Problems solved by technology

Therefore, a positive antibacterial effect (antibacterial activity) of 4-isopropyl cycloheptadienolone is not expected
[0009] In addition, regarding the production of adhesive sheets containing volatile antibacterial agents such as 4-isopropyl cycloheptadienol, 4-isopropyl cycloheptadienol has caused many troubles in handling because 4-isopropyl cycloheptadienol Cycloheptadienol is readily volatile during the heating process
Therefore, the current status is that it has not been tested to create an antimicrobial environment by effectively using its easily volatile properties, allowing volatile antimicrobial agents to exert high activity not only at the adhesion site but even in the space near the adhesion site. Antibacterial effect and broad antibacterial spectrum

Abstract

An antimicrobial adhesive sheet containing an antimicrobial agent which exerts the antimicrobial activity not only on an attached site but also in the space in the vicinity of the attached site, and an antimicrobial method using the sheet. The antimicrobial adhesive sheet has a moisture permeability of at least 1,000 g / m 2 €¢ 24 hrs as the whole sheet, where a non-aqueous adhesive layer containing a vaporizable antimicrobial agent is formed on one side of the support. As the support, non-woven fabric and porous plastic sheet are preferable. In case of non-porous plastic sheet, polyurethane resins and polyamide resins are preferably used. As the vaporizable antimicrobial agent, hinokitiol is preferable and inclusion compounds thereof may also be used. As the adhesive, an acrylic adhesive prepared by polymerizing a (meth)acrylic acid alkyl ester as the main component is preferably used.

Description

technical field [0001] The invention relates to an antibacterial adhesive sheet and an antibacterial method using the antibacterial adhesive sheet. More particularly, the present invention relates to an antibacterial adhesive sheet exerting an antibacterial effect not only on the surface of its adhered site but also in the space near its adhered site by using a specific carrier. The invention also relates to an antibacterial method. Background technique [0002] As medical tablets to be adhered to the skin surface, many types have been developed so far including, for example, adhesive garments, wrap-around adhesive tapes, first aid adhesive tapes, adhesive bandages, muffins containing medicaments for topical use, etc. Cataplasm plasters, transdermal strip preparations containing agents for systemic use. [0003] When these medical adhesive sheets are attached to injured skin to treat the skin, the injured part may sometimes be infected by bacteria present on the skin surfa...
