PURPOSE:To obtain a recording medium capable of providing recorded images having both image density and indoor discoloration resistance by forming a layer containing spherical basic magnesium carbonate on a substrate. CONSTITUTION:The objective recording medium prepared by forming a layer containing spherical basic magnesium carbonate (preferably having 1-12mum average particle diameter and 10-170m<2>/g specific surface area measured by the BET method) on a support. Furthermore, the ink permeation rate into the recording medium is preferably 10-60nl/mm<2>.sec. |
