The invention relates to a urea derivative and a resin composition based on this urea derivative and a polymer with reactive groups. The urea derivative has the following formula: <CHEM> where X = 0 or S, R<1> = H or CH2OR<5>, R<2> = an organic group that is at least m-functional with 3-20 C atoms, and m = 2-20, R<3> = H or R<2> or an alkyl group with 1-6 C atoms or an aryl group with 6-10 C atoms, R<4> = H or CH2OR<5>, R<5> = H or an alkyl group with 1-6 C atoms, n = 2-20 and n is less than or equal to m.
