Appl. No.:

10/132721

Inventors:

Martha Jean Collins - Blountville TN
Richard Alvin Martin - Kingsport TN
Rebecca Reid Stockl - Kingsport TN

Assignee:

Eastman Chemical Company - Kingsport TN

International Classification:

C08K 506

US Classification:

524366, 524376, 524377, 524378

Abstract:

The invention relates to an improved water-based polymer coating composition comprising a polymer resin, water and surfactant. As an improvement over prior water-based polymer coating compositions an anionic and/or nonionic surfactant is present in an amount effective to plasticize the coating formed from the composition. A water-based polymer coating composition of the invention is also substantially free from cosolvents. The invention also relates to a method of coating a substrate and a substrate which has been coated with a coating formulation of the invention.

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.

International Classification:

C08F22800
C08F22400

US Classification:

526270

Abstract:

Surfactant-containing acetoacetoxy-functional polymers (SAAP's) are described. The acetoacetoxy-functional polymer may be a surfactant-containing enamine-functional polymer and more preferably a surfactant-containing, polymeric (polyamino)enamine (PPAE). The PPAE is the reaction product of a surfactant-containing acetoacetoxy-functional polymer (SAAP) and a poly(alkylenimine). The polymers may be prepared as waterborne polymer compositions, such as latexes. The waterborne polymer compositions can be prepared with high solids content while maintaining low viscosity. Waterborne polymer compositions containing the polymers of the inventions are useful in a variety of coating formulations such as, for example, paints, inks, sealants, and adhesives. When used in coating formulations, the polymers of the invention provide adhesion and crosslinking in the final film or coating. The film or coating may be cured at ambient temperatures or may be thermally cured.

International Classification:

C08F 2226
C08F12226
C08F22012
C08J 300

US Classification:

526323

Abstract:

This invention provides polymers useful in coating compositions. The polymers are prepared via a free radical polymerization using ethylenically unsaturated monomers. The polymers of this invention possess pendant allylic groups which are capable of effecting free-radical flux when the compositions are applied to a substrate and exposed to oxygen. Coatings formed from preferred compositions possess superior solvent, print, and block resistance.

US Classification:

525293

Abstract:

This invention relates to reactive polymers, e. g. , aqueous emulsion polymers, having pendant flexible or dangling side chains prepared from ethylenically unsaturated carbodiimides, e. g. , carbodiimide (meth)acrylates. The reactive polymers contain ethylenic unsaturation near the surface or in the surface area of the particles that form the polymers, the ethylenic unsaturation being connected to the polymer through the pendant flexible or dangling side chains. This invention also relates to the process for preparing the reactive polymers, to crosslinkable formulations based on the reactive polymers, and to thermoplastic and crosslinked films prepared from the reactive polymers. The reactive polymers are useful as decorative and functional coatings, inks, adhesives, textile coatings and sealants.
