The present invention includes: 1) dissolving a first binder in a first solvent; 2) dissolving a dispersing agent in a solution in which the first binder is dissolved; 3) adding charcoal powder to the solution obtained in 2) and performing homogenous mixing to produce a dispersion in which the charcoal powder is bound to the first binder; 4) spray drying the dispersion obtained in 3) to produce a primary capsule from which the first solvent is removed; 5) dissolving a second binder and a softening agent in a second solvent; 6) homogeneously mixing a coloring agent and the dispersing agent with a solution in which the second binder and the softening agent are dissolved; 7) mixing the primary capsule with the solution obtained in 6) to produce a double capsule dispersion in which the primary capsule is bound to the second binder; and 8) spray-drying the double capsule dispersion to product a double capsule from which the second solvent is removed.

Charcoal-containing double capsule and method for manufacturing same

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.
