Abstract: Translucent multiphase adhesive comprising at least one continuous phase and dispersed domains, the at least one continuous phase having a refractive index of more than 1.45 and a permeation rate for water vapour of less than 100 g/m
2 , and the disperse domains being present in a size range of 0.1 μm to 50 μm and being included in a weight fraction of not more than 10 wt% in the adhesive, characterized in that the disperse domains are polymeric in nature and have a water vapour permeation rate of less than 100 g/m
2 d and a refractive index of less than 1.45.
