Abstract
The invention relates to a crosslinkable composition, which comprises a component a) at least one halogenated bisphenol A diglycidyl ether tetra(meth)acrylate and a component b) at least one diluent from mono(meth)acrylates of a monoalcohol comprising a biphenyl structure, and at least one optional component from components c), d), e), f) and g). 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 to the finished product, in particular the 3D article which results therefrom.
