Abstract
Firstly, the invention concerns an organic resin that comprises structural units in its overall composition obtained from: The invention also concerns an aqueous dispersion of said resin and a preparation process as a cross-linkable aqueous composition comprising said resin or dispersion and a polyamine. The resin is used for the preparation of cross-linked polyurethanes without the use of polyisocyanate, in particular in high performance aqueous coatings.
