Abstract
Aldimines of formula (I) that are particularly suitable as latent hardeners in curable compositions, particularly compositions having one or two-component isocyanate groups. Due to the presence of the reactive group, they can be converted to compounds of formulas (X) and (XII) having aldimine groups. The aldimines, or the aldimine compounds, can be used primarily in adhesive and sealant materials, but also in coatings, and can be produced easily from readily available source materials, and have good thermal stability. The tertiary amino group thereof has a surprisingly low alkalinity and can in some cases have a catalytic effect in chemical reaction systems.
