LIGNIN DERIVATIVE COMPOUND, LIGNIN RESIN, LIGNIN RESIN COMPOSITION, AND METHOD FOR PRODUCING LIGNIN DERIVATIVE COMPOUND

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive lignin resin.SOLUTION: There is provided a lignin derivative compound which has such a chemical structure that two or more hydroxy groups of lignin or lignophenol are substituted with an aminoalkoxy group having a primary amino group. There is also provided a lignin resin obtained by reaction of a polyvalent epoxy compound having two or more epoxy groups in the molecule, and a polycarboxylic acid having two or more carboxyl groups in the molecule or a polycarboxylic anhydride having two or more acid anhydride groups in the molecule.SELECTED DRAWING: None
