Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
46 words
An ink comprising: (a) a binder comprising shellac or copal, (b) a volatile component comprising water and a solvent for the binder, with the ratio of water to solvent being at least 1:1, (c) a base, (d) a water-reducible titanium ester chelate, and (e) a colorant.
Claim 2
Dependent Claim
46 words
An ink comprising: (a) a binder comprising shellac or copal, (b) a volatile component comprising water and a solvent for the binder, with the ratio of water to solvent being at least 1:1, (c) a base, (d) a water-reducible titanium ester chelate, and (e) a colorant.
Claim 3
Dependent Claim
15 words
The ink of claim 1 wherein the binder is a mixture of shellac and copal.
Claim 4
Dependent Claim
12 words
The ink of claim 2 wherein the mixture is formed by coprecipitation.
Claim 5
Dependent Claim
16 words
The ink of claim 1 wherein the ratio of water to solvent is at least 3:1.
Claim 6
Dependent Claim
19 words
The ink of claim 1 wherein the base is selected from the group consisting of ammonia and volatile amines.
Claim 7
Dependent Claim
69 words
The ink of claim 1 wherein the titanium chelate has the formula: ##STR2## wherein R and R 1 are C 2 -C 10 aliphatic hydrocarbyl groups substituted with at least one electron donor group chosen from --OH, --NH 2 , substituted amino or C═O, and R 2 and R 3 are chosen from the same group as R and R 1 plus --H and C 2 -C 8 alkyl.
Claim 8
Dependent Claim
16 words
The ink of claim 1 having a bond strength of at least 200 grams per inch.
Claim 9
Dependent Claim
25 words
Plastic film printed with the ink of claim 1 and laminated to another substrate, with the ink being sandwiched between the film and the substrate.
Claim 10
Dependent Claim
59 words
In an ink comprising a binder, a colorant, a base and a volatile component comprising water and a solvent for the binder, with the ratio of water to solvent being at least 1:1, the improvement wherein the binder comprises shellac or copal and the ink includes a bond-improving compound which is a water-reducible titanium ester chelate stable in water.
Claim 11
Dependent Claim
59 words
In an ink comprising a binder, a colorant, a base and a volatile component comprising water and a solvent for the binder, with the ratio of water to solvent being at least 1:1, the improvement wherein the binder comprises shellac or copal and the ink includes a bond-improving compound which is a water-reducible titanium ester chelate stable in water.
