    摘要： The present invention relates to a process for the production of powder coating compositions having a glass transition temperature of 20.degree. to 80.degree. C. bya) homogeneously dissolving in an inert solvent or solvent mixture having a boiling point or range between 50.degree. and 150.degree. C.A) a polyol component having a hydroxyl value of 30 to 155 and a glass transition temperature of 30.degree. to 120.degree. C. and containing at least one hydroxy-functional copolymer of olefinically unsaturated monomers,B) a polyisocyanate component containing blocked isocyanate groups, having a glass transition temperature of -45.degree. to +45.degree. C. and containing at least one ketoxime-blocked polyisocyanate andC) a catalyst component containing at least one catalyst for the reaction between blocked isocyanate groups and hydroxyl groups components, wherein components A) and B) are present in an amount which is sufficient to provide an equivalent ratio of blocked isocyanate groups to hydroxyl groups of 0.5:1 to 1.5:1,b) freeing the resulting solution from the solvent andc) simultaneously and/or subsequently converting the solid obtained into powder form.The present invention also relates to the powder coating compositions obtained by this process and their use for the production of coatings of heat-resistant substrates.
