SOLUBLE CHROMOPHORES HAVING IMPROVED SOLUBILISING GROUPS

摘要

Compounds of formula (I): A(B)x wherein 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 that is bonded to x groups B via one or more hetero atoms, those hetero atoms being selected from the group consisting of N, O and S and forming part of the radical A; each group B independently of any other(s) is hydrogen or a group of formula .alpha., at least one group B being a group of said formula, wherein Q is p, q-C2-C12alkylene that is unsubstituted or mono- or poly-substituted by C1C12alkoxy, C1-C12alkylthio or by C2-C24dialkylamino, p and q being different position numbers; X is a hetero atom selected from the group consisting of N, O and S, m being the number 0 when X is O or S and m being the number 1 when X is N, and L1 and L2 are each independently of the other ¢-(p',q'-C2-C12alkylene)-Z-!n-C1-C12alkyl or C1-C12alkyl that is unsubstituted or mono- or poly-substituted by C1-C12alkoxy, C1-C12alkylthio, C2-C24dialkylamino, C6C12aryloxy, C6-C12arylthio, C7-C24arylalkylamino or by C12-C24diarylamino, wherein n is a number from 1 to 1000, p' and q' are different position numbers, each Z independently of any other(s) is a hetero atom O, S or C1C12alkyl-substituted N, and C2-C12alkylene in the repeating units ¢-C2-C12alkylene-Z-! may be identical or different; and L1 and L2 may be saturated or one- to ten-fold unsaturated, uninterrupted or interrupted at any desired points by from 1 to 10 groups selected from the group consisting of -(C=O)-and -C6H4-, and may carry no substituents or may carry from 1 to 10 further substituents selected from the group consisting of halogen, cyano and nitro; with the proviso that when -Q- is -(CH2)r-, wherein r is a number from 2 to 12, and X is S, L2 may not be unsubstituted, saturated and uninterrupted C1C4alkyl. The compounds according to the invention are used in high-molecular-weight organic materials, thermo-, photo- or chemo-sensitive recording materials, light-sensitive negative or positive resist compositions, ink compositions for ink-jet printing and colour tapes for thermal transfer printing.
