Abstract:

Polymer dispersions in aqueous media form binders for pretreatments, coatings and images on substrates. The polymer includes polyamide segments and may have a high percentage of tertiary amide linkages, which facilitates film formation at temperature convenient to textiles and nonwovens. The polyamides are linked with reactions with polyisocyanates (which forms urea linkages if the other reactant is an amine or a urethane linkage if the other reactant is a hydroxyl group).
