing articles of high refractive index

   
   

Blends of oligomeric urethane multi(meth)acrylate; optionally at least one other monomer selected from the group consisting of acrylic monomers, styrenic monomers and ethylenically unsaturated nitrogen heterocycles, preferably a polyol multi(meth)acrylate; and nanoparticles of an ethylenically unsaturated, preferably (meth)acrylic-functionalized, titanium or zirconium compound can be cured by ultraviolet radiation in contact with a photoinitiator to produce optical resinous articles having high refractive indices, haze ratings of at most 5% and other properties which may be tailored according to the desired use.

Misturas do multi(meth)acrylate oligomeric do urethane; opcionalmente ao menos outro um monomer selecionado do grupo que consiste em monomers acrílicos, em monomers styrenic e em heterocycles ethylenically unsaturated do nitrogênio, preferivelmente um multi(meth)acrylate do polyol; e nanoparticles de um ethylenically unsaturated, preferivelmente (meth)acrylic-functionalized, titânio ou o composto do zirconium pode ser curado pela radiação ultravioleta no contato com um photoinitiator para produzir os artigos resinous óticos que têm os índices refractive elevados, as avaliações do embaçamento de a maioria 5% e as outras propriedades que podem ser costurados de acordo com o uso desejado.
