| 摘要 |
<p>The invention relates to a colour-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 colour filters.</p> |
