Abstract
The invention encompasses a phase change ink comprising a material of the formula wherein X1, X2, X3 and X4 are segments comprising atoms selected from groups V and VI of the periodic table; wherein at least one R1. and R5 comprises at least 37 carbon units; and wherein R2, R3 and R4 each comprise at least one carbon unit. The invention further encompasses a composition of matter, as well as methods of reducing coefficients of friction of phase change ink formulations.

A phase change ink, comprising:
- a material of the formula
- wherein X1, X2, X3, and X4 are segments which each comprise an atom selected from groups V and VI of the periodic table;
- the atoms selected from groups V and VI of the periodic table in segments X1, X2, X3, and X4 being the same or different than one another;
- wherein at least one of R1 and R5 comprises at least 40 carbon units;
- and wherein R2, R3 and R4 each comprise at least one carbon unit;
- and
- a colorant.
A phase change ink, comprising:
- a material of the formula
- wherein n is an integer greater than or equal to 39 and less than or equal to 99;
- and wherein R1, R2 and R3 each comprise at least one carbon unit;
- and
- a colorant.
A method of reducing a coefficient of friction associated with a phase change ink formulation, comprising:
- providing a material within the ink formulation, the material having the formula
- wherein X1, X2, X3, and X4 are segments which each comprise an atom selected from groups V and VI of the periodic table;
- the atoms selected from groups V and VI of the periodic table in segments X1, X2, X3, and X4 being the same or different than one another;
- wherein at least one of R1 and R5 comprises at least 40 carbon units;
- and wherein R2, R3 and R4 each comprise at least one carbon unit;
- and
- providing a surface of a printed portion of the ink having a lower coefficient of friction relative to glass than if the material were not provided in the ink formulation.
A composition of the formula
- wherein X1, X2, X3, and X4 are segments which each comprise an atom selected from groups V and VI of the periodic table;
- the atoms selected from groups V and VI of the periodic table in segments X1, X2, X3, and X4 being the same or different than one another;
- wherein R1 and R5 each comprise at least 40 carbon units and consist essentially of carbon and hydrogen, and wherein R2, R3 and R4 each comprise at least one carbon unit and consist essentially of carbon and hydrogen.
