The dyestuffs of the formula ##STR1## in which D is the radical of a diazo component,SO.sub.2 X is the radical of a fibre-reactive group,and the remaining substituents have the meaning given in the descriptionare suitable for dyeing and printing hydroxyl- and amido-containing materials.
摘要:
The yield and purity of the condensate obtained in the reaction of cyanuric fluoride with an aqueous amine solution is improved by introducing the reactants into a reactor (1) at a differential rate which results in intensive mixing and substantially completing the reaction in the reactor (1) with no back-mixing, the reactor (1) preferably being a tube (1) into which one nozzle (2) opens axially and one or more nozzle(s) (4) open(s) concentrically thereto.

摘要:
Transparent copolyamides with very good processibility, very good mechanical properties, excellent transparency and hydrolysis stability in boiling water, and alloyability with other polyamides, are obtained through polycondensation of alkyl derivatives of dicycane and additional polyamide-forming components, together with isophthalic acid and an .omega.-aminocarboxylic acid or its lactam with more than 8 C-atoms, or salts thereof, or a stoichiometric mixture of an aliphatic dicarboxylic acid and an aliphatic diamine.The copolyamides of the invention are excellently suitable for the production of molded articles, thanks to their low processing viscosity.
摘要:
A heat-curable, epoxy-free coating composition comprises a dry blend of at least two different binder resins, each binder resin comprising of (a) a carboxyl-terminated polyester resin having an acid value from 20 to 200 mg KOH/g and a glass transition temperature of at least 40.degree. C., and (b) a .beta.-hydroxylalkylamide with at least two .beta.-hydroxylalkylamide groups per molecule; the at least two different binder resins differing in functionality, or in other words in the number of carboxyl and/or .beta.-hydroxylalkylamide groups per binder resin molecule. Along with the binder resins, the coating composition optionally includes further additives that are typical for the processing and use of powder coatings.
摘要:
Reactive dyestuffs which, in the form of the free acid, correspond to the following formula ##STR1## wherein D is the radical of an organic dyestuff of the mono-azo, polyazo or metal complex azo series and the other substituents have the meaning given in the description, show improved application properties.
