LIGHT CURABLE RESIN COMPOSITION

摘要

The present application relates to a resin composition and in particular to a light-curable resin composition.;It is known to achieve a thixotropic behavior of an adhesive composition by adding an inorganic additive like fumed silica. Adding inorganic additives results in significant particle problems as fumed silica is a solid particle and affects the optical performance of the adhesive composition.;In accordance with the invention a particle free resin composition with a thixotropic behavior is provided. The inventive composition comprises
a) 30 to 90 wt % of a urethane acrylate oligomer with a molecular weight greater than 15000,b) 2 to 40 wt % of a (meth)acrylate monomer having a benzene ring, andc) 0.2 to 10 wt % of a photo initiator.
