Abstract: PROBLEM TO BE SOLVED: To obtain a liquid water-based dye preparation excellent in water resistance and light resistance and desirable for the production of writing inks or printing colorants by mixing a dye with carbon black and polyethylene glycol. SOLUTION: This preparation comprises 0.1-15wt.%, based on the weight of the preparation, dye comprising 90-100wt.% dye represented by the formula (Kat is a metallic ion or an ammonium ion), 1-40wt.% carbon black having a particle size of 13-100nm, 0.1-15wt.% polyethylene glycol having an average molecular weight of 300-9,000 and the balance of water. This preparation is diluted with water or a mixture comprising water and a water-miscible organic solvent to obtain an ink. It is diluted with a 1-4C alkanol optionally together with water, and the diluted preparation is optionally mixed with a binder to obtain a colorant for a water-based alcoholic coating material or for printing.

Abstract: Aqueous dye formulations contain 0.1-15 wt.% dye, of which 90-100 wt% is an anionic disazo dye, which is a 4,4'-bis(7-amino-1-hydroxy-3-sulpho-naphthyl-2-azo)-stilbene-2,2'-disu lphonate salt of formula (I), 1-40 wt.% carbon black and 0.1-15 wt.% polyethylene glycol (PEG); in which Kat = the equivalent of a metal or ammonium ion. Also claimed are inks containing the formulation, water and optionally water-miscible organic solvent and aqueous-alcoholic varnish colours or printing inks containing the formulation, water and 1-4 carbon alkanol(s).

Abstract: Described is a process for preparing a dispersion of microcapsules by condensing a partially methylated melamine-formaldehyde resin having a molar ratio of melamine:formaldehyde:methanol of from 1:3.0:2.0 to 1:6.0:4.0 in water in which the essentially water-insoluble material forming the capsule core is present in dispersion in the presence of an alkali metal salt of a homopolymer or copolymer of 2-acrylamido-2-methylpropanesulfonic acid as protective colloid at a pH of from 3 to 6.5 by preforming the microcapsules at a temperature of from 20 to 50° C. and then curing the capsule wall of the preformed microcapsules at >50 to 100° C., which comprises adding from 5 to 100% by weight of melamine, based on the melamine-formaldehyde resin, in the course of curing. The microcapsule dispersions are formaldehyde-reduced and of low viscosity.
