Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
47 words
A water-based fast-drying ink composition comprising: (a) a water-based polymer prepared by an emulsion polymerization technique, having a Tg of about 50° C. to 120° C. or higher, (b) a surfactant in an amount of about 15 to 50 percent by weight solids of the ink composition.
Claim 2
Dependent Claim
47 words
A water-based fast-drying ink composition comprising: (a) a water-based polymer prepared by an emulsion polymerization technique, having a Tg of about 50° C. to 120° C. or higher, (b) a surfactant in an amount of about 15 to 50 percent by weight solids of the ink composition.
Claim 3
Dependent Claim
30 words
The composition of claim 1 wherein the water-based polymer is an emulsion polymer of solids content greater than 20 percent by weight and a viscosity of less than 50 poises.
Claim 4
Dependent Claim
19 words
The composition of claim 2 wherein the emulsion polymer is prepared by free radical-initiated polymerization of ethylenically unsaturated monomers.
Claim 5
Dependent Claim
18 words
A composition of claim 3 wherein the surfactant comprises an anionic surfactant in combination with a nonionic surfactant.
Claim 6
Dependent Claim
18 words
The composition of claim 4 wherein the nonionic surfactant is an alkyl polyoxyalkylene polyether or alkylaryl polyoxyalkylene polyether.
Claim 7
Dependent Claim
25 words
The composition of claim 1 wherein the surfactant is present in an amount of 15 to 30 percent by weight based on total resin solids.
