<p>PROBLEM TO BE SOLVED: To provide an ETC system which can automatically collect tolls with high reliability by coating at least more than one surface of a constitution member with electromagnetic wave absorptive paint other than epoxy resin, and then forming a thin and lightweight electromagnetic-wave absorptive film which is excellent in weatherability in common to all bases and imparting stable and excellent electromagnetic wave absorption characteristics. SOLUTION: This ETC system comprises system constitution members such as an antenna, a display unit, a toll gate structure, electronic equipment, and an auxiliary member and sends and receives signal to and from passing vehicles to automatically collect tolls and is characterized by that at least one system constitution member has the electromagnetic wave absorptive coating layer formed by dispersing magnetic powder by using as a matrix a resin composition made of acrylate copolymer modified resin.</p> |
