Patent ID: 8048522

Claim:
A pressure-sensitive adhesive material or a sealing material which has a three-dimensional structure and a defined cross-sectional contour, wherein said material is present in a form of strings, strands or strips, wherein said strings, strands or strips have a round, semicircular, oval, elliptical, triangular, quadrangular, V-shaped, polygonal or irregular cross-sectional contour and a surface that is bent, curved or provided with edges corresponding to said cross-sectional contour, and wherein said material consists of a polymerizable mass produced by polymerization and said polymerizable mass consists of at least one compound selected from the group consisting of aromatic (meth) acrylates, alicyclic (meth)acrylates, polycyclic (meth) acrylates, heterocyclic (meth) acrylates, and epoxide acrylates, along with at least one compound selected from the group consisting of acrylic acid and methacrylic acid or at least one compound selected from the group consisting of vinyl ethers, vinyl esters, and styrene, and a radiation sensitive initiator in an amount ranging from 0.5 to 5% wt. of the polymerizable mass, wherein said radiation sensitive initiator is selected from the group consisting of 2-hydroxy-2-methyl-1-phenyl-1-propanone, 1-hydroxy-cyclohexyl-phenyl-ketone, iodonium, (4-methylphenyl) [4-(2-methylpropyl)-phenyl]hexafluorophosphate(1-), 2-benzyl-2-(dimethylamino)-1-[4-(4-morpholinyl)phenyl]-1-butanone, a mixture of 50%-wt of 1-hydroxy-cyclohexyl -phenyl-ketone and 50%-wt of benzophenone, bis [2,6-difluoro-3-(1H-pyrrol-1-yl)phenyl]titanium, phosphine oxide phenyl-bis-(2,4,6-trimethyl benzoyl and 2-hydroxy-1-[4-2(hydroxyethoxy)phenyl]-2- methyl-1-propanone.
