There is provided a highly versatile curing accelerator for an oxidative polymerization-type unsaturated resin. There are also provided a printing ink and a coating material that use the above curing accelerator. Specifically, the curing accelerator for an oxidative polymerization-type unsaturated resin that is used contains a fatty acid manganese salt (A) and a compound (B) represented by formula (1) below, n n(wherein R 1 and R 4 are each a hydrogen atom, a hydrocarbon group, a hydrocarbonoxy group, or an amino group, R 2 and R 5 are each a hydrogen atom, a hydrocarbon group, a hydrocarbonoxy group, a hydrocarbonoxycarbonyl group, a cyano group, a nitro group, or a halogen atom, R 3 and R 6 are each a hydrogen atom or a hydrocarbon group, and R 7 is a divalent hydrocarbon group, and wherein R 1 and R 2 may form a ring, and R 4 and R 5 may form a ring). |
