  1-3 which show the fragrance | flavor containing microcapsule carrier of a present Example, S0 is a microcapsule mixed layer, and microcapsule mixed layer S0 consists of a mixture of the fragrance | flavor containing microcapsule 1 and the adhesive agent 2. FIG. Examples of the fragrance contained in the fragrance-containing microcapsule 1 include various essential oils and solid fragrances. The microcapsule mixed layer S0 is bonded to an adherend A such as cloth or paper. Further, S1 to Sn are adhesive layers made of the adhesive 3, and the adhesive layers S1 to Sn are formed on the microcapsule mixed layer S0. Since the release of the fragrance from the fragrance-containing microcapsule 1 is suppressed by forming the adhesive layers S1 to Sn on the microcapsule mixed layer S0, the fragrance is gradually released without changing the internal structure of the fragrance-containing microcapsule 1. The period can be greatly expanded. Further, the sustained release period of the fragrance can be controlled by adjusting the number of the adhesive layers S1 to Sn, that is, the thickness of the adhesive layer, and the sustained release period of the fragrance is, for example, 1 month to 1 Can be controlled between years.

  The adhesive 2 used for the microcapsule mixed layer S0 and the adhesive 3 used for the adhesive layers S1 to Sn are preferably polymer adhesives having flexibility after drying, but are not limited to specific types. When a polymer-based adhesive having flexibility after drying is used as the adhesives 2 and 3, the adhesive becomes flexible as shown in FIG. Release can be facilitated. FIG. 2 shows a case where the adhesive layer S1 is one layer.

  Further, as the adhesives 2 and 3, a polymer adhesive that can be peeled off and re-adhered can be used. When a peelable and re-adhesive polymer adhesive is used, as shown in FIG. 3, the perfume-containing microcapsule carrier is peeled off from the adherend A such as cloth, paper or board and re-adhered. Can do. FIG. 3 shows a case where the adhesive layer S1 is one layer. As such a polymer-based adhesive, for example, an acrylic rubber adhesive, an adhesive modified with an acrylic acid ester monomer to have re-adhesion after peeling, and the like can be used.

  The fragrance | flavor containing microcapsule carrier of a present Example is shown in FIG. In this embodiment, the layered compound 4 is dispersed and contained in the two adhesive layers S1 to S2. As the layered compound 4, mica (mica) or clay containing mica can be used.

  A polyurea containing each of eucalyptus essential oil, grapefruit essential oil, and jasmine essential oil is sprayed onto a cotton cloth (10 cm × 10 cm) with an acrylic rubber adhesive (spray glue manufactured by Sumitomo 3M Limited) having re-adhesive properties after peeling. A certain amount of microcapsules and melamine resin microcapsules containing fern essential oil were applied to form a microcapsule mixed layer S0, which was used as a sample. Moreover, the acrylic rubber adhesive which has the re-adhesive property after peeling from microcapsule mixed layer S0 is sprayed, adhesive layer S1 (1 layer), adhesive layers S1-S2 (2 layers), adhesive layer Samples were formed by forming S1 to S3 (three layers) and adhesive layers S1 to S4 (four layers), respectively. And the sustained release time of the essential oil component from each sample was measured by gas chromatography.

  For each of the above samples, between the microcapsule mixed layer S0 and the adhesive layer S1, between the adhesive layer S1 and the adhesive layer S2, between the adhesive layer S2 and the adhesive layer S3, and between the adhesive layer S3 and Samples were prepared by adding mica as the layered compound 4 between the adhesive layers S4, and the sustained release time of the essential oil component from each sample was measured.

  FIG. 5 shows the relationship between the thickness of the adhesive layer of the fragrance-containing microcapsule carrier and the sustained release time. In both the cases where the layered compound 4 was added to the adhesive layers S1 to S4 and the case where the layered compound 4 was not added, the sustained release time was greatly expanded as the adhesive layer became thicker (the number of adhesive layers increased). . In addition, when the layered compound 4 was added to the adhesive layers S1 to S4, the sustained release period was increased by about 50% compared to the case where the layered compound 4 was not added.

Samples were prepared by supporting microcapsules containing each of lavender essential oil, grapefruit essential oil, eucalyptus essential oil, and fern essential oil on a cloth (5 cm × 5 cm). Three types of samples were prepared, one having a microcapsule loading of 1 g / cm ² , 5 g / cm ^2, and 10 g / cm ² . And the sensory evaluation test was implemented about each sample. In addition, a sensory evaluation test was performed after each sample was rubbed by hand and part of the microcapsules was destroyed.

  The result is shown in FIG. Grapefruit essential oil, eucalyptus essential oil, and fern essential oil showed a tranquilizing effect (a positive evaluation value) due to the components released from the microcapsules, and the tranquilizing effect was maintained even after the sample was massaged. On the other hand, lavender essential oil showed a mental stabilizing effect, but when the sample was swallowed, the amount of essential oil released increased and shifted to a mental enhancement effect (negative evaluation value).
