  • Patent number: 11214759
    Abstract: A polymerizable composition, polymer capsules and a fabric softener composition are provided. The fabric softener composition includes polymer capsules in which cationic groups are introduced on the surfaces thereof, so that early release of a fragrance can be suppressed and aromas can be generated depending on rupture of a shell material of the polymer capsules by light friction at certain times. In addition, the polymer capsules have high adhesion to fibers and are not attached to fibers during washing to minimize the discharged fragrance, so that sufficient aromas can be provided even if a small amount of fragrance is used.
