    摘要: According to the present invention, curable compositions comprising (i) one or more polyacid containing at least two carboxylic acid groups, anhydride groups, or salts thereof; (ii), optionally, one or more polyol containing at least two hydroxyl groups; and (iii) one or more reactive β-hydroxyamide group containing polyol, which is the reaction product of a lactone or cyclic ester and an alkanolamine, of the following formula (I):

    in which, R and R" independently represent H, or any monovalent C 1 to C 18 linear or branched alkyl radical, which radical may comprise one or two aryl or cycloalkyl group, one or more hydroxyl, amine, thiol, amide, carboxyl or alkenyl group, or combinations thereof; R' represents either a covalent bond or a divalent C 1 to C 5 alkylene radical where the alkylene radical may bear alkyl group substituents; y is the integer 1 or 2; x is 0 or 1, such that (x + y) =2; wherein the ratio of the number of equivalents of said carboxylic acid groups, anhydride groups, or salts thereof to the number of equivalents of said hydroxyl groups is from 1/0.01 to 1/3. The curable compositions of the present invention provide less corrosive, low energy curing binders. Further, the present invention provides methods to use the compositions as aqueous binders for composites, nonwoven and woven substrates, and the products produced thereby.

    摘要: The invention relates to a method for applying a finishing layer to a textile carrier material. According to the inventive method, a water repellent layer or oil repellent layer, a so-called finishing layer is applied to a carrier material of the group of fibres, tissues and fabrics. The water or oil repellent finishing layer comprises at least two water or oil repellent components. A first component comprises at least one dispersing agent and a second component comprises at least one dispersed phase or a colloid. The dispersing agent and the dispersed phase are present in a gel state. The colloids of the dispersed phase are distributed in the dispersing agent in an anisotropic manner in such a way that the colloids are present in a concentrated form in the region of the finishing surface which forma a phase boundary layer between the finishing layer and the surrounding atmosphere. According to the finishing method and a first step thereof, the dispersion that is present as a colloidal solution is applied to the carrier material and is converted into a gel state in a subsequent step. The components of the dispersion are provided with an inherent capability of self-organisation. Said capability is used for obtaining the anisotropic distribution. The invention also relates to textile articles being provided with the novel water or oil repellent finishing layer. Said articles are equal or superior to products produced according to known finishing methods, with respect to the functional characteristics thereof and on the highest level. Said articles enable the chemicals which are ecologically harmful, might be harmful to health and are conventionally used to be entirely or partially replaced by novel compounds that are not in use until now.
