Permanent xerographic toner-receptive index divider

A permanent xerographic toner-receptive index sheet assembly, comprising:

• an index sheet;
• a reinforced index tab extending from said sheet, said index tab being formed of plastic film having a thickness of from about 0.5 mils to about 5 mils and adhesively bonded to said index sheet;
• said index tab having a polymer coating directly applied thereto, said coating having a glass transition temperature at which the polymer becomes less hard and brittle below the effective xerographic copier toner fusing temperature, but retaining its integrity at temperatures at least as high as 200.degree. F.;
• said reinforced index tab with polymer coating applied thereto being of substantially the same thickness as said index sheet, whereby the coating forms a bond with xerographic toner applied thereto;
• and
• said coating with toner bonded thereto having high abrasion resistance capable of withstanding 50 double passes of an ASTM Gardner Scrape Adhesion Tester with a 250 gram weight applied thereto, without significantly impairing the toner bound to the reinforced index tab.
