Abstract
Abstract Aqueous inks containing 1,2-alkyl of from C4 to C10 diols, specifically 1,2-hexanediol or 1,2-pentanediol are employed in jet inks. Two such inks of different colors applied side-by-side to paper do not bleed and therefore give excellent image definition. The diols are not flammable, odorous or highly volatile.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
76 words
An ink for inkjet printing comprising a polar vehicle, a dye soluble in said vehicle and a 1,2-alkyl diol of from 4 to 10 carbon atoms forming the alkyl; said diol being in an amount of at least in the order of magnitude of 0.1% by weight when said carbon atoms are 10 and 12.5% by weight when said carbon atoms are 4 and intermediate said amounts when said carbon atoms are from 5 to 9.
Claim 2
Dependent Claim
76 words
An ink for inkjet printing comprising a polar vehicle, a dye soluble in said vehicle and a 1,2-alkyl diol of from 4 to 10 carbon atoms forming the alkyl; said diol being in an amount of at least in the order of magnitude of 0.1% by weight when said carbon atoms are 10 and 12.5% by weight when said carbon atoms are 4 and intermediate said amounts when said carbon atoms are from 5 to 9.
Claim 3
Dependent Claim
12 words
The ink as in claim 1 in which said diol is 1,2-hexanediol.
Claim 4
Dependent Claim
12 words
The ink as in claim 1 in which said diol is 1,2-pentanediol.
Claim 5
Dependent Claim
21 words
The ink as in claim 3 in which said 1,2-pentanediol is in amount of at least about 7.5 percent by weight.
Claim 6
Dependent Claim
29 words
The ink as in claim 1 in which said alkyl 1,2 diol is in amount of at least about 1 percent by weight when said carbon atoms are 8.
Claim 7
Dependent Claim
21 words
The ink as in claim 2 in which said 1,2-hexanediol is in amount of at least about 2.5 percent by weight.
Claim 8
Dependent Claim
101 words
A process of multi-color printing comprising printing on paper from a first ink of one color and a second ink of a different color on a first region with said first ink and on a second region in close lateral proximity to said first region in close proximity in time to said printing on said first region with said second ink, each of said inks being an aqueous ink containing at least one dye to provide said color and a 1,2-alkyl diol of from 4 to 10 carbon atoms forming the alkyl in amount to prevent lateral bleeding of said inks.
Claim 9
Dependent Claim
101 words
A process of multi-color printing comprising printing on paper from a first ink of one color and a second ink of a different color on a first region with said first ink and on a second region in close lateral proximity to said first region in close proximity in time to said printing on said first region with said second ink, each of said inks being an aqueous ink containing at least one dye to provide said color and a 1,2-alkyl diol of from 4 to 10 carbon atoms forming the alkyl in amount to prevent lateral bleeding of said inks.
Claim 10
Dependent Claim
12 words
The process as in claim 1 in which said diol is 1,2-hexanediol.
Claim 11
Dependent Claim
12 words
The process as in claim 1 in which said diol is 1,2-pentanediol.
