The invention relates to a hydrophilically modified multifunctional amine AC which has more than one primary amino group per molecule, and at least one group per molecule derived from the reaction of an epoxide group with a reactive group selected from the group consisting of secondary amino groups &#x3e;NH, hydroxyl groups &#x2014;OH, mercaptan groups &#x2014;SH, amide groups &#x2014;CO&#x2014;NHR, where R can be hydrogen or an alkyl group having from one to twelve carbon atoms, hydroxyester groups, and acid groups, particularly carboxyl groups &#x2014;COOH, sulphonic acid groups &#x2014;SOH, and phosphonic acid groups &#x2014;POH, and preferably, also moieties which are compatible with an epoxy resin, as well as a process for its preparation, and a method of use thereof.

Multifunctional primary amine, process for its preparation, and use thereof

The invention relates to a hydrophilically modified multifunctional amine AC which has more than one primary amino group per molecule, and at least one group per molecule derived from the reaction of an epoxide group with a reactive group selected from the group consisting of secondary amino groups &#x3e;NH, hydroxyl groups &#x2014;OH, mercaptan groups &#x2014;SH, amide groups &#x2014;CO&#x2014;NHR, where R can be hydrogen or an alkyl group having from one to twelve carbon atoms, hydroxyester groups, and acid particularly carboxyl groups &#x2014;COOH, sulphonic acid groups &#x2014;SOH, and phosphonic acid groups &#x2014;POH, and preferably, also moieties which are compatible with an epoxy resin, as well as a process for its preparation, and a method of use thereof.

Storage-stable polyurethane dispersions preparable by reacting polydienes A which carry at least two isocyanate-reactive groups, polyols B which carry at least one acid group, polyfunctional isocyanates C and chain extenders D, wherein the acid groups of the polyols B are neutralized to a fraction of from 60 to 95%, processes for preparing them, and their use for producing elastic coatings.

Aqueous polyurethane dispersions containing polybutadiene units

Water dilutable binder for soft feel coating materials, comprising an aqueous dispersion of a hydroxyl-containing polyester-urethane A, preparable by reacting a polyester A1 with hydroxyl groups as functional groups, formed from difunctional or polyfunctional carboxylic acids A11 and difunctional or polyfunctional alcohols A12, with a polyfunctional isocyanate A2, with a compound A3 having at least one isocyanate-reactive group and at least one acid group, an aqueous solution or dispersion of a triazine resin B, wherein the glass transition temperature of the polyester-urethane A is between &minus;70 and &minus;20&deg; C. and wherein the hydroxyl number of the polyester-urethane A is from 10 to 120 mg/g, a process for its preparation, and its use in soft feel coating materials for plastics, metals, glass, wood, textiles, and leather.
