Abstract
A method is provided for making thermochromic pigments in microcapsules having unusually small particle sizes.
Claims22
A microcapsule-based pigment comprising microcapsules having a mean by volume particle size diameter of less than 1 micron,
- wherein the microcapsule-based pigment is produced from a water-based emulsion and is combined with an emulsifier in an effective amount to have provided the mean by volume particle size diameter of less than one micron in the water-based emulsion,
- the microencapsulated pigment being in a dewatered state to a concentration of from 5% to 35% moisture.
