Abstract
An imageable article comprising a photoresist layer on a substantially radiation absorbing layer of metal having a microstructured surface characterized by a plurality of randomly positioned discrete protuberances of varying heights and shapes, which protuberances have a height of not less than 20 nanometers nor more than 1500 nanometers, and the bases of which contact the bases of substantially all adjacent protuberances is disclosed. The imageable article is particularly useful in the field of graphic arts.
