There is provided a highly versatile curing accelerator for an oxidative polymerization-type unsaturated resin that is highly soluble in organic solvents, can be used outdoors, and has a curing performance equal to or higher than the curing performance of cobalt metallic soaps, which are feared to have an influence on the human body, without the use of any cobalt metallic soap. 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,
(wherein R1 and R4 are each a hydrogen atom, a hydrocarbon group, a hydrocarbonoxy group, or an amino group, R2 and R5 are each a hydrogen atom, a hydrocarbon group, a hydrocarbonoxy group, a hydrocarbonoxycarbonyl group, a cyano group, a nitro group, or a halogen atom, R3 and R6 are each a hydrogen atom or a hydrocarbon group, and R7 is a divalent hydrocarbon group, and wherein R1 and R2 may form a ring, and and R5 may form a ring).
本发明提供了一种用于氧化聚合型不饱和树脂的高通用性固化促进剂,它在有机溶剂中的溶解度高,可在室外使用,固化性能等同于或高于恐怕会对人体产生影响的钴金属皂的固化性能,且无需使用任何钴金属皂。此外,还提供了使用上述固化促进剂的印刷油墨和涂层材料。具体地说,所使用的氧化聚合型不饱和树脂固化促进剂含有脂肪酸锰盐 (A) 和下式 (1) 所代表的化合物 (B)、
(其中 R1 和 R4 各为氢原子、烃基、烃氧基或氨基,R2 和 R5 各为氢原子、烃基、烃氧基、烃氧羰基、氰基、硝基或卤素原子,R3 和 R6 各为氢原子或烃基,R7 为二价烃基,其中 R1 和 R2 可形成一个环,R5 可形成一个环)。
