    摘要: Heat-stable structured layers can be manufactured through the application of radiation-sensitive soluble polymers in the form of a layer or film on a substrate, irradiation of the layer respectively film through negative patterns with actinic light or through the use of a light, electron, laser, or ion beam, removal of the non-irradiated layer respectively film parts and, if necessary, through subsequent tempering, in a cost-effective way in dimension-precise and high-quality form and in a single application process, when the polymers used are photopolymers in the form of addition reaction products of olefinic unsaturated monoisocyates with phenolformaldehyde resins. The layers produced with this method resist even high thermal and mechanical stress in immersion soldering processes and protect circuit surfaces effectively and permanently against moisture and corrosion; they are therefore suitable for use, in particular as solder resist and insulating layers in microelectronics.

    摘要: A cost-efficient method for producing dimensionally precise and high-grade heat-resistent structured layers by applying a single coating of a radiation-sensitive soluble polyether-based photopolymer in the form of a layer or foil on a substrate; irradiating the layer or foil through a negative with actinic light or by guiding a light, electron, laser, or ion beam; removing the nonirradiated layer or foil portions; and subsequent optional annealing, wherein the photopolymer comprises an addition product of an olefin-unsaturated monoisocyanate and a polether having at least one hydroxyl group. The layers provided according to the invention can withstand the thermal and mechanical stresses of dip soldering process, and protect circuit surfaces effectively and durably against moisture and corrosion; they are therefore suitable in particular as solder resist and insulating layers in microconductor technology.

    摘要: Oligomeric and/or polymeric radiation-reactive polyimidazole and polyimidazo pyrrolone precursors which are soluble in organic solvents, can be prepared with high purity, i.e., especially without chloride, in a simple manner if an aromatic and/or heterocyclic tetraamino compound is reacted in the presence of a carbodiimide, with an olefinically unsaturated monocarboxylic acid and a dicarboxylic acid, or with an olefinically unsaturated monocarboxylic acid and an aromatic and/or heterocyclic tetracarboxylic acid dianhydride, or with an olefinically unsaturated tetracarboxylic acid diester, in the form of an addition product of the tetracarboxylic acid dianhydride and an olefinically unsaturated alcohol. The radiation-reactive precursors prepared in this manner are suitable, for instance, for the manufacture of highly heat-resistant relief structures.
