发明名称 Use of mono- and dicationic naphthalene-based imide dyes in optical layers for optical data recording
摘要 The present invention relates to the use of mono- and dicationic naphthalene-based imide dyes known as charge control agents, antistatic agents or optical brighteners as dyes in optical layers for optical data recording. <??>In particular, the present invention relates to optical layers comprising as dyes mono- or di-cationic naphthalene tetracarboxylic di-imide with high-performance anions as counterions, such as tetracyanoquinodimethane (TCNQ-), tetraphenylborate or hexafluoroantimonate. <??>The invention further relates to a write only read many (WORM) type optical recording media capable of recording and reproducing information with radiation of blue laser, which comprises a mono- or di-cationic naphthalene tetracarboxylic di-imide type dye in the optical layer.
