ABSTRACT:
An optical information recording medium comprises resin-recording layers respectively made of polymers each carrying a dye. The layers are laminated on a substrate in such a manner that the first and second layer in the resin-recording layers directly adjoin each other. The first polymer constructing the first layer has a solubility to be insoluble to the second solvent capable of dissolving the second polymer constructing the second layer. The second polymer has a solubility to be insoluble to a first solvent capable of dissolving the first polymer.
