ERASABLE DIAZOTYPE MATERIAL AND METHOD THEREFOR

摘要

Written, typed, penciled, printed and other markings on paper and foils can be erased easily by mechanical means by utilizing an improved interlayer between the surface of the base material and the markings. The interlayer includes a copolymer resin of acrylate-vinyl chloride. The provision of such an interlayer is particularly useful for diazotype intermediate prints.
