Abstract:
A process for mass colouration of a polymer, which comprises adding at least one compound of the formula (I)A(B)xâ€ƒâ€ƒ(I) where x is an integer from 1 to 8, A is the radical of a chromophore of the quinacridone, anthraquinone, perylene, indigo, quinophthalone, indanthrone, isoindolinone, isoindoline, dioxazine, azo, phthalocyanine or diketopyrrolopyrrole series, this radical being linked with x B groups via one or more heteroatoms, these heteroatoms being selected from the group consisting of N, O and S and forming part of the radical A, and B is hydrogen or a group of the formula wherein at least one B group is not hydrogen and when x is from 2 to 8 the B groups may be identical or different, E1 is oxygen or is selected from the group consisting of methylene, methyleneoxy and ethylene, each member of the group being unsubstituted or substituted by one R5 or by 2 radicals, R5 and R6, or is two separate radicals, R7 and R8, R7 being attached to the same atom as R1 and R8 to the same atom as R4, E2 is selected from the group consisting of methylene, ethylene, propylene and butylene, each member of the group being unsubstituted or substituted by one R9 or by 2 radicals, R9 and R10, or is two separate radicals, R11 and R12, R11 being attached to the same atom as R1 and R12 to the same atom as R4, G1 is O or N(R13), R1 is hydrogen, methyl, ethyl, methoxy or ethoxy, R2 and R3 are independently hydrogen, C1-C8alkyl, C1-C8alkoxy, C1-C8alkoxy-C2-C8alkylene or C1-C8alkoxy-C2-C8alkyleneoxy, R4 is hydrogen, C1-C8alkyl, C1-C8alkoxy, C1-C8alkoxy-C2-C8alkylene, C1-C8alkoxy-C2-C8alkyleneoxy, C5-C6cycloalkyl, C5-C6cycloalkoxy, phenyl, phenoxy or a 5- or 6-membered, saturated or singly to triply unsaturated heterocyclic radical, R5, R6, R9, R10 and R12 are independently C1-C8alkyl or C1-C8alkoxy, or R6 and R9 together are a direct bond, R7 and R8 are independently hydrogen, C1-C8alkyl, C1-C8alkoxy, C1-C8alkoxy-C2-C8alkylene or C1-C8alkoxy-C2-C8alkyleneoxy, R11 is hydrogen, C1-C8alkyl or C1-C8alkoxy, R13 is methyl or ethyl, and R14 is C1-C8alkyl, C5-C6cycloalkyl, phenyl or a 5- or 6-membered, saturated or singly to triply unsaturated heterocyclic radical, it being possible for two methoxies attached to the same carbon atom to combine and form 1,2-ethylenedioxy, or for methoxy to combine with ethoxy attached to the same carbon atom to form 1,2- or 1,3-propylenedioxy, or for methoxy or ethoxy to combine with ethoxy attached to &agr;- or &bgr;-enchained carbon to form dimethylmethylene, and where additionally a) R1, R2, R3, R7 or R11 is hydrogen, and b) when E1 is two separate radicals R7 and R8 and E2 is methylene or ethylene at least one of the following further conditions applies: R1, R2, R3, R4, R7, R8, R9 or R10 is methoxy or ethoxy; R2, R3, R4, R7, R8, R9 or R10 is secondary C3-C8alkyl or tertiary C4-C8alkyl or C3-C8alkoxy; R2, R3, R7 or R8 is C1-C8alkoxy-C2-C8alkylene or C1-C8alkoxy-C2-C8alkyleneoxy; or R4 is C5-C6cycloalkyl, C5-C6cycloalkoxy, phenyl, phenoxy or a 5- or 6-membered heterocyclic radical to the polymer before or during processing, the processing taking the form of extrusion, injection moulding or fibre spinning at 220 to 330Â° C.
