Abstract
Abstract In has been desired to employ adhesion promoters in printing inks to promote the adhesion of the ink to a plastic substrate but hitherto the available adhesion promoters have tended to discolor the ink and in certain cases to produce an ink containing a somewhat objectionable odor. A new printing ink has been developed which is based on a polymeric binder, a solvent therefor and an adhesion promoting agent which is the reaction product of a titanium orthoester and either a monoalkyl phosphate or a dialkyl phosphate or a mixture thereof in such proportions that the molar ratio of titanium to phosphate expressed as Ti:P is from 4:1 to 1:2.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
59 words
An ink for marking a plastic substrate, the ink containing an adhesion promoting agent which comprises the reaction product of a titanium orthoester and a compound selected from the group consisting of monoalkyl phosphates, dialkyl phosphates and mixtures thereof wherein said reaction product has a molar ratio of titanium to phosphate expressed as Ti:P of from 4:1 to 1:2.
Claim 2
Dependent Claim
59 words
An ink for marking a plastic substrate, the ink containing an adhesion promoting agent which comprises the reaction product of a titanium orthoester and a compound selected from the group consisting of monoalkyl phosphates, dialkyl phosphates and mixtures thereof wherein said reaction product has a molar ratio of titanium to phosphate expressed as Ti:P of from 4:1 to 1:2.
Claim 3
Dependent Claim
14 words
The ink of claim 1, wherein said Ti:P ratio is from 2:1 to 1:1.5.
Claim 4
Dependent Claim
28 words
The ink of claim 1, wherein the titanium orthoester has the general formula Ti(OR) 4 in which R represents an alkyl group containing up to 8 carbon atoms.
Claim 5
Dependent Claim
17 words

Claim 18
Independent Claim
63 words
A method of improving adhesion between an ink and a plastic substrate to which the ink is applied, comprising adding to the ink the reaction product of a titanium orthoester and a compound selected from the group consisting of monoalkyl phosphates, dialkyl phosphates and mixtures thereof, wherein the reaction product has a molar ratio of titanium to phosphate of from 4:1 to 1:2.
Claim 19
Independent Claim
63 words
