摘要： A substituted acylaminopolyorganosiloxane (A) is a polyorganosiloxane containing substituted acylamino groups linked to silicon atoms of the polysiloxane skeleton via alkylene bridges or mono- or oligo-[alkylene-amino or alkylene-(substituted acyl)amino]-alkylene bridges. The alkylene contains 2-4 carbon atoms and the substituted acylamino groups are at least in part of formula and for the remaining part are selected from substituted acylamino groups of the formulae in which: X1 signifies hydrogen or the group —SO3−M+, X2 signifies hydrogen or the group —SO3−M+, with the proviso that one of X1 and X2 is —SO3−M+ and the other is hydrogen, R signifies C2-6-alkylene or cyclohexylene, and M+ signifies an alkali metal or ammonium cation. The substituted acylaminopolyorganosiloxane (A) and compositions thereof, in the presence of non-ionic or/and anionic surfactants (B), can be used as fat liquoring agents for fat-liquoring of animal hides, skins or pelts.

摘要： A process for the preparation of a coating, coated substrate, film or sheet, in which process a coating mixture comprising a reactive system of polyisocyanate-functional, a polyketone-functional, a polyepoxide-functional, a polyanhydride-functional and/or a poly carbonate-functional compound or polymer and a dispersion or fine powder of a compound containing a reactive hydrogen, which mixture is not or low reactive at room temperature, is applied onto a substrate, resulting in a substrate coated with the coating mixture, followed by reacting the compounds mentioned above by elevating the temperature, in a substrate coated with the coating mixture, followed by reacting the compounds mentioned above by elevating the temperature, in which the reaction temperature and consequently the reaction rate can be adjusted as desired by the addition of an additive to the coating mixture, or to one of the reactants of the coating mixture, prior to the mixing with the other component. According to the invention optionally a second reactive system is present and both systems are essentially reacted as a sequential two step reaction and between these reaction steps the coating is remoulded. The invention further comprises a product obtained by the process.
