Methods for the reduction of bleeding of lignosulfonates from lignosulfonate-treated substrates |
| abstract |
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. |
