Claims15
An electrostatic ink composition comprising:
- a carrier liquid;
- aluminium stearate particles;
- and
- an aluminium stearate binding agent dissolved in the carrier liquid, wherein the aluminium stearate binding agent comprises an acidic binding group which is bound to an aluminium stearate particle.
A method of preparing an electrostatic ink composition, the method comprising combining aluminium stearate and an aluminium stearate binding agent comprising an acidic binding group in the presence of a carrier liquid to react the aluminium stearate and aluminium stearate binding agent such that the acidic binding group binds to the aluminium stearate, wherein the aluminium stearate binding agent is dissolved in the carrier liquid.
An electrostatic printing method comprising:
- providing an electrostatic ink composition;
- contacting the electrostatic ink composition with a latent electrostatic image on a surface to create a developed ink image;
- transferring the developed ink image to a print substrate, the electrostatic ink composition comprising:
- a carrier liquid;
- aluminium stearate particles;
- and
- an aluminium stearate binding agent dissolved in the carrier liquid, wherein the aluminium stearate binding agent comprises an acidic binding group which is bound to an aluminium stearate particle.
