Patent ID: 8349451

Claim:
Capsular fine particles consisting of an encapsulated material selected from the group consisting of a gas, a liquid, a solid inorganic material and solid organic material, and an olefinic polymer wherein the olefinic polymer is a homopolymer or copolymer of at least one or more monomers selected from the group consisting of linear or branched α-olefins having 2 to 6 carbon atoms, wherein the olefinic polymer is a homopolymer of a single olefinic monomer selected from the group consisting of ethylene, propylene, 1-butene, 3-methyl-1-butene and 4-methyl-1-pentene; or a copolymer containing 0.01 to 10% by mole of another olefinic monomer selected from the group consisting of ethylene, propylene, 1-butene, 3-methyl-1-butene, and 4-methyl-1-pentene.
