An object of the present invention is to provide a curing accelerator for an oxidative polymerization-type unsaturated resin which can decrease the amount of use of a cobalt metal soap and which has curing performance equal to or higher than the excellent curing performance of a cobalt metal soap, and also provide a printing ink and a coating material using the curing accelerator. The present invention provides a curing accelerator, and a printing ink and a coating material containing the curing accelerator, the curing accelerator including a fatty acid manganese salt (A), an aminoalcohol (B) represented by general formula (1) below, and at least one fatty acid metal salt (C) selected from the group consisting of a fatty acid bismuth salt, a fatty acid zirconium salt, a fatty acid barium salt, and a fatty acid iron salt.
摘要:
The invention relates to free-radical polymerization and free-radical cross-linking and more particularly provides a process of free-radical polymerization or cross-linking wherein at least one polymerizable monomer or at least one compound to be cross-linked is contacted in the presence of at least one selected organic peroxides, characterized in that the organic peroxide is prepared continuously by an ex situ process with the aid of a closed plate exchanger. In the process according to the invention, it's possible to introduce the above selected organic peroxide continuously during the polymerization or cross-linking reaction.
