Abstract
Abstract A new organotitanate which is a reaction product of a titanium orthoester and at least a monoalkyl phosphate in which the alkyl group contains up to 6 carbon atoms and in which the total molar ratio P:Ti in the product is less than 2. The monoalkyl phosphates preferably contain up to 5 carbon atoms in the alkyl group and the organotitanate reaction product can also be prepared from a dialkyl phosphate in addition to the monoalkyl phosphate. Most preferably the alkyl group of the titanium orthoester is either an isopropyl group or a butyl group. The new reaction products are of use as adhesion promoters in printing inks.
