Abstract: A process for the low solvent or solvent free coating of heat resistant substrates by using a coating substance which has a melting point or range below about 200.degree. C and which is heat crosslinkable. The substrate is coated at temperatures between about 20.degree. and 250.degree. C and the coating is subsequently heated to more elevated temperatures to effect crosslinking. The coating substance contains active hydrogen, preferably hydroxyl bearing compounds and blocked polyisocyanates which become reactive when the coating substance is heated to effect cross-linking. In a preferred embodiment, the blocked polyisocyanates consist of at least 40 equivalent percent alkanol or cycloalkanol blocked polyisocyanates. Also a coating substance containing at least 50 wt.% of a combination of active hydrogen, preferably hydroxyl bearing compounds and blocked isocyanates. The combination has a melting point of less than 200.degree. C and a blocked isocyanate group to active hydrogen ratio of about 1:2 to 1:9.

Abstract: Pigment preparations containing 3 to 80 percent by weight of an organic or inorganic pigment, 0.5 to 85 percent by weight of a resin containing carbodiimide groups and 0 to 75 percent of an organic solvent free from amino groups are used for pigmenting synthetic high-molecular materials, especially one-component and two-component polyurethane textile coating compositions.

Abstract: This invention relates to the production of basic modified polyamides produced by the polycondensation of lactams or .omega.-aminocarboxylic acids with 0.1 to 5 mol of triamines of the formulaH.sub.2 N -- (CH.sub.2).sub.n -- NH -- (CH.sub.2).sub.n -- NH.sub.2where n equals 2 to 6 per 100 mol of lactam and 2 equivalents of carboxyl groups in the form of dicarboxylic acids and monocarboxylic acids per mol of triamine, using a molar ratio of monocarboxylic acids to dicarboxylic acids of between 10 : 1 and 1 : 20, which polyamides are dyed with reactive dyes.
