Abstract
Composite made of two substrates for use for optical, electronic and/or precision-engineered equipment, comprising a first substrate and a second substrate and, arranged so as to connect the first substrate to the second substrate, an adhesive layer, wherein the adhesive layer comprises an adhesive which has, relative to the mixture, (a) from 60% by weight to 90% by weight of a first polymer component based on polyacrylate and (b) from 10% by weight to 40% by weight of a second polymer component based on elastomers, where the second polymer component is essentially not miscible with the first polymer component, so that the adhesive is present in at least two separate phases in the adhesive layer.
