    Abstract: The present invention is drawn to hot-melt adhesives for bonding vitreous plastic materials to thermoplastic or thermosetting plastic materials, and to the use of these adhesives for making vehicle lamps or headlamps comprising lenses, especially bearing a scratch-proofing coating, made of a vitreous plastic material, and lamp bodies made of a thermoplastic or thermosetting plastic material, where the lenses and lamp bodies are bonded together with these hot-melt adhesives. The hot-melt adhesives of this invention are characterized in that they contain: a) from 0.5 to 15% by weight of optionally grafted thermoplastic elastomers; b) from 5 to 40% by weight of optionally grafted poly-&agr;-olefins except polyisobutylene; c) from 5 to 45% by weight of adhesive resins; and d) from 5 to 55% by weight of polyisobutylenes.
