摘要:
Pigment preparations which contain an organic pigment and/or carbon black and a surfactant from the sulphosuccinic acid ester and/or alkylbenzenesulphonate series and which have been dried, if appropriate after wet comminution, by spray- or freeze-drying from an aqueous medium, and the use of these preparations for pigmenting high molecular weight organic material, in particular thermoplastics.
摘要:
New polyisocyanate-polyaddition compounds, a process for their preparation and their use as wetting or dispersing agents for the incorporation of solids, in particular pigments, in lacquer or synthetic resin formulation.
摘要:
The invention relates to insecticidal and acaricidal agents which contain water-insoluble active compounds and water-soluble oxyalkylation products of compounds prepared by adding styrenes onto phenols or naphthols, and which form a colloidal solution when diluted with water, and to their use.
摘要:
The lyotropic, liquid-crystalline, aqueous phase of a reactive dyestuff of the formula ##STR1## wherein M.sym. represents H.sym. or an alkali metal cation (preferably Na.sym., K.sym. or Li.sym.) andR is a fibre-reactive groupingpresent in water at room temperature in a concentration of 10-25%, if appropriate in the presence of concentration-increasing additives and/or buffer substances, is highly suitable for preparing dyebaths and print pastes for application to natural and synthetic substrates, in particular cotton, wool, regenerated cellulose, paper and leather.
摘要:
Process for the preparation of low-salt liquid dyestuff preparations, characterized in that they are obtained by:a) diazotization of an aromatic amine,b) 2-fold coupling of the diazo component obtained according to a) to I-acid-urea, in the presence of an inorganic base and in the absence of an organic base,c) desalination and, if appropriate, concentration by means of a pressure permeation of the reaction mixture obtained according to b), so that an inorganic salt content of less than 1% by weight is achieved.
摘要:
Liquid finished formulations which are stable to storage and hydrolysis and are based on the lyotropic liquid crystal aqueous phase of the dyestuff of the formula ##STR1## which is present in water in a concentration of 23-35% at room temperature, are outstandingly suitable for the preparation of dyebaths and printing pastes for dyeing cotton, wool, regenerated cellulose, paper and leather.
