Absorption microspectroscopy has been conducted to study chemical properties of single melamine-resin microcapsules containing a zinc tetraphenylporphine (ZnTPP)/toluene solution. Although absorbance of ZnTPP in the capsule increased with increasing the capsule diameter, its tendency was much smaller than that expected from a homogeneous distribution of ZnTPP in the inner toluene solution. The results were discussed in terms of a distribution of ZnTPP in both the melamine-resin and toluene phases.
