Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
39 words
An ink jet printing composition containing a liquid vehicle and a colorant and a surfactant comprising 0.3 to 0.6 wt. % acetylenic polyalkylene oxide and 1 to 4 wt % quasisurfactant penetrant based on the wt. of said composition.
Claim 2
Dependent Claim
39 words
An ink jet printing composition containing a liquid vehicle and a colorant and a surfactant comprising 0.3 to 0.6 wt. % acetylenic polyalkylene oxide and 1 to 4 wt % quasisurfactant penetrant based on the wt. of said composition.
Claim 3
Dependent Claim
19 words

Claim 8
Dependent Claim
54 words
An ink jet printing process, comprising causing an ink jet composition containing a surfactant comprising 0.3 to 6 wt. % acetylenic polyalkylene oxide and 1 to 4 wt. % quasisurfactant penetrant based on the wt. of said composition to be ejected in an imagewise fashion from a thermal ink jet printer onto a substrate.
Claim 9
Dependent Claim
54 words
An ink jet printing process, comprising causing an ink jet composition containing a surfactant comprising 0.3 to 6 wt. % acetylenic polyalkylene oxide and 1 to 4 wt. % quasisurfactant penetrant based on the wt. of said composition to be ejected in an imagewise fashion from a thermal ink jet printer onto a substrate.
