FIELD: optical data carriers. n SUBSTANCE: device has cation dye or mixture of cation dyes with optical characteristics, changed by means of recording beam, an at least one substance with functions of damper and phenol or substituted phenol with one hydroxide group or more, while it additionally contains phenol or substituted phenol in form of phenolate ion, forming a portion of anions for dye cations, as a stabilizer. Data carrier can contain anionic metal-organic thyolene complex as damper, which forms other portion of anions for dye cations. n EFFECT: higher stability, higher durability, lower costs. n 5 cl, 1 tbl, 3 ex |
