description One inventive aspect relates to an optical information recording medium, in which the quality of a printed image is not impaired because the water resistance of a printed portion is improved. The optical information recording medium includes a porous film ink receiving layer as an outermost layer of a surface opposite to a recording and playback surface, wherein when the ink receiving layer is printed with an ink of each of four colors, cyan, magenta, yellow, and black, followed by drying, a running water test is performed, and L*a*b* values before and after the running water test are measured with a colorimeter, the total value of the square root of the sum of the square of difference in L*, the square of difference in a*, and the square of difference in b*, each between before and after the running water test, of each of the four colors is approximately 20 or less.
