Abstract

Compounds containing carbodiimide units and carboxyl or carboxylate groups (compounds V), derived froma) aliphatic or araliphatic C4 to C20 polyisocyanates (component a)b) amino carboxylic acids or amino carboxylic salts (component b) andc) if desired, further compounds which carry groups able to react with isocyanate groups in an addition reaction (component c)d) if desired, other isocyanates (component d), the carbodiimide units deriving essentially exclusively from the isocyanate groups of component (a).
