Abstract
An object of the present invention is to provide: a plasma treatment detection indicator comprising a color-changing layer that exhibits improved heat resistance so that the layer does not change color even when overheated at up to about 170° C. as a result of a plasma-generating gas not being supplied or being insufficient due to a defect in a plasma treatment device; and an ink composition for detecting plasma treatment, the composition being for forming the color-changing layer. The ink composition for detecting plasma treatment includes a colorant and a binder resin containing a phenol resin, and the plasma treatment detection indicator uses the ink composition.
