Problems solved by technology

The object of the present invention is to provide an optical information recording medium, which can solve the problem that the ink receiving layer directly formed on the optical information recording medium has insufficient water resistance after printing, and the problem occurs when the label surface is handled with fingers or the like. The above-mentioned problems such as color fading that may damage the print quality, and by improving the water resistance of the printed part, the print image quality will not be damaged

Abstract

The invention provides an optical information recording medium which does not degrade the printed images by improving the water resistance of the printed part. 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 DEG 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, andblack is 20 or less.

Description

technical field The present invention relates to an optical information recording medium having an ink-receiving layer capable of direct printing on the side (label side) opposite to the recording and reproduction side of the optical information recording medium, and having excellent printing water resistance. Background technique Currently, the use of optical information recording media having an ink-receiving layer directly printable with an ink jet printer or the like on the label side (so-called printable products) is gradually expanding. Here, since the ink-receiving layer of a printable product can absorb and fix the water-based ink of an inkjet printer to print images or characters, the layer is usually composed of a material mainly composed of a hydrophilic resin. On the other hand, since the ink receiving layer has a hydrophilic function, it has a disadvantage of poor water resistance. In addition, unlike the usual case of printing on paper, there are two functio...
