摘要:
This invention relates to DVDs made from polycarbonate and a special UV curable bonder material consisting of A) an urethane acrylate oligomer as binder, which is the reaction product of i) one or more polyisocyanates and ii) one or more hydroxyfunctional lactone ester (meth)acrylates having a number average molecular weight of from 200 g/mol to 2000 g/mol and having the formula: CH2═C(R1)—C(O)—O—R2—[O—C(O)—R3]n—OH wherein, n is an integer from 1 to 5, R1 is hydrogen or methyl, R2 represents an alkylene group or substituted alkylene group having from 2 to 10 carbon atoms and R3 represents a straight or branched chain alkylene group of from 3 to 8 carbon atoms, and which may be substituted with one or more alkyl groups having from 1 to 12 carbon atoms, B) a reactive thinner, comprising of mono functional acrylates and/or (meth)acrylates C) a photo initiator and D) optional additives which offers improved performance at high data transfer rates.
