Abstract
A form comprises a cellulosic sheet having a perforation defining a first portion and a second portion. The first portion may define either a card or alternatively a label, and is impregnated with a waterproofing polymerizable composition. The first portion is preferably resistant to water, and is receptive to inks. As such, user variable indicia may be applied anywhere on the sheet including the first portion. For applications requiring a label, an adhesive and liner ply may be applied to the back of the sheet. The liner ply includes a release coating in register with the first portion defining the label, such that, upon removing the label from the sheet, a substantial portion of the adhesive remains with the label.
