    摘要： A low viscosity high solids thermosetting coating composition useful in the packaging industry as a barrier coating and overprint varnish, based urea-formaldehyde crosslinking agents and low molecular weight polyols, is provided. These compositions provide rapid cure response and afford coatings having good gloss, clarity, and mar resistance and are non-blocking. The compositions do not contain aromatic solvents and are applicable by gravure or flexographic techniques.

    摘要： A coating composition useful in the packaging industry as a barrier coating and overprint varnish consists essentially ofA. a nitrogen resin crosslinking agent;B. an optional flexibilizing component having a hydroxyl and/or carboxyl group attached thereto selected from the group consisting essentially ofI. a copolymer of at least one monomer selected from the group: styrene, alkyl ester of up to eight carbon atoms of acrylic and methacrylic acids with at least one other monomer selected from the group: acrylic acid, methacrylic acid, itaconic acid, hydroxyethyl acrylate, hydroxypropyl acrylate, hydroxyethyl methacrylate, and hydroxypropyl methacrylate; andIi. an alkyd resin prepared from fatty acid triglycerides, di- and polyols, and di- and polycarboxylic acids and/or anhydrides thereof; andC. a mixture of mono- and di-alkyl esters of phosphoric acid, where the molar ratio of monoester to di-ester is from 4:1 to 1:4 and the esterifying alcohol is selected from alcohols containing from eight to twelve carbon atoms and mixtures thereof and, optionally, phosphoric acid or its lower alkyl esters,Said composition affording, upon cure, a coating of excellent slip properties without any additional slip agents.
