Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
72 words
In a process for information recording comprising producing a fine jet of colored aqueous liquid, directing the jet of colored liquid onto a recording medium, modulating the density of the applied jet by an electric field in accordance with the information to be recorded, the improvement comprising the presence as a humectant of an ethylene oxide adduct of at least one acetylenic diol in the absence of any glycol or glycol ether.
Claim 2
Dependent Claim
72 words
In a process for information recording comprising producing a fine jet of colored aqueous liquid, directing the jet of colored liquid onto a recording medium, modulating the density of the applied jet by an electric field in accordance with the information to be recorded, the improvement comprising the presence as a humectant of an ethylene oxide adduct of at least one acetylenic diol in the absence of any glycol or glycol ether.
Claim 3
Dependent Claim
21 words
The process of claim 1 wherein said ethylene oxide adduct of an acetylenic diol is the ethylene oxide adduct of 2,4,7,9-tetra-methyl-5-decyne-4,7-diol.
Claim 4
Dependent Claim
39 words
An ink composition for use in jet printing comprising an aqueous solution of a water-soluble dye and a humectant consisting of ethylene oxide adducts of at least one acetylenic diol in the absence of any glycol or glycol ether.
Claim 5
Dependent Claim
39 words
