Official abstract text for this publication.
A method for producing a resin for ink which includes reacting a lignin, a phenol, and an aldehyde so as to obtain a lignin-containing resol phenolic resin; and reacting the obtained lignin-containing resol phenolic resin with a rosin-based resin, and polyhydric alcohol.
Opening claim text (preview).
1 . A method for producing a resin for ink, the method comprising: reacting a lignin, a phenol, and an aldehyde so as to obtain a lignin-containing resol phenolic resin; and reacting the obtained lignin-containing resol phenolic resin with a rosin-based resin, and a polyhydric alcohol. 2 . The method for producing a resin for ink according to claim 1 , comprising: producing the lignin-containing resol phenolic resin by allowing a phenol-modified lignin obtained after allowing the lignin to react with the phenol under the presence of an acid catalyst to react with the aldehyde under the presence of an alkali catalyst. 3 . The method for producing a resin for ink according to claim 1 , wherein the lignin is modified with acetic acid.
