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.
