Abstract

In this study, dye-encapsulated microcapsules were produced by emulsion polymerization using styrene monomer. The study showed that the average size of microcapsules were $2{\sim}5{\mu}m$ in normal distribution. These microcapsules induced pale yellow(A12) and reddish yellow(B24) color by thermochromic fluoran yellow(dye A) and red(dye B). These microcapsules were changed to dark yellow(A12) and scarlet(B24) color depending on temperature change. The weight of microcapsules decreased by 7% to 11% during the heating ranges from $320^{\circ}C$ to $350^{\circ}C$ implying that the styrene microcapsules had thermal stability upto $300^{\circ}C$.
