Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
55 words
In a process for preparing printing inks for the lithographic printing process, the improvement comprising adding as a drier promoter composition, the composition comprising a zirconium salt of at least one organic carboxylic acid containing from 6 to about 30 carbon atoms and an alkali metal or alkaline earth metal perborate to a printing ink.
Claim 2
Dependent Claim
55 words
In a process for preparing printing inks for the lithographic printing process, the improvement comprising adding as a drier promoter composition, the composition comprising a zirconium salt of at least one organic carboxylic acid containing from 6 to about 30 carbon atoms and an alkali metal or alkaline earth metal perborate to a printing ink.
Claim 3
Dependent Claim
19 words
The process of claim 1 wherein the organic carboxylic acids contain from about 6 to about 12 carbon atoms.
Claim 4
Dependent Claim
14 words
