    • The invention concerns a composition for providing a substrate, after said substrate has been coated, with barrier properties to oils and greases, and complementarily to water. The invention is characterised in that it is obtainable by dispersion, at a temperature ranging between room temperature and about 70null C., of at least a film-forming gum or resin, not water-soluble and solubilized in at least a water-miscible solvent, in an aqueous solution containing at least a water soluble and lipophobic film-forming compound selected among proteins, polysaccharides and their mixtures, said composition having a temperature ranging between room temperature and about 70null C. The invention also concerns a method for preparing said composition, kits containing same, and a method for providing a substrate with barrier properties, and their uses, in particular for making packages and particularly packages for foodstuff.

    • This invention relates to paper sizing compositions comprised of at least one sizing agent selected from ASA, AKD and rosin where the at least one sizing agent is emulsified in water, at least one emulsion stabilizer, and from about 0.01% to about 15% by weight of at least one hydrophobic substance, based on the total weight of sizing agent present, provided that the hydrophobic substance is not highly alkoxylated. The sizing promotion efficiency of the paper sizing compositions, as determined by at least one method selected from the Cytec size testing method, the Hercules size testing method, and the Cobb size testing method, is greater than or equal to about 4. Exemplary hydrophobic substances include fatty acid esters, triglycerides, hydrocarbons, esters and/or amides derived from ASA, silicone oils, alcohols, and stearic anhydride. The invention also relates to methods for sizing paper products with these paper sizing compositions and paper or paperboard treated with these sizing compositions.
    • 本发明涉及由至少一种选自ASA,AKD和松香的上浆剂组成的纸浆施胶组合物,其中至少一种施胶剂在水中乳化,至少一种乳化稳定剂和约0.01重量%至约15重量% 的至少一种疏水性物质,基于存在的施胶剂的总重量,条件是疏水性物质不是高度烷氧基化的。 通过选自Cytec尺寸测试方法,Hercules尺寸测试方法和Cobb尺寸测试方法中的至少一种方法测定的纸浆施胶组合物的施胶效果大于或等于约4.示例性疏水物质 包括衍生自ASA,脂肪酸酯,甘油三酸酯,烃,酯和/或酰胺衍生自ASA,硅油,醇和硬脂酸酐。 本发明还涉及用这些上胶组合物和用这些施胶组合物处理的纸或纸板来调整纸制品的方法。
