Claims12
A charged particle comprising:
- a titanium oxide particle;
- and
- a composition including one reactive group, the reactive group being bonded to the titanium oxide particle.
A method of forming a microcapsule comprising:
- forming a charged particle by bonding a plurality of compositions to a titanium oxide particle, each of the plurality of the compositions including one reactive group as a substituent;
- forming a dispersion by adding the charged particle to a disperse medium;
- and
- forming a microcapsule by covering the dispersion with a capsule.
