Printing medium, production process thereof and image-forming process

摘要

Disclosed herein is a printing medium provided on a base material with a porous ink-receiving layer which comprises, as principal components, an alumina hydrate having a boehmite structure and a binder, wherein when measuring with an ink containing 0.1 % by weight of a surfactant, the time required to absorb 30 ng of an ink is 400 milliseconds or shorter, the dye-adsorbing capacity falls within a range of from 900 to 2,000 mg/m<2>, and the index of dye-adsorbing rate falls within a range of from 0.0 to 5.0.
