One-component systems comprising blocked polyurethane prepolymers

The present invention relates to a one-component system comprising a blocked polyurethane prepolymer. The subject of the invention is a one-component system comprising a) at least one polyurethane prepolymer based on at least one diisocyanate and/or polyisocyanate and at least one diol and/or polyol, the at least one diol or polyol being a polyalkylene glycol having a number average molecular weight of 900 to 2150 g/mol, and the at least one polyurethane prepolymer being based on at least one polyurethane prepolymer based on at least one diisocyanate and/or polyisocyanate and at least one diol and/or polyol having a number average molecular weight of 900 to 2150 g/mol. Wherein all unconverted isocyanate groups are blocked with at least one malonate, and b) at least one diamine and/or polyamine; the invention also relates to a method for producing same, to the use thereof and to a method for producing artificial leather and (artificial) leather coatings using same. 本发明涉及包含封闭型聚氨酯预聚物的单组分体系。本发明的主题是单组分体系，其包含a)至少一种
