Abstract
Abstract A heterologous ink composition for use in an ink jet apparatus features two miscibly incompatible components made compatible by the use of a common solvent having misability for both aqueously and non-aqueously miscible components. The heterologous ink composition derives its print quality characteristic from the non-aqueously miscible component and its good jetability and samll dot size from its aqueously miscible component.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
86 words
A non-aqueous ink composition for use in an ink jet apparatus, comprising at least one non-aqueously miscible fluid component and at least one aqueously miscible fluid component, said non-aqueously miscible component and said aqueously miscible component being normally immiscible with each other, said composition further comprising a common solvent in which said immiscible fluid components are commonly miscible, said non-aqueously miscible component lending a print quality characteristic to said ink composition, and said aqueously miscible component lending an improved surface tension characteristic to said ink composition.
Claim 2
Dependent Claim
86 words
A non-aqueous ink composition for use in an ink jet apparatus, comprising at least one non-aqueously miscible fluid component and at least one aqueously miscible fluid component, said non-aqueously miscible component and said aqueously miscible component being normally immiscible with each other, said composition further comprising a common solvent in which said immiscible fluid components are commonly miscible, said non-aqueously miscible component lending a print quality characteristic to said ink composition, and said aqueously miscible component lending an improved surface tension characteristic to said ink composition.
