Abstract:
A lignin composition containing two or more compounds represented by the following formula (1), where the total content of the compounds is 0.06% by mass or more:
where in the formula, Ra is a hydrogen atom, a methyl group, an ethyl group, a furyl group, a hydroxymethylfuryl group, a hydroxyphenyl group, a hydroxymethoxyphenol group, or a hydroxydimethoxyphenol group; Rc1 and Rc2 are independently a hydroxyl group, an alkoxy group, an amino group, or a thiol group; R11 to R20 are independently a hydrogen atom, a hydroxyl group, a hydrocarbon group including 1 to 15 carbon atoms, a hydrocarbon ether group including 1 to 15 carbon atoms, or a group containing a carbonyl group.
