Abstract:
The present invention relates to the use of pyridine N-oxide based azo dyes and their metal complexes in optical layers for optical data recording, preferably for optical data recording using a blue laser with a wavelength up to 450 nm or a red laser with a wavelength up to 650 nm. The invention further relates to a write only read many (WORM) type optical recording medium capable of recording and reproducing information with radiation of a blue or red laser, which employs a pyridine N-oxide based azo dye or a respective metal complex in the optical layer.

Abstract:
Die Erfindung betrifft Monoazo-, Disazo- und Trisazo-Farbmittel der Formel (I), worin M für zwei Wasserstoffatome steht, oder ein Metallion aus der Gruppe Cu, Co, Ni, Mn, Zn und Al bedeutet; A den Rest eines substituierten Naphthyl- oder Pyrazolylrestes bedeutet.
Abstract:
A water-soluble complex dye capable of forming an image having light resistance, ozone resistance, and high saturation; a water-based recording fluid especially for ink-jet recording which contains the dye; and a method of ink-jet recording. The water-soluble complex dye comprises: an azo compound represented by the following general formula (1) or a tautomer thereof; and transition metal ions. The method of ink-jet recording comprises using the recording fluid. (1) In the general formula (1), A represents either a 5- to 7-membered heteromonocyclic group containing three or four heteroatoms among the ring-constituting atoms or a fused heterocyclic group including the heteromonocycle and can have any desired substituent, provided that the group does not have substituent hydroxy in the positions adjacent to the carbon atom bonded to the azo group; ring X represents a fused heterocycle which includes a 6-membered heterocycle bonded to the azo group and optionally has any desired substituent; and R and R each independently represents hydrogen or a monovalent substituent.
