Description	Reactions of isothiocyanates (ITCs) in the presence of amino compounds were studied. They led to colored structures via substituted 2-thiohydantoins. Low-molecular colorants isolated and characterized from the model systems were yellow to red diastereomeric dehydrodimers of 2-thiohydantoin derivatives that contain an acidic methylene group are formed in mixtures consisted of ITCs and amino acids with -methylene group in mild acidic to mild alkaline systems. The condensation products of the 2-thiohydantoins with reactive aromatic or heterocyclic carbaldehydes from the Maillard reaction, essential oils etc. comprise a heterogeneous group of mostly yellow colorants. Blue compounds of two types are structurally more complicated structures that arise from N-substituted amino acids and ITCs in alkaline media.
