Abstract: The present invention relates to a method for the preparation of highly heat-resistant relief structures by applying radiation-sensitive soluble polymer precursor stages in the form of a film or a foil to a substrate; irradiating the film or the foil through negative patterns with actinic light or by deflecting a light, electron or ion beam; removing the non-irradiated film or foil portions; and optionally, by subsequent annealing; as well as to the use of the relief structures made in this manner. It is provided for this purpose to use precursor stages of polyimidazoles and polyimidazopyrrolones in the form of addition products of olefinically unsaturated monoepoxides on amino group-containing polycondensation products of aromatic and/or heterocyclic tetraamino compounds with dicarboxylic-acid chlorides or esters, or on amino group-containing polyaddition products of the tetraamino compounds and tetracarboxylic-acid dianhydrides.
