ABSTRACT:
The invention concerns a photocurable adhesive composition comprising, based on total weight of photopolymerizable monomers and/or oligomers of the composition:(A1) 20 to 80 wt % of at least one diacrylate monomer or oligomer thereof (A1);(A2) 80 to 20 wt % of at least one dimethacrylate monomer or oligomer thereof;(B) 0 to 50 wt %, of at least one copolymerizable monomer different from components (A1) and (A2);with the proviso that the composition is free from any thio(meth)acrylate (—SCOCR′═CH2, with R′═H or CH3) monomer or oligomer thereof.
