  • Patent number: 6417267
    Abstract: This invention provides the composition, preparation, and end-use of waterborne crosslinking technology based compositions prepared from water-based latexes. The invention provides a water-based latex comprising dispersed, waterborne amino-functional polymer particles; dispersed, waterborne acetoacetoxy-functional polymer particles; and water. In a preferred embodiment, a latex of the invention comprises dispersed, waterborne polymeric (polyamino)enamine (PPAE) particles; dispersed, waterborne acetoacetoxy-functional polymer particles; and water. The PPAE is the reaction product of a surfactant-stabilized acetoacetoxy-functional polymer (SAAP) and a poly(alkylenimine). The water-based latexes of the invention provide stable emulsions containing a blend of waterborne polymer particles which undergo crosslinking upon film formation. The latex films or coatings may be cured at ambient temperatures or may be thermally cured.

  • Patent number: 6262149
    Abstract: A water-based latex of an acrylic-modified waterborne alkyd dispersion in water is described. The acrylic-modified waterborne alkyd is a hybrid resin prepared by the polymerization of at least one ethylenically unsaturated monomer in the presence of a waterborne alkyd having at least one pendant sulfonate functionality. The ethylenically unsaturated monomer may also be a latent oxidatively functional (LOF) acrylic monomer. Preparation of the latexes may be achieved by emulsion polymerization of at least one ethylenically unsaturated monomer in the presence of a waterborne alkyd having at least one pendant sulfonate functionality. Preparation of hybrid latexes which contain latent oxidative functional (LOF) acrylic monomers may also be achieved by emulsion polymerization of at least one LOF acrylic monomer in the presence of a waterborne alkyd having at least one pendant sulfonate functionality whereby the latent oxidative functionality of the acrylic polymer survives polymerization.

  • Patent number: 5554675
    Abstract: A composition useful in printing inks exemplified as comprising:(1) from about 4 to about 80% by weight of one or more polyester materials having an acid component of from about 75 to about 84 mole % isophthalic acid and conversely from about 25 to about 16 mole % 5-sodiosulfoisophthalic acid, and having a glycol component of from about 45 to about 60 mole % diethylene glycol and conversely from about 55 to about 40 mole % 1,4-cyclohexanedimethanol or ethylene glycol or mixtures thereof;(2) from about 1.0 to about 60% by weight of pigment material;(3) from about 0.05 to about 30% by weight of a nonionic, polyether type property modifier; and(4) from substantially none to about 90% by weight of water.

  • Patent number: 5039339
    Abstract: Disclosed is a novel blend of a water-dissipatable polyester material and an acrylic polymer. The acrylic polymer must be compatible with the polyester and can be optionally styrenated. The polyester is exemplified in having an acid component of from about 75 to about 84 mole % isophthalic acid and conversely from about 25 to about 16 mole % 5-soldiosulfoisophthalic acid, and having a glycol component of from about 45 to about 60 mole % diethylene glycol and conversely from about 55 to about 44 mole % 1,4-cyclohexanedimethanol or ethylene glycol or mixtures thereof.The polymer blends are useful for preparing ink compositions having improved block resistance and water resistance.

  • Patent number: 4996252
    Abstract: Disclosed is a novel blend of a water-dissipatable polyester material and an acrylic polymer. The acrylic polymer must be compatible with the polyester and can be optionally styrenated. The polyester is exemplified in having an acid component of from about 70 to about 84 mole % isophthalic acid and conversely from about 25 to about 16 mole % 5-sodiosulfoisophthalic acid, and having a glycol component of from about 45 to about 60 mole % diethylene glycol and conversely from about 55 to about 40 mole % 1,4-cyclohexanedimethanol or ethylene glycol or mixtures thereof.The polymer blends are useful for preparing ink compositions having improved block resistance and water resistance.

  • Patent number: 4847316
    Abstract: Compositions useful as printing inks or as dry or wet concentrates for the preparation of inks, comprising substantially homogenous blends of from about 0.1 to about 50.0 wt. % water dispersible polyurethane, and conversely from about 99.9 to about 50.0 wt. % water dispersible polyester, and preferably containing from about 1.0 to about 95.0 wt. % of a solvent system comprising water or water admixed with cosolvent, the cosolvent comprising up to about 30.0 wt. % of the solvent system. These blends show exceptionally marked improvements in certain physical properties such as: stability of viscosity to ambient and process conditions; linearity of viscosity change with water dilution; consistency of viscosity for a great variety of pigments; and greatly improved shelf-life (no significant polymer segregation of layering). Such properties greatly enhance the utility of these blends for use in pigmented or dyed printing inks and in other substrate coating formulations which may or may not contain colorants.
