Abstract:
An unsaturated carboxylate mixture, which comprises at least two unsaturated carboxylates, which are represented by the following general formula (1): wherein:R1 and R2 independently of each other represent a hydrogen atom or a saturated aliphatic hydrocarbon group; R3 represents a hydrogen atom, a methyl group, or a saturated aliphatic hydrocarbon group other than the methyl group; n is an integer of not smaller than 1; and X represents wherein: R4 to R9 independently of each other represent a hydrogen atom or an alkyl group; wherein the unsaturated carboxylate mixture comprises a 1-mol adduct of n=1 in general formula (1) and a 2-mol adduct of n=2 in general formula (1) and/or a 3-mol adduct of n=3 in general formula (1) as essential components; wherein the ratio of the 1-mol adduct to the total of the 2-mol adduct and the 3-mol adduct satisfies the following inequality: (1-mol adduct)/{(2-mol adduct)+)3-mol adduct)}&gE;1 (molar ratio).
