Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
80 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 an effective amount of the internal anhydride of at least one carboxylic acid selected from the group consisting of fatty acids, acetylenic acids, alicyclic acids and aromatic acids.
Claim 2
Dependent Claim
80 words

Claim 3
Dependent Claim
17 words
The process of claim 1 wherein said internal anhydride of at least one carboxylic acid is butyrolactone.
Claim 4
Dependent Claim
50 words
An ink composition for use in jet printing comprising an aqueous solution of a water-soluble direct dye and a humectant consisting of an effective amount of the internal anhydride of at least one carboxylic acid selected from the group consisting of fatty acids, acetylenic acids, alicyclic acids and aromatic acids.
Claim 5
Dependent Claim
50 words
