Abstract:
A structured pigmented high molecular weight organic material comprising a single-colored layer which comprises pigment particles of an average particle size of 0.1 .mu.m or less and is obtainable from a radiation-sensitive precursor by irradiation,whereinthe organic material comprises at least 5% by weight pigment particles, based on the pigmented material;at least 80 mol % of the pigment particles consist of two components (a) and (b), wherein(a) is selected from the group consisting of mirror-symmetrical or point-symmetrical diketopyrrolopyrrole, dioxazine, isoindoline, isoindolinone and bisacetylacetamidarylene-group-containing disazo pigments, each containing at least one --NHCO-- group, and(b) is selected from the group consisting of diketopyrrolopyrrole, dioxazine, isoindoline, isoindolinone, benzimidazolonazo and disazo pigments, each containing at least one --NHCO-- group, and phthalocyanine pigments,whereincomponent (b) may be present in no more than an equimolar ratio to component (a),when the molecule of component (a) is mirror-symmetrical, component (b) must be present in a molar ratio to component (a) of from 1:5 to 1:1, andwhen the molecule of component (a) is point-symmetrical, component (b) must be present in a molar ratio to component (a) of from 3:7 to 1:1;and when less than 100 mol % of the pigment particles consist of components (a) and (b), the balance of up to 20 mol % consists of one or more components (c).
