  • Publication number: 20230167310
    Abstract: The present invention provides a curing catalyst which promotes a reaction between a hydroxyalkyl amide-based curing agent and a carboxy group-containing resin, especially curing of a carboxy group-containing resin-based powder coating material using a hydroxyalkyl amide-based curing agent, and in particular, curing of a polyester resin-based powder coating material. A curing catalyst which promotes a reaction between a carboxy group-containing resin and a compound that has a ?-hydroxyalkyl amide group, said curing catalyst containing a compound that contains, as a metal atom, at least one element selected from the group consisting of Mo, Cr, V, Fe, Co, Ni, Ga, Zr, In, Ba, Ce and Bi. It is preferable that the metal atom is an Mo atom. An Al atom may be included as the metal atom.
