Abstract
The present invention relates to coating compositions which are suitable for the production of heat resistant films and coatings and contain PA1 a) 100 parts by weight of organic compounds having (i) carbodiimide and/or uretoneimine groups and (ii) blocked isocyanate groups, PA1 b) 2 to 100 parts by weight of intramolecular carboxylic acid anhydrides which have a molecular weight of 98 to 500 and may contain free carboxyl groups and PA1 c) 2 to 100 parts by weight of polyhydric alcohols which have a molecular weight of 62 to 400 and a hydroxyl functionality of 2 to 4. The present invention also relates to heat-resistant substrates, in particular for wires, coated with these coating compositions.
