Claim 11:
12. An organic-inorganic hybrid microcapsule, comprising a dispersed phase which is a core, and a hybrid capsule outer wall formed at an interface of the dispersed phase and surrounding outside of the dispersed phase;
wherein the hybrid capsule outer wall is an inorganic nanoparticles-polymer resin composite containing i) at least one polymer selected from the group consisting of polyamides polyurethane, polyurea, polyester and poly(β-amino ester), and ii) inorganic nanoparticles,
wherein the polymer precursor 2 is at least one selected from the group consisting of a compound containing two or more acid chloride structures represented by the Chemical Formula 3, and a compound containing two or more chloroformate structures represented by the following Chemical Formula 5:, (in Chemical Formula 3, each R3 may independently comprise C1 to C50 alkylene, a C3 to C60 cyclic hydrocarbon group, or C1 to C50 alkylene and a C3 to C60 cyclic hydrocarbon group having or not having at least one acid chloride (-COCl) or at least one heteroatom), (in Chemical Formula 5, each R5 may independently comprise C1 to C50 alkylene, a C3 to C60 cyclic hydrocarbon group or C1 to C50 alkylene and a C3 to C60 cyclic hydrocarbon group having or not having at least one chloroformate (-OCOCl) or at least one heteroatom).
