摘要 |
<p>The invention provides a recording medium providing an image storage property over a prolonged period and satisfactory recording properties at the same time, and a producing method for securely realizing such characteristics. In incorporating a colorant deterioration preventing agent in an ink-receiving layer, the colorant deterioration preventing agent is dissolved in a solvent and is applied on the ink-receiving layer thereby forming a high concentration region containing the colorant deterioration preventing agent at a high concentration and a low concentration region containing the colorant deterioration preventing agent at a low concentration, with the high concentration region positioned closer to the recording surface.</p> |
