The present invention aims to provide a lining composition which overcomes the problems such as environmental problems (e.g. marine pollution) and VOC problem and which has a good cure rate. We have found that this can be achieved by a composition containing a vinyl ester resin as a prepolymer component and an aliphatic or alicyclic polyfunctional allyl ester compound as a crosslinking agent.
