ABSTRACT:
This invention relates to an electrosensitive marking blank having a blushed conductive layer and a pigment containing blushed masking layer. The instant electrosensitive element has particular utility in that a relatively thin masking layer in combination with a blushed conductive layer results in a blank having improved whiteness and contrast characteristics.
