Crosslinkable compositions having low viscosity for coatings and materials with high refractive index and high thermal deflection temperature

摘要

Disclosed is a crosslinkable composition, which comprises a component a) at least one diglycidyl tetra (meth) acrylate bisphenol fluorene ether a component b) at least one diluent from mono (meth) acrylates of a monoalcohol comprising a structure biphenyl, cumyl or benzyl and at least one optional component from components c), d) and e). It also relates to its use for coatings or materials, in particular for 3D printed articles for optical applications, as it also relates to the crosslinked composition and the finished product, in particular the resulting 3D article.
