May 21, 1997

Appl. No.:

8/861436

Inventors:

Martha Jean Collins - Blountville TN
Glen Dennis Shields - Kingsport TN
Rebecca Reid Stockl - Kingsport TN
James Wayne Taylor - Kingsport TN

Assignee:

Eastman Chemical Company - Kingsport TN

International Classification:

C08K 304

US Classification:

524502

Abstract:

A water-based ink composition is described. The ink composition contains a pigment and a polymer latex. The polymer latex may be a polymeric (polyamino) enamine latex or a mixture of a polymeric (polyamino) enamine latex and an acetoacetoxy-functional polymer latex. The inks are particularly useful as laminating and surface-printing inks. Methods of printing are also described.

US Classification:

523501

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. Such acrylic-modified waterborne alkyds are useful in a variety of coating compositions.

International Classification:

C08L 6700

US Classification:

524513

Abstract:

This invention provides the preparation of water-dispersible polyester/acrylic hybrids via a two-stage emulsion polymerization process. For example, methacrylic acid and/or 2-hydroxyethyl methacrylate are copolymerized with styrene/acrylic monomers to yield a relatively hydrophilic and hydro-plasticized first stage. Subsequent additions of hydrophobic monomers to this first stage "seed" results in an inversion of the latex such that the more hydrophilic first stage is at the particle surface. This results not only in improved stability of the resulting latex without the use of additional surfactants, as evidenced by the production of reduced amounts of coagulum, while it also offers relatively low minimum filming temperatures due to the hydroplasticization of the shell of the particle. Furthermore, the use of the water-dispersible polyester results in extremely fine latex particle sizes which can significantly enhance coating properties such as film gloss and clarity.
