摘要
The invention relates to thermoplastic compositions in powder form based on polyamide and/or polyetheresteramide and containing resins obtained by polycondensation of aromatic sulphonamide compounds and of aldehydes or of dicarboxylic acids. The invention also relates to a number of processes for obtaining these powders and to their use for coating metal substrates without the need for any adhesion primer.
