By causing triboelectric charging, it can be electrostatically adsorbed on a solid surface such as paper or glass.
  • the inventor of the present invention has conducted intensive studies on the reason why the electrostatic attraction force of the backing film to which the display sheet is adhered is reduced with the passage of time, and as a result, the plasticizer contained in the adhesive layer and Z or the softening agent are reduced.

Abstract

Matériau support d'affichage composé d'un film plastique d'attraction électrostatique et d'une feuille d'affichage ayant une couche adhésive exempte de plastifiant et d'assouplissant, d'une couche de résine autocollante ou d'une couche de mousse de résine autocollante, sur sa face arrière. Le matériau ne subit pas une très forte diminution de la force d'attraction électrostatique du film plastique même lorsque la feuille et le film sont liés par laminage puis laissés ainsi pendant longtemps. Ledit matériau peut être utilisé comme support publicitaire éducatif sur lequel on applique des lettres ou des dessins utiles, sur la surface de la feuille d'affichage.
