摘要 |
A microcapsule includes a shape memory resin shell wall formed with fissures that do not completely pass through the shell wall, and a dye encapsulated in the shell wall. The shell wall exhibits a temperature/pressure characteristic such that the fissures open, when the shell wall is squashed and compacted under a predetermined pressure at a predetermined temperature, whereby a seepage of the dye frog the squashed and compacted shell wall through the opened fissures is adjustable.
