| abstract |
The invention relates to colored polyester in solid form, characterized in that the colored polyester is obtained by polymerizing components comprising a) one or more aromatic dicarbolic acids having no sulfogroups and/or the salts thereof and/or the anhydrides thereof and/or the esters thereof, b) optionally one or more dicarbolic acids having sulfogroups and/or the salts thereof and/or the anhydrides thereof and/or the esters thereof, c) one or more dioles, d) optionally one or more compounds of the formula (1) n R 1 O(CHR 2 CHR 3 O) n H (1)n n where R 1 is a linear or branched, saturated or unsaturated alkyl group having 1 to 22 C atoms, R 2 and R 3 are, independent of each other, hydrogen or an alkyl group having 1 to 4 carbon atoms, and n is a number from 1 to 50, e) optionally one or more compounds of the formula (2) n H—(OCHR 2 CHR 3 ) m —SO 3 X (2)n n where R 2 and R 3 are, independent of each other, hydrogen or an alkyl group having 1 to 4 carbon atoms, and m is a number from 1 to 10, and X is hydrogen or an alkali metal ion, and f) optionally one or more polyfunctional compounds having a crosslinking effect and having 3 to 6 functions enabled for polycondensation, in particular acid, alcohol, or ester functions, under the condition that at least one of the components d) or e) is present, in the presence of g) one or more pigment(s). |
