  • Surfactantless latex compositions
    Publication number: 20030045625
    Abstract: The present invention relates to surfactantless latex compositions. More particularly, the present invention pertains to surfactantless latex compositions comprising sulfo-polyester polymers wherein the compositions have a continuous phase comprising water, diol, polyol or a mixture thereof. Still further, the present invention provides methods of making polymer blends comprising a condensation polymer and a latex polymer whereby the latex polymer is derived from a surfactantless latex composition comprising sulfo-polyester polymers. Polymer blends made by such methods are also provided.
    Type: Application

  • Monomeric dye inkjet printing ink formulations for invisible marking / identification
    Publication number: 20020107302
    Abstract: This invention pertains to aqueous-based ink formulations for inkjet printing of invisible markings on the surface of articles for identification, authentication, sorting, etc. The ink formulations contain at least one near infrared monomeric (as opposed to copolymerized) dye which has been previously dispersed or dissolved in water, glycols, aliphatic alcohols, and are useful for printing by both Continuous inkjet (CIJ) and Drop-on-demand (DOD) methods. This invention also demonstrates the enhanced ability to formulate said inkjet ink formulations when a small amount of water-dissipatible sulfopolyester/amide is added. Also, melt extrusion blending is demonstrated to be an alternative manufacturing process for premixing current Eastman ClirCode™ copolymerizable dyes with the water-dissipatible sulfopolyesters without need for more expensive polymer process manufacturing steps.

  • Sulfopolymers as emulsion stabilizers with improved coagulum level
    Patent number: 6255366
    Abstract: The invention provides a process for preparing a water dispersed polymer blend, comprising the steps of: (I) mixing (a) water; (b) at least one ethylenically unsaturated monomer; (c) at least one branched water-dispersible sulfopolymer; and (II) polymerizing the ethylenically unsaturated monomer within the mixture to provide the water dispersed polymer blend.
