摘要:
The invention relates to novel metal complexes for optical data carriers, whereby the latter preferably a transparent substrate which is, optionally, already covered with one or several reflective layers. A light-inscriptible information layer is disposed on the surface thereof, in addition to, optionally, one or several reflective layers and, optionally, a protective layer or another substrate or a covering layer which is inscriptible or readable with blue, red or infrared light, preferably laser light. The information layer contains a light-absorbing compound and, optionally, a binding agent. The invention is characterised in that the at least said metal complex is used as a light-absorbing compound.
摘要:
Disclosed are optical data storage devices comprising at least one information layer that contains a polymeric network with covalently bonded light-absorbable compounds.
摘要:
Disclosed are novel metal complexes for an optical data carrier comprising a preferably transparent substrate which is optionally coated with one or several reflection layers, and to the surface of which an information layer that is writable by means of light, one or several optional refection layers, and an optional protective layer or another substrate or a covering layer are applied. Said data carrier is writable and readable by means of blue light or red light, preferably laser light. The information layer is provided with a light-absorbing compound and an optional bonding agent. The invention is characterized by the fact that at least said metal complex is used as a light-absorbing compound.
摘要:
The invention relates to optical data carriers containing a preferably transparent substrate that is optionally already coated with at least one reflective layer. An information layer on which data can be written with light, optionally at least one reflective layer, and optionally a protective layer or another substrate or a covering layer, are applied to the surface of said substrate, and can be written on or read with a blue light, preferably light having a wavelength of between 360-460 nm, especially between 390 and 420 nm, preferably between 400 and 410 nm, and preferably laser light. The information layer contains a light-absorbent compound and optionally a binding agent. The inventive data carriers are characterised in that at least one metallic complex is used as a light-absorbent compound, comprising at least one ligand of formula (I) wherein (A) represents an optionally substituted and/or benzene-annelated or naphthane-annelated, five or six-membered, aromatic or quasi-aromatic or partially hydrated, heterocyclic radical, n represents 0 or 1, Y1 represents N or C-R1, Y2 represents N or C-R2, Y3 represents N or C-R3, X represents O, S or N-R5, R5 represents hydrogen, alkyl, alkenyl, aralkyl, cycloalkyl, acyl, aryl or a heterocyclic radical, Rl to R4 independently represent hydrogen, halogen, alkyl, alkoxy, monoalkylamino or dialkylamino, aralkyl, aryl, hetaryl, arylazo, hetarylazo, cyano or alkoxycarbonyl, R1; R2, R2; R3 and R4; R5 can respectively form a bridge independently from each other, and R2; R5 can form a bridge when n is 0.
