To prepare a microcapsule containing a coloring matter, which requires neither a polymerization reaction nor pH adjustment and which can realize the raw material recovery and the repolymerization, to provide a process for producing it, and a method for recording by using it.

The microcapsule containing a coloring matter is formed by the self-integration of a polymer. The process for producing it involves a step of subjecting a polymer to self-integration. The recording method is characterized in that the microcapsule containing a coloring matter is used. The polymer used preferably comprises a rod-coil block copolymer consisting of rod units whose main chain comprises an aromatic compound and coil units whose main chain comprises a saturated aliphatic chain.
