Abstract:
A polyester film composite material comprising a biaxially oriented polyester film having a thickness of at least 50 &mgr;m but not more than 200 &mgr;m and an easy-adhesion coating applied onto one or each surface thereof, and having a haze value of less than 2% and a total light transmissivity of at least 90%,wherein the biaxially oriented polyester film is a single-layered polyester film or a laminated polyester film, and a polyester constituting a single layer or at least an outer film of a laminated film in said biaxially oriented polyester film contains at least 0.001% by weight but not more than 0.1% by weight of porous silica particles and/or plate-like aluminum silicate particles having an average particle diameter of at least 0.1 &mgr;m but not greater than 3 &mgr;m, and said easy-adhesion coating has a composition composed, substantially of (A) a water-base polyester resin having a glass transition point of 40 to 80Â° C., (B) an acrylic resin having a glass transition point of 25 to 75Â° C. and (C) acrylic crosslinked polymer particles.
