Abstract

PURPOSE:To manufacture the capsule having a high mechanical strength, by irradiating light on emulsified material and carrying out light bridge formation after adding water solution of core material, such as enzyme, to organic solvent of hydrophilic high molecular compound introduced hydrophobic light sensitive radical and emulsifying it and next, carrying out the secondary emulsification of emulsified solution in the water solution. CONSTITUTION:Light bridge forming high molecular compound obtained by introducing hydrophobic light sensitive radical, such as cinnamoyl radical etc., to hydrophilic high molecular compound, such as PVA etc., is dissolved in organic solvent. Next, emulsification is carried out by adding water solution of core material, such as enzyme, hormone or agricultural or medical products, to the above solution and moreover, the secondary emulsification of the emulsified solution is carried out in the water solution. Then, light is irradiated on the above emulsified solution and bridge formation of the high molecular compound is carried out through the light sensitive radical. Hereby, microcapsule including so-called core material and composed of the high molecular compound carried out light bridge formation of outer crust, is obtained.
