Titanium(iv)-chelates and the use thereof in printing ink

Abstract From the Canadian patent

The present invention relates to new alkoxy-titanium(IV)chelates and to the use thereof in printing inks based upon nitrocellulose or other cellulose-ester derivatives. The new chelates are characterized in that they contain citricacid alkyl-esters as chelate-formers. Like other titaniumchelates, they delay the known catalytic action of titanium components during cross-linking reactions. When used in printing inks, the new titanium-chelates and alcoholic, solutions thereof, have the advantage of possessing only a small amount of inherent colour, so that they scarcely discolour the printing inks. Another advantage of the new chelates is that they also do not interact with antioxidants based …
