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.

First claim

2. The polymerizable composition according to claim 1 , wherein X 2 and X 3 in Formula 3 are each independently an ester bond or an arylene group, and R 12 is an alkylene group having 2 to 12 carbon atoms.

3. The polymerizable composition according to claim 1 , further comprising a compound represented by Formula 4 below:

wherein, R 16 is hydrogen or an alkyl group, X 4 is an ester bond, an amide bond, a sulfonamide bond, a phosphoramide bond or an arylene group, Y 4 is an alkylene group, R 17 , R 18 and R 19 are each independently an alkyl group, an alkylalkanoate group or an aryl group, and Z − is an anion.

4. The polymerizable composition according to claim 3 , wherein X 4 in Formula 4 is an ester bond or an arylene group, and R 17 , R 18 and R 19 are each independently an alkyl group having 8 to 20 carbon atoms.

5. The polymerizable composition according to claim 3 , wherein the polymerizable composition comprises the compound represented by Formula 4 in an amount of 1 part by weight to 30 parts by weight per 100 parts by weight of the polymerizable monomer.

6. The polymerizable composition according to claim 1 , wherein the polymerizable composition comprises the polymerizable monomer in an amount of 15 wt% to 85 wt% relative to a total weight of the polymerizable composition.

7. The polymerizable composition according to claim 1 , wherein the polymerizable composition comprises the compound represented by Formula 3 in an amount of 0.1 parts by weight to 15 parts by weight per 100 parts by weight of the polymerizable monomer.

8. The polymerizable composition according to claim 1 , further comprising a fragrance.

9. The polymerizable composition according to claim 8 , wherein the polymerizable composition comprises the fragrance in an amount of 15 parts by weight to 75 parts by weight per 100 parts by weight of the polymerizable monomer.

10. Polymer capsules comprising a shell material containing a unit of a compound represented by Formula 1 below and a unit of a polymerizable monomer:

wherein, R 1 is hydrogen or an alkyl group, X is an ester bond, an amide bond, a sulfonamide bond, a phosphoramide bond or an arylene group, Y is an alkylene group, R 2 and R 4 are each independently hydrogen, an alkyl group, an alkylalkanoate group or an aryl group, R 3 is an alkyl group, an alkylalkanoate group, an aryl group or a functional group represented by Formula 2 below, and Z 31 is an anion:

wherein, * is a site bonded with N+ in Formula 1, R 6 is an alkylene group or an arylene group, R 5 and R 7 are each independently an alkyl group, an alkylalkanoate group or an aryl group, Y 1 is an alkylene group, X 1 is an ester bond, an amide bond, a sulfonamide bond, a phosphoramide bond or an arylene group, R 8 is hydrogen or an alkyl group, and Z − is an anion.

11. The polymer capsules according to claim 10 , wherein cations derived from the compound represented by Formula 1 are present on the surfaces.

12. The polymer capsules according to claim 10 , further comprising a fragrance supported therein.

13. A fabric softener composition comprising the polymer capsules of claim 10 .
