Abstract
Abstract PHOTOPOLYMERIZABLE ELEMENTS HAVING IMPROVED ADHERENCE TO A SUBSTRATE, E.G., A METAL, GLASS OR ORGANIC POLYMER FILM OF A LAYER OF AN ETHENICALLY UNSATURATED PHOTOPOLYMERIZABLE MONOMER AND A MARCOMOLECULAR ORGANIC POLYMER BINDER, PREFERABLY A POLYACRYLATE OR METHACRYLATE CONTAINING A SMALL AMOUNT OF AN ORGANOSILINE. THE ORGANOSILANE MAY BE AN ALKYL, VINYUL, OR ARYL, TRALDOXY, TRICHLORO, OR TRIHYDROXY SILANE OR A CONDENSED, POLYMERIC SILANE. THE ORGANOSILANE CAN BE ADMIXED WITH THE PHOTOPOLYMERIZABLE COMPOSITION JUST PRIOR TO COATING IT ONTO THE SUBSTRATE. THE ELEMENTS CAN BE USED TO MAKE PRINTED CIRCUIT BOARDS.
