Abstract: 1. Process for the preparation of aqueous paraffin dispersion by dispersing paraffin in water in the presence of dispersants based on cationic polyelectrolytes, wherein a mixture composed of A. a copolymer, in the form of its mineral acid salt, which contains from 60 to 80 parts by weight of (meth)acrylamide, from 15 to 35 parts by weight of a di-C1 -C3 -alkylamino-C2 -C4 -alkyl ester of (meth)acrylic acid and from 1 to 10 part by weight of (meth)acrylic acid as monomer units and B. a water-soluble anionic surface-active agent, in the form of its alkali or ammonium salt, which contains sulfo groups or more than one carboxyl group, the weight ratio A : B being from 20:1 to 3:1, is employed as the dispersant.

Abstract: Mixt. of 0.5-10 pts. wt. trimethylamine per 100 pts. wt. of another tert. amine is used as the tert. amine in fatty alkyl diketene, (I), prepn. by (a) reacting fatty acid halides with tert. amines in inert, organic solvents at up to 90 deg.C; (b) washing out the reaction mixt. with water; (c) separating the organic phase; and (d) recovering (I) by organic solvent evaporation. Aq. emulsions of (I), or mixts. of (I), are used as bulk sizing agents for paper, e.g. in 0.05-0.15% concn., calculated as solids, w.r.t. pulp. Trimethylamine addn. suppresses viscosity increase during amine addn. and increases purity of (I).

Abstract: A print paste for printing textiles of polyester, cellulose acetate, cellulose triacetate and mixtures of the same with other fibers which is based on a disperse dye, thickener, ethanolamide of a carboxylic acid and water and which is characterized by a content of at least one phenol which has been oxyethylated twice to six times. The paste yields prints having excellent color strength and levelness.
