Abstract: The invention relates to a color-pigmented high molecular weight organic material structured from a radiation-sensitive precursor by irradiation, the pigmentation of which material consists of extremely fine particles, at least 80 mol % of the pigmentation consisting of a pigment of the class diketopyrrolopyrrole, dioxazine, isoindoline, isoindolinone, disazo condensation yellow or benzimidazolonazo, each containing at least one --NHCO-- group, and, where appropriate, a second pigment of the class diketopyrrolopyrrole, dioxazine, isoindoline, isoindolinone, benzimidazolonazo, disazo or phthalocyanine, and, when the structure of the main pigment is point-symmetrical, the two pigments being present in a balanced molar ratio of from 1:1 to 7:3. Those materials are used preferably in the form of thin layers which are built up in patterns in one or more layers on a transparent substrate and can be used, for example, as optical color filters.

Abstract: A radiation sensitive composition comprising (a) a terpolymer containing 20 to 70 mole percent of an acid-labile repeating unit, 3 to 40 mole percent of an acrylic or acrylonitrile based repeating unit and a repeating unit containing silicon side-chains and (b) a photo-acid generator. The silicon content of terpolymer is 7 to 20 weight percent. The composition is used primarily in the formulation of multilayer positive operating photoresists.

Abstract: A terpolymer containing 20 to 70 mole percent of an acid labile repeating unit, 3 to 40 mole percent of an acrylonitrile based repeating unit and a repeating unit containing silicon side chains. The silicon side chain repeating unit is provided in sufficient amounts so that the terpolymer silicon content is 7 to 20 weight percent. The terpolymer is used primarily in the formulation of multilayer positive operating photoresists.

Abstract: This invention relates to a black-pigmented high molecular weight organic material which is structured from a radiation-sensitive precursor by irradiation, the pigmentation of which material consists of coloured organic pigments, at least one of which is in latent form before irradiation. This material is preferably used as a thin layer which is built up in the form of patterns on a transparent substrate and which can be used, for example, as black matrix for optical colour filters. This invention also relates to a process for the preparation of this material as well as to novel soluble derivatives of yellow disazo condensation pigments which can be used in this process.
