Product Name:Black-1
English Name:Black-1
CAS No.:29512-49-0
Aliases:ODB-2, 2-Anilino-3-methyl-6-(diethylamino)fluoran, Thermal dye Black-1
Molecular Formula:C27H28N2O3
Physical Properties:Off-white powder; purity ≥99.0%; melting point ≥194.0°C; volatile content ≤0.5%; insoluble matter ≤0.2%; ash content ≤0.2%. It is generally insoluble in water and soluble in organic solvents such as benzene, acetone, and ethyl acetate. It develops black color by lactone ring opening under the action of a developer.
Uses:Used as a black color former for thermal (pressure-sensitive) paper in the papermaking industry. The product is usually a colorless or light-colored crystal; when contacting a developer (acid clay, bisphenol A, POB, etc.), it develops color as the intramolecular lactone ring opens, featuring high color density, fast response, and good stability.
Technical Specifications:
Appearance: off-white powder
Purity: ≥99.0%
Melting point: ≥194.0°C
Volatile content: ≤0.5%
Ash content: ≤0.2%, insoluble matter: ≤0.2%
