Initiator system for radiation curable compositions, radiation curable

A new initiator system for radiation curable compositions is disclosed. In said system there are incorporated:

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.

Thermosetting coating composition containing a blocked acid catalyst

Novel triazine derivatives which are with cyanoacetic acid, derivatives of cyanoacetic acid or malodinitrile substituted s-triazines and which provide stabilizers against ultraviolet radiation for organic polymers such as polyvinyl chloride or copolymers of polyvinyl chloride or polypropylene are obtained by reacting the corresponding chloro-s-triazinyl derivatives with sodium hydride or a metal lower alcoholate in an organic solvent, and isolating the resulting product by acidification.
