Disclosed is a reusable multilayered xerographic transparency article comprising a transparent base sheet, having attached thereto one or both faces of the base sheet, with a suitable attachment means, such as an adhesive or an unobtrusive binding fastener, on at least one side or edge, in preferably the process direction, a plurality of thinner transparent sheets or top sheets. The thinner sheets and attachment means are selected to be environmentally and economically advantageous to enable the reuse of the transparency article by removing, for example in the case of an adhesive attachment, the outermost thinner transparent top sheet. A suitable transparent base sheet is, for example, commercially available clear polyethylene terephthalate film of about 4 mil thickness. Suitable pressure sensitive adhesives are, for example, known pressure sensitive polyacrylates. Suitable top sheet material is engineering drafting film or MYLARD, of about 0.5 to about 3 mil thickness for each layer. The number of top sheets can be from 1 to about any number, for example 10, such that the transparency article is capable of being xerographically, or otherwise, imaged and projected with reasonable print and image fidelity. When some or all the top sheets have been removed through reuse, the base sheet may be used as a terminal transparency support, or the base sheet may be optionally retrofitted with a fresh load of top sheets ad infinitum.
