Abstract

A resin for ink is obtained by reaction of a lignin, phenols, aldehydes, a rosin-based resin, and polyhydric alcohol.

Claims

exact text as granted — not AI-modified

1 . A resin for ink obtained by reaction of
 a lignin,   phenols,   aldehydes,   a rosin-based resin, and   polyhydric alcohol.   
     
     
         2 . The resin for ink according to  claim 1 , obtained by reaction of
 a lignin-containing resol-type phenolic resin obtained by reaction of the lignin, the phenols, and the aldehydes;   the rosin-based resin; and   the polyhydric alcohol.   
     
     
         3 . The resin for ink according to  claim 2 , wherein
 the lignin-containing resol-type phenolic resin is obtained by allowing   a phenol-modified lignin obtained after allowing the lignin to react with the phenols under the presence of an acid catalyst to react with the aldehydes under the presence of an alkali catalyst.   
     
     
         4 . The resin for ink according to  claim 1 , wherein
 the lignin is modified with acetic acid.   
     
     
         5 . Ink containing a resin for ink according to  claim 1 .
