The present invention provides a printing ink dryer including a fatty acid manganese salt (A) and an aminoalcohol (B) represented by general formula (1) below. The printing ink dryer exhibits drying performance equivalent to or higher than the excellent drying performance possessed by cobalt metal soaps with using a smaller amount of a cobalt metal soap concerned about the influences on human bodies or without using the cobalt metal soap.
(In the formula, R 1 and R 2 each independently represent a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, X 1 and X 2 each independently represent an alkylene group having 2 to 6 carbon atoms, and Y represents -NR 3 - (wherein R 3 represents a hydrogen atom or an alkyl group having 1 to 6 carbon atoms) or an oxygen atom.) |
