Abstract
A method of making an index tab label assembly using a label having a coating that facilitates printing on the label. Each label is made out of a polyester film having a pressure-sensitive adhesive attached to one side of the film and a coating comprising aluminum oxide, resin chips, methyl ethyl ketone, and toluene, applied to the other side of the sheet. The coating provides good anchorage for toner, abrasive resistance for writing, and electrostatic properties that facilitate printing when using laser or xerographic equipment. The labels are die cut from a thin sheet of film attached to a backing sheet by the pressure sensitive adhesive. Top, bottom and vertical strips of the thin sheet of film remain on the backing sheet after die cutting to facilitate passing the labels and backing sheet through a printing device, by preventing jamming as the assembly passes through the device. Indicia are printed on the labels by sending the labels and backing sheet through the printing device. One of the printed labels is then removed from the backing sheet and attached by the pressure sensitive adhesive directly to a tab of a divider or file to make an index tab, or to a tab reinforcer atta…
