Abstract: A radiation curable polyurethane-based binder dispersion includes water and a radiation curable polyurethane dispersed in the water. The polyurethane is formed from: a polyisocyanate; a polyol having a chain with two hydroxyl functional groups at one end of the chain and no hydroxyl groups at an opposed end of the chain, and having a number average molecular weight ranging from about 500 to about 5,000; an acrylate or methacrylate, the acrylate or methacrylate having at least one hydroxyl functional group and having an acrylate functional group or a methacrylate functional group; an alcohol or a diol or an amine having a number average molecular weight less than 600; and a sulfonate or sulfonic acid having one or two amino functional groups.
