Abstract:
A laminate having: a support; and an antistatic layer, wherein the antistatic layer is provided on the support and is made with a composition comprising at least (A) an electrically conductive polymer, and (B) a binder component, the antistatic layer has regions having local concentration of the electrically conductive polymer (A) of 1.5 times or more higher than the average value of the concentration of the electrically conductive polymer (A) in the antistatic layer and the regions are in contact with each other to form a three-dimensional connection structure in the antistatic layer, and a common logarithmic value of the surface resistivity of which unit is Ω/sq of the antistatic layer is 3.0 or more and 13.0 or less.
