    Abstract: 1489656 Paper-treating aminoplast resins BASF AG 24 Jan 1975 [25 Jan 1974] 3118/75 Heading C3R [Also in Divisions D1-D2] A condensation product is prepared in a single step reaction by mixing together (a) a neutralization product of pH 6-8 obtained from at least one carboxylic acid of pK 2 value at least 3À5 and ammonia and/or at least one C 1-5 primary alkyl amine, (b) 0À8-1À4 mols per carboxyl group in (a) of urea or an equivalent amount of another carbonamide, (c) 0À8-1À4 mols per carboxyl group in (a) of dicyandiamide, and (d) 3À2-4À5 moles of formaldehyde per mole of dicyandiaamide, and, after the reaction mixture has reached its highest temperature (due to the spontaneous reaction) and a constant pH, heating it at 70-100‹ C. for 0À5-5 hours. Suitable acids for (a) are C 1-5 alkane monocarboxylic acids; suitable amides (b) are formamide, acetamide, urea, alkyl- and dialkylureas, and urethanes. In Examples 1-4 a solution of 1 mole of urea and 0À75-1À25 moles of ammonia is brought to pH 7 with formic acid, then 1 mole of dicyandiamide and 3À5-4À2 moles of formalin are added; the pH becomes 5 and the mixture is heated for 0À15-5 hours, then neutralized with NaOH. In Example 5 2 moles of formamide or acetamide are used instead of the urea in a similar process. The products may be used as solutions or be spray dried. Uses.-Dye fixing agents and sizes for paper.

    Abstract: Concentrated solutions of basic dyes comprise a salt of a basic dye with a water-soluble carboxylic acid and an anhydrous or water-containing solvent miscible in all proportions with water and selected from polyhydric alcohols and esters and ethers thereof, polyethers, amides, lactones, nitriles, dimethyl sulphoxide, tetrahydrofuran and dioxan. The dye solutions may be used to make non-drying inks by dilution with, e.g. ethylene glycol, for use in self-recording instruments, stamp-pads and typewriter ribbons. The dye solutions may contain excess, e.g. 1.5 to 2 times the stoichiometric equivalent, of water-soluble acid and may also contain water up to 50% by weight of the solvent. The solutions may contain 20-80% by weight of basic dye, the preferred dyes being from the diarylmethane, triarylmethane and diazapolymethine series. Specified acids are fromic, acetic, propionic, maleic and lactic acids. Numerous solvents are specified the preferred ones being ethylene glycol, diethylene glycol monoethyl ether, propylene glycol, dipropylene glycol, formamide and dimethylformamide. The preferred method of preparing the dye solutions comprises dissolving the carbinol base of the basic dye, which may still be water-wet, in a mixture of water-soluble acid and said solvent. Specifications 808,308 and 865,965 are referred to.ALSO:Concentrated solutions of basic dyes comprise a salt of a basic dye with a water-soluble carboxylic acid and an anhydrous or water-containing solvent miscible in all proportions with water and selected from polyhydric alcohols and esters and ethers thereof, polyethers, amides, lactones, nitriles, dimethyl sulphoxide, tetrahydrofuran and dioxan.
