Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
81 words
A printing ink of low misting properties comprising a dispersion of about 5 to about 30 wt. %, based on the weight of the ink, of a pigment in a vehicle containing about 50 to about 95 wt. %, based on the weight of the vehicle of a hydrocarbon oil and about 0.1 to about 4 wt. %, based on the weight of the ink, of a compound selected from the group consisting of organic acid phosphate, glycerol and propylene carbonate.
Claim 2
Dependent Claim
81 words
A printing ink of low misting properties comprising a dispersion of about 5 to about 30 wt. %, based on the weight of the ink, of a pigment in a vehicle containing about 50 to about 95 wt. %, based on the weight of the vehicle of a hydrocarbon oil and about 0.1 to about 4 wt. %, based on the weight of the ink, of a compound selected from the group consisting of organic acid phosphate, glycerol and propylene carbonate.
Claim 3
Dependent Claim
26 words
The ink of claim 1 wherein the compound is present in an amount of 0.3 to 2 wt. %, based on the weight of the ink.
Claim 4
Dependent Claim
13 words
The ink of claim 1 wherein the compound is an organic acid phosphate.
Claim 5
Dependent Claim
33 words

Claim 8
Dependent Claim
87 words
A printing process for reducing ink misting which comprises utilizing a printing ink comprising a dispersion of about 5 to about 30 wt. %, based on the weight of the ink, of a pigment in a vehicle containing about 50 to about 95 wt. %, based on the weight of the vehicle, of a hydrocarbon oil and about 0.1 to about 4 wt. %, based on the weight of the ink, of a compound selected from the group consisting of organic acid phosphate, glycerol and propylene carbonate.
Claim 9
Dependent Claim
87 words
A printing process for reducing ink misting which comprises utilizing a printing ink comprising a dispersion of about 5 to about 30 wt. %, based on the weight of the ink, of a pigment in a vehicle containing about 50 to about 95 wt. %, based on the weight of the vehicle, of a hydrocarbon oil and about 0.1 to about 4 wt. %, based on the weight of the ink, of a compound selected from the group consisting of organic acid phosphate, glycerol and propylene carbonate.
Claim 10
Dependent Claim
26 words
The process of claim 7 wherein the compound is present in an amount of 0.3 to 2 wt. %, based on the weight of the ink.
