Beschreibung
Zusammenfassung:	UV-curable block copolymer composition comprising: (a) 100 parts by weight of a block copolymer comprising at least one polymer block A derived from a monovinyl aromatic compound and at least one polymer block B derived from a conjugated diene, wherein: the content of monovinyl aromatic compound is in the range of from 5 to 50 % by weight based on the total weight of block copolymer; each block A has an apparent molecular weight in the range of from 1,000 to 50,000; and each block B has an apparent molecular weight in the range of from 10,000 to 250,000; and (b) 0.5-30 parts by weight of at least one photoinitiator, characterized in that the block copolymer is a multi-armed block copolymer and at least one photoinitiator is used containing a carbonyl group which is directly bonded to at least one aromatic ring structure.
