| description | PROBLEM TO BE SOLVED: To provide an optical information recording medium which does not degrade the printed images by improving the water resistance of the printed part. SOLUTION: This optical information recording medium has ink receiving layers made of a porous film formed on the outermost layer opposite to the recording and reproducing surface. The ink receiving layer is printed in four colors, cyan, magenta, yellow, and black, and the printed surface is dried and immersed for 1 minute in water flowing at a rate of 6 l/min at 20°C for testing. L*a*b* values are measured by using a color-difference meter before and after testing in the flowing water. The total sum of the square roots of the sums of the differences of the L*a*b* values obtained before and after for each colors cyan, magenta, yellow, and black is 20 or less.
