Abstract
An inkable sheet comprises a substrate and ink-absorbent layer, the surface of which exhibits an internal contact angle of at least 120.degree.. A modifying treatment provides a microporous surface zone of reduced apparent hydrophilicity which accepts a high loading of an aqueous-based ink. Ink patterns of high resolution are thereby achievable.
