Abstract: Evaporated squarilium-based, malonitrile-based merocyanine, metal-complexes on dithiolate base, ketocyanine and phtalocyanine (Pc) dyes form smooth films, which show high optical absorption and reflection in visible and near- infrared regions. Co-deposition of polytetrafluoroethylene (PTFE) and Pc dyes showed that the films obtained consist of the PTFE matrix filled by Pc particles of 10 - 30 nm size. Recording on dye film is performed in ablative mode by 9 mW of semiconductor laser, if PTFE sublayer is used. Three types of hole opening mechanisms were obtained by choosing dye and substrate with properties needed.!8
