Antistatic layer containing hydrophobic polymer particles and conductive polymer

Claim 1

In an antistatic layer for a plastic film; said antistatic layer consisting essentially of a water-soluble conductive polymer and particles of a hydrophobic polymer and said antistatic layer having been cured by using a hardener, the improvement wherein said hydrophobic polymer is a polymer obtained by copolymerization at least one of a monomer having an amide group and a monomer having a polyalkylene oxide chain with a monomer selected from the group consisting of styrene, styrene derivative, alkyl acrylates, alkyl methacrylates, olefin derivatives, halogenated ethylene derivatives, acrylamide derivatives, methacrylamide derivatives, vinyl ester derivatives and acrylonitrile, said monomer having an amide group is represented by the formula (I): ##STR20## wherein R represents a hydrogen atom or a lower alkyl group having 1 to 4 carbon atoms; L represents a divalent group; a represents 0 or 1; and R 1 and R 2 each represent a hydrogen atom or a lower alkyl group having 1 to 6 carbon atoms; said monomer having a polyalkylene oxide chain is represented by the formula (M): ##STR21## wherein said R represents a hydrogen atom, a halogen atom, a lower alkyl group or --CH 2 --L--X; L represents a divalent group selected from a group of --COO-- and ##STR22## and an arylene group having 6 to 12 carbon atoms; R 1 represents a hydrogen atom, an aryl group or a lower alkyl group; X represents --(R 2 --O) n --R 3 where R 2 is at least one selected from --CH 2 CH2--, ##STR23## R 3 represents a hydrogen atom, a lower alkyl group, an alkylsulfonic acid group or its salt, or an alkylcarboxylic acid group or its salt; and n is an integer of not less than 2 and not more than 70: wherein said water-soluble conductive polymer has at least one conductive group selected from the group consisting of a sulfonic acid group, a sulfuric acid ester group, a tertiary ammonium salt, a quaternary ammonium salt and a carboxyl group; wherein said hardener is an epoxy compound; and wherein a ratio of said water-soluble conductive polymer, said particles of hydrophobic polymer and said hardener is 40 to 95 weight %: 5 to 50 weight %: 1 to 45 weight %.
