Abstract
Abstract Compounds of formula I ##STR1## wherein R 1 is hydroxyl or glycidyloxy, R 2 is hydrogen, alkyl, alkoxy, halogen, aryl, aralkyl or alkaryl, R 3 is hydrogen or alkyl or both R 3 s together are alkylene, and q is 1 to 3.5, together with epoxy resins and thermoactivatable hardeners and/or curing catalysts, are suitable for the preparation of curable mixtures. The cured products obtained therefrom can be employed for the preparation of electrically conductive coatings or patterns by tempering at elevated temperature or by irradiation with actinic light. Metal can be deposited without current on said electrically conductive coatings or patterns.
