    摘要： A curable composition comprises a) at least one epoxide compound E having at least two epoxide groups; b) at least one amine A having at least two amine hydrogens; and c) at least one acrylic ester U; wherein the epoxide compound E comprises at least one epoxide compound E′, the amine A comprises at least one amine A′, and the acrylic ester U comprises at least one acrylic ester U′ whose Hansen solubility parameters for the dipole forces δp and for the specific interactions δh satisfy the following conditions: √{square root over ((δp(U′)−δp(E′))2+(δh(U′)−δh(E′))2)}≥1.5 and √{square root over ((δp(U′)2−δh(U′)2))}−√{square root over ((δp(A′)2+δh(A′)2))}≥0. A suitable choice of the Hansen solubility parameters of the constituents ensures that the acrylic ester is incorporated covalently into the curing material, preventing subsequent evaporation of the diluent.
