Abstract

A liquid photocurable resin composition having excellent applicability in a high speed drawing condition and high curability, providing a stable coating film which generates little hydrogen gas when used as a coating material for optical fiber. The liquid photocurable resin composition comprises 10-80 wt % of a polymer having an ether bond or an ester bond, and an ethylenically unsaturated group; 5-50 wt % of at least one monomer according to the formula ##STR1## wherein R.sup.9 is a hydrogen atom or a methyl group, R.sup.10 is an alkylene group having 2-4 carbon atoms, and n denotes an integer from 1-10; 0.1-10% by weight of a photopolymerization initiator; and optionally other compounds comprising one or more ethylenically unsaturated groups.
