ABSTRACT:
The invention provides a radiation-curable liquid resin for use as a secondary coating of lightwave guides which is a reaction product of (meth)acrylic acid or -acid chloride or isocyanatoalkyl-(meth)acrylate with a 1:2 addition compound of a diepoxide with a mean molecular weight.ltoreq.1000 and a short-chain .alpha.,.omega. -diol with a mean molecular weight.ltoreq.700 or with a 1:2 addition compound of a diepoxide with a mean molecular weight.ltoreq.400 and a monovalent aliphatic alcohol with a mean molecular weight.ltoreq.200, where the diepoxide is an aliphatic-aromatic or aromatic diglycidylether, an aliphatic or cycloaliphatic diepoxide or a silicon-organodiepoxide, and where the short-chain .alpha.,.omega. -diol is an .alpha..omega. -hydroxy-terminated polyoxyalkylene, an .alpha.,.omega. -hydroxy-terminated polyester, an .alpha.,.omega. -hydroxy-terminated polybutadiene, an .alpha.,.omega. -hydroxyterminated organo-functional polysiloxane or an .alpha.,.omega. -alkanediol with a mean molecular weight.ltoreq.200.
