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.
