Ink for surgical marker
A precise, quick mark showing a surgical operation site is allowed to put on a marking target irrespective of the skin or a surgical drape attached onto the skin in surgical operation. An ink for a surgical marker is made of isopropyl alcohol as a solvent, polyvinyl pyrrolidone involved in film formation, and methylrosanilinium chloride as a pigment, and, in particular, the content of the polyvinyl pyrrolidone is set to be greater than or equal to 2% but smaller than or equal to 12%. The composition described above allows the ink to be smoothly discharged and a film containing the pigment to be quickly formed and adhered as the ink dries. A mark can therefore be put in a precise, quick manner irrespective of a marking target, the skin or a surgical drape attached onto the skin.
