Abstract
A two-photon absorbing optical recording material comprising at least one two-photon absorbing compound and a recording component is provided. Recording is made on it by utilizing the two-photon absorption of the two-photon absorbing compound in the material, and then the material is irradiated with light to thereby detect the difference in the reflectance between the recorded area and the unrecorded area thereof, and the recorded information is thereby reproduced from the material, and also provided are a photosensitive polymer composition and a photon-mode recording method for the material.
