METHOD AND COMPOSITIONS FOR PREVENTING THE AGGLOMERATION OF AQUEOUS PIGMENT DISPERSIONS |
摘要 |
The present invention provides a method of preventing pigment agglomeration upon the addition of an aqueous resin solution to an aqueous pigment dispersion. The present invention further provides a method of stabilizing a pigment dispersion upon the addition of an aqueous resin solution to an aqueous pigment dispersion. Pigment agglomeration is prevented and the pigment dispersion is stabilized by mixing butylated PVP with the pigment dispersion prior to the addition of the resin solution. The present invention further provides an aqueous ink-jet composition for use in aqueous-based ink-jet printers. The composition comprises water, butylated PVP, an aqueous pigment dispersion, a resin and a humectant. The present invention further provides a process for preparing the ink composition. |
