| 摘要 |
The invention comprises a process for the preparation of a coating, adhesive , film or sheet. In this process a mixture of a polyisocyanate functional, a polyepoxide functional, a polyanhydride functional or a polyketone functiona l compound or polymer and a compound containing reactive hydrogen, in which th e compound containing reactive hydrogen is dispersed in a material which is no n- reactive towards the compound containing reactive hydrogen, which mixture is not or low reactive at ambient conditions and high reactive under selected conditions, is applied onto a substrate at ambient temperature, followed by reacting the above compounds at elevated temperatures. At ambient temperatur e said compound containing reactive hydrogen is a solid material, a powder, a granule, a flake or grind or a mixture thereof which is preferably ground. T he invention comprises further the coating mixtures to be used in the process a nd the coatings, coated substrates, adhesives, films, sheets, impregnated substrates, synthetic leathers, inmould coatings, coated leathers, coated polyvinylchlorides, coated non-wovens, coated coagulated polyurethane substrates, breathable coated substrates, obtained by applying the process.< /SDOAB>
