Abstract: The resins are prepd. by (a) alkylating at >=15%, (esp. 20-50%) of the sec. N atoms of the polyamido-amine, and (b) reacting the alkylated product with ethylenically unsatd. 3-5C mono- or dicarboxylic acids or their derivs., vinyl sulphonate, acrolein and/or methacrolein at 30-140 degrees C., (pref. 40-120 degrees C). Pref. this reaction is effected with (meth)acrolein. Used to increase the dry strength of paper, without increasing the wet strength. Effective amts. are 0.2-3% calc. on the solid material, added to the fibre suspensions before paper mfr.

Abstract: Conventionally limed hides are delimed for from one to six hours under conventional deliming conditions in respect of liquor length, temperature and pH of the liquor, by a process in which a cyclic carbonate of a polyhydric aliphatic alcohol of 2 to 6 carbon atoms is employed as the active agent.

Abstract: An auxiliary for the soaking of hides and skins, which consists of a salt of the formula I M+[O3S-S-R]- I where R is an organic radical of 1 to 8 carbon atoms, which may carry one or more functional groups, and M+ is one equivalent of a cation, mixtures thereof with other conventional soaking auxiliaries, and processes for their use. Using the novel auxiliary avoids all toxicity hazards and odor nuisance, as well as avoiding oxidation losses, and achieves good loosening of the hair.

Abstract: Easily water-dispersible pulverulent formulations of disperse dyes are prepared by spray-drying a dye solution which comprises (a) one or more disperse dyes, (b) one or more water-soluble anionic dispersants, (c) from 0 to 20% by weight, based on (a+b+c+d), of other surfactants and (d) from 0 to 20% by weight, based on (a+b+c+d) of agents which serve as protective colloids (the proportion of (c+d) being at most 20% by weight). Suitable solvents (e) are formic acid, formamide, N-methylformamide, butyrolactone, ethylene glycol and propylene glycol, which may in addition contain up to 100% by weight, based on (e), of N,N-dimethylformamide or acetic acid or mixtures of these. The formulations obtained by the above process contain the dye in very fine dispersion.

Abstract: Triaminotriarylmethane colorants are obtainable by first reacting an aluminum or iron trihalide complex of a 4,4',4''-trihalotriphenylmethyl halide with a metanilic acid, a sulfanilic acid or a beta -naphthylaminesulfonic acid and then reacting the product with one or more anilines to replace the halogen atoms located in the 4-positions. The compounds according to the invention are very useful as pigments, for example in printing inks, or for toning carbon black.

Abstract: New triarylmethane dyestuffs (I) with a sulphonated benzene ring are of formula (I). In (I) R has formula (II) or (III) R1, R2, R4, R6 and R7 are H, Me or Et, R3 is H, Me, Et or Ph and R5 is Me, Et, Ph, tolyl, methoxyphenyl or ethoxyphenyl. If R1 and R2 are not H, -NR3R4 is -NH2; if -NR3R4 is NEt2, R is not -Q-NMe-Ph (Q is o-phenylene); and if R1 and R2 are H and R is -Q-NH2 or -Q-NH-Ph, no. -NR3R4 is NH2 or -NHPh. (I) are used in printing inks or for toning C black. They are also useful in carbon paper. They are violet to greenish-blue in colour and insoluble in water. (I) can be prepd. by conventional methods, e.g. condensn. of 4,4'-aminobenzophenone with aniline or alpha-naphthylamine and sulphonation, if necessary.
