INK COMPOSITION FOR PLASMA TREATMENT DETECTION, AND PLASMA TREATMENT DETECTION INDICATOR

摘要

(Problem) To provide a plasma treatment detection indicator which, by controlling the color changing speed, makes it possible to verify the completion of plasma treatment by the color change of a color changing layer without regard to the magnitude of the plasma strength or the type of low-pressure plasma or atmospheric plasma, and to provide an ink composition for plasma treatment detection in order to form said color changing layer. (Solution) This ink composition for plasma treatment detection is characterized by containing an organic dye, and at least one item selected from a group consisting of a photopolymerization initiator, silica and hydrophobic alumina.
