Abstract: Novel alkoxy titanium(IV)-chelates are used to modify printing inks based on nitrocellulose or other cellulose ester derivatives. The novel chelates comprise citric acid alkyl esters as chelate formers.

A further advantage of the novel chelates resides in that they do not enter into alteration effects with antioxidants based on phenol, so that they can also be used for printing inks which are to be applied to polymeric substrates containing such antioxidants without the occurence of discoloration.
