| titleOfInvention |
Triazolylcoumarin compounds, and their preparation and use as optical brighteners, scintillators and laser dyestuffs |
| abstract |
Optical brighteners of the formula <IMAGE> wherein B denotes a direct bond or the 1,4-phenylene radical and R1 and R2 independently of one another denote hydrogen, optionally substituted alkyl, aralkyl, cycloalkyl or aryl, or together form a fused aromatic ring, or the quaternisation products and protonation products thereof, are outstandingly suitable for the white tinting of polyester fibres or acrylic fibres. They are distinguished by a good build-up capacity and a small tendency to develop a green tone. |
