CURING ACCELERATOR FOR OXIDATION POLYMERIZATION TYPE UNSATURATED RESIN, PRINTING INK, AND COATING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a curing accelerator for an oxidation polymerization type unsaturated resin, which has a curing performance equal to or higher than an excellent curing performance of a cobalt metal soap, without using a cobalt metal soap that causes worries about influences on a human body, and which has high solubility with an organic solvent and excellent versatility such that the curing accelerator can be used outdoors, and to provide a printing ink and a coating material using the above accelerator.SOLUTION: The curing accelerator for an oxidation polymerization type unsaturated resin comprises: a fatty acid iron salt (A) or an iron complex (B) containing aβ-diketoester (b1), aβ-diketone (b2), or aβ-dicarboxylate (b3); and a salen-based compound (C). The printing ink and the coating material use the above curing accelerator.
