Patent ID: 7807740

Claim:
A two-component reaction resin with a resin component (A), which contains, as curable component (a), at least one free radical-curable, ethylenically unsaturated compound, an agent (b) for adjusting the reactivity and the gel time and at least one comonomer (c), and a hardener component (B), which is disposed separated therefrom to inhibit reaction and is a curing agent for the resin of the resin component (A), which is characterized in that the resin component (A), as agent (b) for adjusting the reactivity and the gel time, contains a pyrocatechol derivative of the general Formula (I): in which R represents a hydrogen atom, a methyl, ethyl, n-propyl, iso-propyl, n-butyl or iso-butyl group, which optionally is substituted by a hydroxy, alkoxy or alkylamino group, a group of the formula R 1 OOC—, R 1 O—, R 1 NH—, or R 1 R 2 N—, in which R 1 and R 2 independently of one another represent hydroxy-substituted alkyl groups with 1 to 4 carbon atoms, an aldehyde group, a polyalkylene oxide group of Formula (II): in which m is a whole number with a value from 1 to 3, n is a whole number with a value from 1 to 50, R 3 is a hydrogen atom or a methyl group and R 4 is a hydrogen atom, an alkyl group with 1 to 4 carbon atoms or a group of Formula (III)
