Abstract
Disclosed herein are a color capsule composition, which contains a polymer and a plasticizer swelling the polymer so as to allow the capsule particles to easily break and in which the capsule particles have a porous structure that boosts the effects thereof, and a method for preparing the color capsule composition. The preparation method comprises: uniformly mixing a color pigment, a plasticizer and a polymer in a first solvent to produce a first mixture solution; spray-drying the first mixture solution to produce core particles in which the color pigment is covered by the polymer; uniformly mixing the obtained core particles, a functional pigment and a second solvent to produce a second mixture solution; and spray-drying the second mixture solution to produce in which a coating layer of the functional pigment is formed on the outer surface of the polymer.
