wherein R1 to R3 each independently represent a hydrogen atom or a C1-4 alkyl group, and an amine compound represented by the following formula (2):
wherein R10, R11, R12, R13 and R14 each independently represent a hydrogen atom, a C1-4 alkyl group, a hydroxy group, a hydroxymethyl group, a 2-hydroxyethyl group or a C1-4 alkoxy group,
a and b are each independently 0 or 1 and satisfy the relation a+b=1, and
R15 is a hydrogen atom, a C1-4 alkyl group, a methoxymethyl group, a methoxyethoxymethyl group or a 2-hydroxyethyl group.
