Abstract

Soft feel lacquers comprising water dilutable binders A which possess functional groups, selected from hydroxyl, amino and carboxyl groups, and of curing agents B which have functional groups capable of reacting with the functional groups of the components A, and forming chemical bonds as cross-linking sites, wherein at least one of the components A and B contains a sufficient quantity of aromatic constituent units to ensure that the mass fraction of the aromatic constituent units in relation to the solid matter in the combination of binder and curing agent is not less than 3%.
