Abstract: A process for coloring paper with an acid dye and/or direct dye in an aqueous medium in the presence of a water-soluble reaction product of an alkylating agent, possessing an aromatic substituent, with a cationic polyelectrolyte. The process gives papers with high color strength and substantially avoids cylinder twosidedness of the coloration.

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: Water-soluble benzylated polyamidoamines which contain from 0.1 to 0.9 mole of benzyl groups per equivalent of nitrogen, and onto which from 20 to 400 parts by weight of ethyleneimine or propyleneimine have been grafted per 100 parts by weight of polyamidoamine, processes for the preparation of the materials, and the use of the materials as cationic assistants in processes for coloring paper with acid dyes and/or direct dyes in an aqueous medium. The papers obtained show a high color strength, with substantially no two sidedness of the coloration.

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: Prepn. of a low-melting foam suppressor in fine particulate form comprises spraying the foam suppressor melt onto fine particles of inert, inorganic support material 0.2-4 pts. wt. of foam suppressor melt and one pt. wt. of carrier material having a mean particle dia. less than 100 micron are used; the carrier particles are at a higher temp. than the m.pt. of the foam suppressor and spraying is carried out until the mixt. agglomerates to particles of dia. 100-1500 micron; there after 0.02-0.3 pts. fine particles having a softening point above the temp. of the mixt. are added and the mixt. is allowed to cool to below the melting temp. of the suppressor. Used as a foam suppressor for household washing powders where the basic anionic constituents tend to excessive foam prodn. Method enables a low-melting foam suppressor to be produced in a powdered form which has a long shelf life. The later addn. of the quantity of powder, which may be the same material as the original carrier material, results in stabilisation of the agglomerated material.
