The invention relates to a microcapsule comprising an inorganic antimicrobial agent coated with a hydrophilic polymer. The hydrophilic polymer is able to absorb sufficient water as to enable the action of the encapsulated antimicrobial agent. These microcapsules are useful to impart antimicrobial activity and can be used in polymer compositions, sprays and coatings. A method of preparing the microcapsule by treatment of the antimicrobial agent with a solution of the hydrophilic polymer is provided. Another embodiment of the invention is a method of preparing the microcapsule by coating of the antimicrobial agent with a polymer precursor followed by treatment with a reactive ingredient. Another embodiment of the invention is a method of preparing the microcapsule by melt compounding the antimicrobial agent with the hydrophilic polymer followed by grinding to the desired particle size. Polymer compositions comprising the microcapsules and a matrix polymer are also provided. Another embodiment of the invention is an article prepared from the polymer compositions comprising the microcapsules and a matrix polymer.

PROBLEM TO BE SOLVED: To provide a polylactic acid resin composition from which a pouched film having practically-satisfactory flexibility and strength can be formed and which can be solubilized satisfactorily in an anaerobic atmosphere. SOLUTION: The polylactic acid resin composition includes: polylactic acid; a plasticizer for the polylactic acid (for example, an ester-based plasticizer such as aliphatic dicarboxylate) and/or a soft resin (for example, polyalkylene alkanoate such as polyalkylene succinate and poly(alkylene alkanoate/allylate)); and a polymer having a thickening function. It does not matter if the polymer having the thickening function is typically a polymer having a reactive group (particularly, an epoxy group) to be reacted with a hydroxy group and/or a carboxy group.

PROBLEM TO BE SOLVED: To obtain an antimicrobial polymer particle having improved affinity for resins and coating film properties and excellent antimicrobial properties by using an antimicrobial metal component. SOLUTION: This antimicrobial polymer particle is obtained by supporting an antimicrobial metal component capable of forming coordinate bond to a functional group (silver component or the like) on a hydrophilic polymer particle (0.1 nm to 100 μm average particle diameter) consisting of hydrophilic polymer gel having a crosslinked structure comprising hydrophilic units each containing a nitrogen atom, units each having a functional group containing at least one atom selected from oxygen nitrogen and sulfur and crosslinked units. Wherein, the functional group includes a carboxyl group, an amino group, an imino group, a mercapto group or the like. The supported amount of the antimicrobial metal component is about 0.01-70 wt.% in terms of the metal based on the total amount. The antimicrobial particle has good affinity for resins and is useful as an antimicrobial resin composition (a coating resin composition or the like). COPYRIGHT: (C)1999,JPO
