Method for increasing the stability of non-ionic surfactant-containing ink composition
A method for increasing the cloud point and stability of an ink compsn. comprises: (a) providing an ink compsn. contg. solvent, colouring agent, and ethoxylated non-ionic surfactant(s); (b) placing the compsn. in contact with multicellular foam which reacts with the surfactant to form a treated ink...

| description | A method for increasing the cloud point and stability of an ink compsn. comprises: (a) providing an ink compsn. contg. solvent, colouring agent, and ethoxylated non-ionic surfactant(s); (b) placing the compsn. in contact with multicellular foam which reacts with the surfactant to form a treated ink prod. having a greater cloud point than the original compsn.; and (c) extracting the ink prod. from the foam. Also claimed are the following: (1) a method in which in step (c), the foam is compressed to expel the treated ink prod.; (2) a method as in the main claim in which 0.1-30 wt.% solvent, 2-7 wt.% colouring agent, and 0.1-10 wt.% surfactant is used; the original cloud point being 30-50 [deg]C, and the final cloud point being about 60 [deg]C; (3) a method in which the foam is PU foam; (4) a method as in (1) in which the foam is PU foam; and (5) a method as in (2) in which the foam is PU foam. |
