Beschreibung
Zusammenfassung:	Disclosed are heat storage microcapsules encapsulating a water-soluble heat storage material stably and certainly, heat storage microcapsules with high durability which prevent phase separation of an inorganic salt hydrate latent heat storage material, heat storage microcapsules which prevent supercooling of a latent heat storage material to exhibit stable heat history and a manufacturing method thereof. The heat storage microcapsules comprise a core covered with a shell, wherein the core contains (a) at least one water-soluble latent heat storage material selected from a salt hydrate and a sugar alcohol and (b) a polymer derived from a water-soluble monomer mixture of a water-soluble monofunctional monomer and a water-soluble multifunctional monomer, and the shell is composed of a hydrophobic resin.
