| These indene polymers are suitable as dispergents, for example in dyestuff and pigment compositions. |
| The high price of this dyestuff causes its employment to be somewhat limited. |
| One example is the story of the clarification of the chemical structure of Perkin's mauve, the first synthetic dyestuff. |
| Under the deep-furrowed, brown surface bark is a yellow layer, rich in tannin, and a dyestuff called quercitron. |
| Crimson comes ultimately from the name of a small insect from which a red dyestuff is obtained. |
| The pink layer was characterized as a reddish pink lake or dyestuff by PLM analysis. |
