Reactive resin for marking roads, which is constituted on the basis of (meth) acrylates, the reactive resin being characterized by having the following constituent materials: from 20% by weight to 30% by weight of crosslinking agents in which cases it is an allyl (meth) acrylate or a di- and / or a tri (meth) acrylate, from 30% by weight to 40% by weight of some (meth) acrylates and / or monomers copolymerizable with (meth) ) acrylates, which are selected from alkyl (meth) acrylates of straight chain, branched or cycloaliphatic alcohols, with 1 to 40 C atoms, mono- or dicarboxylic acids unsaturated in α, β, esters of acrylic acid or methacrylic acid with divalent alcohols, acrylamide, methacrylamide, (meth) acrylate of 1-dimethylaminoethyl, 1-alkenes or styrenes, from 10% by weight to 20% by weight of urethane (meth) acrylates), from 15% by weight to 25% by weight of prepolymers, which are selected from poly (meth) acrylates or polyesters, of 0% by weight to 5% by weight of accelerating agents.
