Claims
- 1. A process for pigmenting a high molecular weight organic material in the mass comprising incorporating into said high molecular weight organic material a soluble chromophore of formulaA(B)x, (I), wherein x is an integer from 1 to 5, with the proviso that x is at most equal to the total number of H-atoms attached to the N-atoms of the radical, A is the radical of a chromophore of the quinacridone, 1-amino-anthraquinone, indanthrone, perylene, indigo, quinophthalone, isoindolinone, isoindoline, triphenedioxazine, phthalocyanine or azo series, which radical contains x B groups attached to N-atoms, B is a group of formula or, when x is 2, 3, 4 or 5, B may also be hydrogen, with the proviso that at least one B is formula (II), (III) or (IV), m, n and p are each independently of one another 0 or 1, X is C1-C14alkylene or C2-C8alkenylene, Y is a group —V—(CH2)q—, Z is a group —V—(CH2)r—, V is C3-C6cycloalkylene, q is an integer from 1 to 6, and r is an integer from 0 to 6, R1 and R2 are each independently of the other hydrogen, C1-C6alkyl, C1-C4alkoxy, halogen, CN, NO2, unsubstituted phenyl or phenoxy or phenyl or phenoxy which are substituted by C1-C4alkyl, C1-C4alkoxy or halogen, Q is hydrogen, CN, Si(R1)3; a group C(R5)(R6)(R7), wherein R5, R6 and R7 are each independently of one another hydrogen or halogen and at least one of R5, R6 and R7 is halogen; a group wherein R1 and R2 are as defined above;a group SO2R8 or SR8, wherein R8 is C1-C4alkyl; a group CH(R9)2, wherein R9 is unsubstituted phenyl or phenyl which is substituted by C1-C4alkyl, C1-C4alkoxy or halogen; or a group of formula R3 and R4 are each independently of the other hydrogen, C1-C18alkyl, a group wherein X, Y, R1, R2, m and n are as defined above, or R3 and R4, together with the linking nitrogen atom, form a pyrrolidinyl, piperidinyl or morpholinyl radical, and then converting said chromophore of formula (I) into a pigment of the formula A(B)x by thermal, photolytic or chemical degradation in situ.
- 2. A process according to claim 1 wherein the high molecular weight organic material comprises a polymer.
- 3. A process according to claim 2, wherein the polymer is in the form of a fiber.
- 4. A process according to claim 1 wherein the high molecular weight organic material comprises a paint system.
- 5. A process according to claim 1 wherein the high molecular weight organic material comprises a printing ink.
- 6. A process according to claim 5, wherein the printing ink comprises a toner.
- 7. A process according to claim 5, wherein the printing ink comprises an ink jet printing ink.
- 8. A process according to claim 1, wherein x is 1 or 2 and B is a group of formula and, if x is 2, may also be one hydrogen atom, and in formulae IV, V and VIm is 0 or 1, X is C1-C4alkylene or C2-C5-alkenylene, R1 and R2 are each independently of the other hydrogen, C1-C4alkyl, methoxy, chloro or NO2, and Q is hydrogen, CN, CCl3, a group SO2CH3 or SCH3,R3 and R4 are each independently of the other C1-C4alkyl or a group or R3 and R4, taken together, form a piperidinyl radical.
- 9. A process according to claim 1, wherein x is 2 and B is a group of formula and the number of groups B is two.
