Abstract

For production of a composite glass pane from at least one silicate glass pane and at least one layer of a transparent plastics material, the plastics layer is glued to the glass pane by means of an UV-hardening adhesive. A homogeneous solution of photopolymerizable acrylic monomers (component A), a polymer (component B) and a photoinitiator (component C) is used as the adhesive, wherein the component (A) consists of a mixture of at least one .alpha., .beta.-unsaturated carboxylic acid and at least one monofunctional .alpha.,.beta.-unsaturated carboxylic acid ester of an alcohol comprising 2 to 10 C-atoms, possibly comprising also oxygen atoms in the form of ether groups and/or hydroxyl groups, and component (B) consists of a polymer composed entirely or predominantly of vinyl chloride, which polymer is possibly after-chlorinated.
