ABSTRACT:
A thermosetting coating composition contains an acid-curable amino resin and from 0.1 to 10 percent by weight of a blocked sulphonic acid calculated on the weight of amino resin. In order to reduce the electric conductivity of the composition after a prolonged pot-life, a sulphonic acid oximate is used as the blocked acid.
The compositions are advantageous for coating a substrate by electrostatic spraying.
