Abstract
Abstract A light-transmissive recording medium is provided which has an ink receiving layer formed mainly of a water-soluble polymer and a crosslinking agent on a light-transmissive substrate, wherein the polymer constituting said ink receiving layer has a crosslinking degree within the range of from the crosslinking degree satisfying the water resistance of the ink receiving layer in JIS K 5400 to the crosslinking degree giving the ink receiving capacity of 0.2 mu l/cm2 in the ink receiving layer. A recording method employing the above-mentioned recording medium is also provided.
