Abstract:
1. A laminate comprising: a support; and an antistatic layer, wherein the antistatic layer is provided on the support and comprises 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, wherein the binder component (B) comprises a binder component (B1) having a number average molecular weight of greater than or equal to 1,500 and less than 500,000 and selected from the group consisting of styrene resins, (meth)acrylic resins, vinyl ester resins, vinyl ether resins, halogen-containing resins, alicyclic olefin resins, polycarbonate resins, polyester resins, polyamide resins, cellulose derivatives, silicone resins, and rubbers or elastomers, and wherein the binder component (B) comprises a binder component (B2) having a molecular weight of greater than or equal to 200 and less than 1,500 and comprising a polyfunctional monomer having three or more (meth)acryloyl groups in one molecule.
