The adhesive bonding of matted PMMA with customary polymerization adhesives leads to very shiny bond seams, since the cured polymerization adhesives have a shiny surface. This emphasizes the very joining zones which it is intended that the viewer of bonded products should not perceive. The adhesive should therefore be matted after curing. The adhesive has for its basis a polymerization adhesive, preferably a (meth)acrylate-based adhesive. Two different kinds of silica are added as disperse powder to the polymerization adhesive, namely a silica powder having an average particle size of from 1 &#x3bc;m to 10 &#x3bc;m (matting agent) and a silica powder having an average particle size of more than 10 &#x3bc;m up to 200 &#x3bc;m (texturing agent).
