Abstract:
1. A non-water soluble polymeric surfactant prepared by (a) reacting, with heating, a polymerized/bodied unsaturated oil with 4-5 wt % maleic anhydride until no free maleic anhydride is present; (b) cooling the mixture of (a); (c) adding morpholine to the mixture of (b); (d) holding the mixture of (c) for one hour; (e) heating the mixture of (d) until reaching a zero amine value and a 23-27 acid value; (f) cooling the mixture of (e), wherein said non-water soluble polymeric surfactant improves emulsion stability by reducing droplet size of emulsified water in an emulsion heatset ink comprising the non-water soluble polymeric surfactant.
