1. Claims for the contracting states : BE CH DE FR GB IT LI NL SE Curable synthetic resin compositions comprising A) a polyetherurethane urea amine with = 2 reactive amino-hydrogen atoms per molecule, prepared by the reaction in a first stage of 1a Polyalkylene-polyether-polyols with a mean molecular weight between 500-10000 and an excess of a 1b di-or poly-functional aromatic iso-cyanate. in which the ratio of NCO-groups to OH-groups is between 1.5 and 2.5. and the resulting masked compound with 1c Phenols (POH) in which the POH/NCO ratio is between 0.5 and 1.5, and further conversion of the resulting carbamic acid aryl esters in a second stage with 2 an excess of at least one di- and/or poly-functional amine compound which contains at least two reactive amino-hydrogen atoms per molecule in the ratio of amino groups : masked NCO-groups of 1.5 - 2.5 B) Glycidyl compounds with an average of more than one epoxide group per molecule and optionally C) usual fillers, pigments, accelerators, viscosity regulators and additives. 1.
