The polymer having a quaternary ammonium salt group is, for example, a copolymer obtained by polymerizing a vinyl monomer (c1) having a quaternary ammonium salt structure (herein, also referred to as a "c 1 component"), a vinyl monomer (c2) having a weight average molecular weight of 4,000 to 10,000 (herein, also referred to as a "c 2 component") obtained by ring-opening polymerization of a hydroxyl group-containing vinyl monomer and a lactone, a vinyl monomer (c3) having a branched alkyl ester group having 3 to 5 carbon atoms and having no alicyclic structure (herein, also referred to as a "c 3 component"), and, if necessary, a vinyl monomer (c4) (herein, also referred to as a "c 4 component") other than these at a predetermined mass ratio.

(c2) The component (b) is a component obtained by ring-opening polyaddition reaction of a hydroxyl group-containing vinyl monomer and a lactone, and can be used without particular limitation. In addition, when another long-chain monomer (e.g., a vinyl monomer having an alkylene oxide structure with an alkyl terminal in the molecule) is used instead of the component (C2), the antistatic ability of the component (C) tends to be insufficient. Examples of the hydroxyl group-containing vinyl monomers include hydroxyl group-containing (meth) acrylates and hydroxyl group-containing vinyl monomers. Examples of the hydroxyl group-containing (meth) acrylate include: hydroxyethyl (meth) acrylate, hydroxypropyl (meth) acrylate, hydroxybutyl (meth) acrylate, hydroxyethyl (meth) acryloylamide, and the like.

A: minimum diameter of 5mm
B: minimum diameter of 6mm or more
< evaluation of Properties (5): abrasion resistance test
A rubber (product name "military rubber stick", manufactured by minoen (Minoan)) was used as a head of a friction tester, pressed vertically from above to the surface of the resin layer of the laminate with a load of 1000g, rubbed reciprocally 1000 times at a stroke length of 2.0cm and a rubbing speed of 60rpm, and then the attached rubber was removed, and then a water contact angle was measured and evaluated according to the following criteria. The water contact angle was measured as follows. The water contact angle at 23 ℃ and 50% relative humidity of the resin layer of the laminate after rubbing with a rubber was measured by a liquid Drop method in which 2.0. mu.L of a water Drop was dropped and measured 1000ms after dropping the water Drop by a theta/2 method using a contact angle measuring apparatus (product name "Drop Master DM-300", manufactured by Kyowa Kagaku Kogyo Co., Ltd.).
AAA: the contact angle of water exceeds 106 °
AA: the contact angle of water is more than 104 DEG and less than 106 DEG
A: the contact angle of water is more than 103 DEG and not more than 104 DEG
B: the contact angle of water is less than 103 DEG
