摘要:
The present invention relates to a process for dyeing or printing manufactured natural polymer or synthetic hydrophobic fibre materials, characterized in that it comprises using dyes of the formula (I), where R1 is hydrogen, hydroxyl or a radical -NHCO-R6, where R6 is C1-C6alkyl or unsubstituted or C1-C4alkyl- or halogen-substituted phenyl, R2 is hydrogen, hydroxyl or a radical W-R7, where W is -NHCO- or -S- and R7 is C1C6alkyl or unsubstituted or C1-C4alkyl- or halogen-substituted phenyl, R3 is hydrogen, R4 is hydrogen or hydroxyl, R5 is hydrogen, halogen, methoxy, phenoxy or phenylthio, or R3 and R4 combine to form the radical of the formula (II), where the rings A and B may independently bear further substituents, to the use of these dyes for trichromatic dyeing of manufactured natural polymer or synthetic hydrophobic fibre materials and mass dyeing of plastics materials and to producing solid on-tone combinations of plastics material and manufactured natural polymer or synthetic fibre material.
摘要:
Quinacridone pigments that are surface-functionalized with glycidyl methacrylate, maleic anhydride, or 4-methacryloxyethyl trimellitic anhydride to create a functionalized pigment. The functional groups are then activated to bond hydrophobic polymers, thereby coating the pigment with the hydrophobic polymers. The quinacridone pigments can be used for a variety of applications. They are well-suited for use in electro-optic materials, such as electrophoretic media for use in electrophoretic displays.
摘要:
The present application relates to a process for preparing dyed plastics or polymeric dye particles characterized in that it comprises mixing a high molecular weight organic material with a coloristically effective amount of at least one dye of the formula where R1 is hydrogen, hydroxyl or a radical -NHCO-R6, where R6 is C1-C6alkyl or unsubstituted or C1-C4alkyl- or halogen- substituted phenyl, R2 is hydrogen, hydroxyl or a radical W-R7, where W is -NHCO- or -S- and R7 is C1-C6alkyl or unsubstituted or C1-C4alkyl- or halogen-substituted phenyl, R3 is hydrogen, R4 is hydrogen or hydroxyl, R5 is hydrogen, or R3 and R4 combine to form the radical of the formula, where the rings A and B may independently bear further substituents.
