A process for the preparation of a heat curable paint binder composition

摘要

The invention relates to a process for the preparation of a heat curable paint binder composition containing a compound comprising hydroxyl amide groups. In a first step a compound comprising hydroxyalkyl amide units and carboxylic acid units is obtained by reacting a cyclic anhydride and an alkanolamine in a mixing device and in a second step the binder composition is obtained by mixing the compound and a polymer in a second mixing device.
