Abstract:
The present invention relates to novel dyestuffs of formula (I) wherein the substituents have the meanings defined in the claims, the production of such dyestuffs, the use of these dyestuffs and material dyed or printed by such dyestuffs.
Abstract:
The present invention relates to disperse azo dyes based on a phthalimido-substituted aniline coupling component and an aromatic-carbocyclic or an aromatic-heterocyclic diazo component, to a process for the preparation of such dyes and to their use in the dyeing or printing of semi-synthetic and, especially, synthetic hydrophobic fibre materials, more especially textile materials.
Abstract:
Disclosed are novel colorant compounds which contain one or more ethylenically-unsaturated (vinyl), photopolymerizable radicals which may be copolymerized (or cured) with ethylenically-unsaturated monomers to produce colored compositions such as colored acrylic coatings and polymers, e.g., coatings and polymers produced from acrylate and methacrylate esters, colored polystyrenes, and similar colored polymeric materials derived from other ethylenically-unsaturated monomers. The present invention also pertains to processes for the preparation of certain of the photopolymerizable colorant compounds.
Abstract:
