Abstract:
Compounds of formulaA(B).sub.x, (I),wherein x is an integer from 1 to 4,A is the radical of a chromophore of the quinacridone, anthraquinone, perylene, indigo, quinophthalone, isoindolinone, isoindoline, dioxazine, phthalocyanine or azo series, which radical contains x N-atoms attached to B, preferably with at least one directly adjacent or conjugated carbonyl group,B is a group of formula ##STR1## and, if x is 2, 3 or 4, may also be one, two or three hydrogen atoms. The symbols Q, R.sub.1, R.sub.2, R.sub.3, R.sub.4, X, Y, Z, m and n, are as defined in claim 1.These carbamate group-containing soluble chromophores are distinguished by outstanding solid state fluorescence in the UV range as well as the by ease with which they can be converted to the corresponding pigments in the substrate in which they are incorporated.
Abstract:
Compositions for making structured color images comprising (a) a soluble pigment precursor which can be transformed to an insoluble pigment by means of chemical, thermal, photolytic or radiation-induced method, and (b) a binder polymer or prepolymer, or a positive or negative resist-type resin which can be structured by crosslinking, polymerization or depolymerization by applying heat or electromagnetic irradiation. The compositions can be applied to optical and thermal recording, printing, and the production of color filters for Liquid Crystal Displays, with high accuracy, high transparency and high stability.

Abstract:
A method of producing a desubstituted compound, including: applying an external stimulation to a compound A-(B)m having a solvent-soluble group B (wherein A represents a residue of a solvent-insoluble compound, B represents a specific solvent-soluble group, and m represents a natural number, and the solvent-soluble group B bonds to a carbon atom of the residue A of a solvent-insoluble compound), to cause desubstitution of the solvent-soluble group B, and converting the compound to a solvent-insoluble compound to which a hydrogen atom bonds in place of the solvent-soluble group B; a method of producing an organic semiconductor film, including: forming a film of a π-conjugated compound having a substituent represented by formula (2-I), on a substrate; and causing desubstitution of the substituent from the compound; and an organic semiconductor film and an organic electronic device each obtained by these methods: wherein R11 represents a substituent other than a hydrogen atom.
Abstract:
