Abstract
A laminate comprising a thermoplastic resin film having thereon a coating layer containing (A) 100 parts by weight of an antistatic agent comprising a water-soluble quaternary nitrogen-containing polymer, (B) 10 to 600 parts by weight of a polyethyleneimine polymer selected from the group consisting of polyethyleneimine, alkyl-modified polyethyleneimine, poly(ethyleneimine-urea), and an ethyleneimine adduct of polyaminepolyamide, and (C) 25 to 1000 parts by weight of a polyalkylene ether polymer selected from the group consisting of polyethylene glycol, polypropylene glycol, an ethylene oxide-propylene oxide copolymer, and derivatives thereof, each having a molecular weight of 200 to 20,000. The laminate has excellent antistatic properties and offset printability.
