US Classification:

524543000

Abstract:

A process for forming an emulsion of an energy-curable component by passing the energy-curable component, water and optionally a surfactant through an in-line mixing zone. The in-line mixing zone can be a static mixing zone or a high shear in-line mixing zone having a rotor-stator assembly. The emulsion can be prepared contemporaneously (just-in-time) with its use.

US Classification:

522 40

Abstract:

A radiation-polymerizable composition contains at least one radiation curable acrylate resin oligomer prepared by reacting an alkoxylated polyol with a first acid component which includes an ethylenically unsaturated carboxylic acid; and a rheology modifier prepared by reacting a diepoxide with a second acid component which includes an ethylenically unsaturated carboxylic acid or reactive derivative thereof in the presence of a polyamide based on a polymerized fatty acid. The ethylenically unsaturated carboxylic acids of the first and second acid components are preferably acrylic acid or methacrylic acids. The diepoxide is preferably a diglycidyl ether such as bisphenol A. Colorants such as pigments or dyes optionally may be incorporated into the composition to form a printing ink which is curable by ultraviolet (UV) or electron beam radiation.

Abstract:

A composition comprising the reaction product of: a) a polycarboxylic member selected from the group consisting of polycarboxylic acids comprised of a diacid having more than about 12 carbon atoms and reactive derivatives thereof (e. g. alkyl esters thereof wherein the alkyl group has from 1 to 4 carbon atoms), b) an ethylenically unsaturated member selected from the group consisting of ethylenically unsaturated mono-carboxylic acids and reactive derivatives thereof, (e. g. alkyl esters thereof wherein the alkyl group thereof has from 1 to 4 carbon atoms), and c) an ethoxylated alkanetriol having an average degree of ethoxylation per hydroxyl of less than about 2 and comprised predominantly of ethoxylated alkanetriol species having one ethoxylate group per hydroxyl. This composition is useful as a polymerizable component, particularly for UV curable coatings and inks.
