REDUCTION OF BLEEDING OF LIGNOSULFONATES FROM TREATED SUBSTRATES
摘要
<p>The bleeding of lignosulfonates from lignosulfonate-treated substrates when contacted under humid conditions is reduced by rendering the lignosulfonates water-insoluble via reacting them with an amine polymer-epichlorohydrin adduct containing at least one quaternary ammonium group under acidic conditions.</p>
