Abstract: There is provided a polyester modifier composition for a cellulose ester resin, including: a polyester resin produced by a reaction between a diol and 1,2-dicarboxycyclohexane. The modifier composition has a number-average molecular weight (Mn) in the range of 350 to 2,000 as measured by gel permeation chromatography (GPC). The polyester resin has a molecular weight of less than 350 constitutes 5% or less by mass of the modifier composition.

Abstract: 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 carboxylates 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, R1 and R2 each independently represent a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, X1 and X2 each independently represent an alkylene group having 2 to 6 carbon atoms, and Y represents —NR3—, wherein R3 represents a hydrogen atom or an alkyl group having 1 to 6 carbon atoms or an oxygen atom.
