[0132] Hereinafter, the present invention will be explained in more detail through examples, but the present invention is not limited to them at all. The parts and% in the following examples and comparative examples represent parts by mass and% by mass, unless otherwise specified.

[0133] "Making of attached materials"

[0134] 1. Adhesive

[0135] As the acrylic adhesive, acrylic adhesive 1 and acrylic adhesive 2 were used. Acrylic adhesive 1 is made by adding 0.3 parts by mass of Coronate to 100 parts by mass of an alkyl acrylate copolymer containing isononyl acrylate / 2-methoxyethyl acrylate / acrylic acid (mass ratio 68 / 30 / 2) (Registered trademark) HL (manufactured by Nippon Polyurethane Industry Co., Ltd.) as an acrylic adhesive obtained as a crosslinking agent. Acrylic adhesive 2 is made by adding 0.03 parts by mass of TETRAD-X (registered trademark) (Mitsubishi Gas Chemical Corporation) to 100 parts by mass of an alkyl acrylate copolymer containing isononyl acrylate / acrylic a...

[0174] The ethyl acetate solution of the acrylic adhesive (the total solid content is about 40% by mass) is dried to a thickness of 40g / m 2 The method is applied to one side of the release body, and then dried to form an adhesive layer, and each support body is laminated to produce an attached material. The acrylic adhesives and supports used are shown in Table 3, respectively. The characteristics of the obtained adhesive material were measured using the method described later, and are shown in Tables 4-8. It should be noted that "-" in Table 6 indicates that it has not been implemented.

Abstract

The present invention addresses the problem of providing an adhesive skin patch material for covering a wound or protecting a postoperative wound, particularly an adhesive skin patch material for healing a wound, for treating a scar or for preventing the formation of cicatrices or keloid, which can prevent the stretching of skin, has excellent followability to the movement of skin and can be adhered for a long period. The present invention also addresses the problem of providing a support for adhesive skin patch materials, which is suitable for the above-mentioned adhesive skin patch material.The present invention is an adhesive skin patch material for covering a wound or for protecting a postoperative wound, said adhesive skin patch material comprising a support and an adhesive agent layer provided on one surface of the support, wherein the 1% tensile load and the 10% tensile load of the adhesive skin patch material in each of the longitudinal direction and the lateral direction are13 N / 25 mm or less and 18 to 95 N / 25 mm inclusive, respectively.

Description

Technical field [0001] The present invention relates to a patch material, especially a patch material for wound covering or postoperative wound protection, and further to a patch for healing wounds, for treating scars, or for preventing the formation of scars / keloids (ケロイド), etc. Adhesive material and support for the adhering material used therein. Background technique [0002] Injuries and skin wounds caused by surgery are usually healed in about two weeks, after which changes continue for about half a year. Generally, the scar becomes hard and red after about 1 month, and then it takes several months to gradually soften, and the color gradually becomes the same as the surrounding skin. However, if the normal process of wound healing is hindered for some reason, sometimes the wound will not heal and present a chronic or abnormal healing method. One of the cures for abnormalities is called scars and keloids. The mechanism of scars and keloids is not clear, and it is also point...
