Abstract
The invention relates to an ink composition, the ink composition including a pinning agent. The pinning agent provides the ink composition with thermogelling behavior. The invention further relates to a pinning agent suitable for an ink composition. The invention further relates to a method for applying an image to a receiving medium using an ink composition including a pinning agent.
Claims10
An ink composition comprising:
- a) an aqueous vehicle;
- b) a colorant;
- c) a water-dispersed resin;
- and
- d) a pinning agent, the pinning agent consisting essentially of a product of a coupling reaction between
- at least two polyether units and
- a linker, the linker comprising at least two linking groups,
- wherein a first one of the at least two polyether units comprises an ethylene oxide moiety (—[CH2CH2O]—) and wherein the second one of said at least two polyether units comprises a —[R1O]— moiety, wherein R1 is an alkyl group comprising 3-7 carbon atoms, and
- wherein each one of the at least two linking groups is capable of reacting with an endgroup of a polyether unit.

Method for preparing an ink composition, the method comprising the steps of:
- a) providing water;
- b) providing a pinning agent, the pinning agent consisting essentially of a product of a coupling reaction between
- at least two polyether units and
- a linker, the linker comprising at least two linking groups,
- wherein a first one of the at least two polyether units comprises an ethylene oxide moiety (—[CH2CH2O]—) and wherein the second one of said at least two polyether units comprises a —[R1O]— moiety, wherein R1 is an alkyl group comprising 3-7 carbon atoms, and
- wherein each one of the at least two linking groups is capable of reacting with an endgroup of a polyether unit;
- c) providing a colorant;
- d) providing a water-dispersed resin;
- and
- e) mixing the water, the pinning agent, the water-dispersed resin and the colorant.
