An ink composition comprised of a colorant and an imide or bisimide with a viscosity of from about 1 centipoise to about 10 centipoise at a temperature of from about 125.degree. C. to about 180.degree. C., and which imide or bisimide is of the Formulas I or II, respectively: ##STR1## wherein R is a hydrocarbon of from about 2 to about 50 carbon atoms; R' is an alkylene hydrocarbon or a polyalkyleneoxide, each with from about 2 to about 30 carbon atoms; and X is an arylene of from 6 to about 24 carbon atoms, or an alkylene of from about 2 to about 10 carbon atoms.

A wholly aromatic polyester composition comprising
(a) 100 parts by weight of a wholly aromatic polyester containing as a main component at least one compound selected from the group consisting of aromatic dicarboxylic acids, aromatic dihydroxy compounds and aromatic hydroxycarboxylic acids, and
(b) from 5 to 300 parts by weight of a low-molecular-weight compound being substantially non-reactive with the wholly aromatic polyester and having a boiling point of at least about 200°C under atmospheric pressure and a molecular weight of not more than 1.000.
The wholly aromatic polyester composition is produced advantageously by polycondensing in the molten state the polyester-forming starting mixture in the presence of the low-molecular-weight compound.
A film-like or fibrous article of a wholly aromatic polyester may be produced by extracting the low-molecular-weight compound from a film-like or fibrous article of the wholly aromatic polyester composition.

A process for producing a film-like or fibrous structure of an aromatic polyester, which comprises
(1) forming an unstretched film-like or fibrous structure by melt-shaping a blend comprising 100 parts by weight of (A) an aromatic polyester having a high degree of polymerization derived from an aromatic dicarboxylic acid as a main acid component and an aliphatic diol and/or an alicyclic diol as a main glycol component and (B) 3 to 300 parts by weight of a low-molecular-weight compound being substantially non-reactive with the aromatic polyester (A) and having a boiling point of at least about 200°C under atmospheric pressure and a molecular weight of not more than 1,000,
(2) stretching the resulting film-like or fibrous structure,
(3) extracting at least a major portion of the low-molecular-weight compound from the stretched film-like or fibrous structure by using an organic solvent which does not substantially dissolve the aromatic polyester under the extracting conditions, and
(4) if desired, heat-setting the film-like or fibrous structure after the stretching step (2) and/or the extracting step (3).
The film-like or fibrous structure of an aromatic polyester prepared by the process substantially contains no low-molecular-weight compound or contains the low-molecular-weight compound in an amount of up to about 1 part by weight at most per 100 parts by weight of the aromatic polyester.

Die Erfindung betrifft Polyesterformmassen bestehend im wesentlichen aus dem Polyester, vorzugsweise Polyethylenterephthalat, einem Nukleierungsmittel, einer speziellen Imidverbindung als weiterem Kristallisationsbeschleuniger sowie gegebenenfalls den üblichen Verstärkungsmitteln und Zusatzstoffen. Der spezielle erfindungsgemäße Kristallisationsbeschleuniger ist praktisch nicht reaktiv mit dem Polyester und insbesondere erheblich migrations-beständiger als einschlägige Kristallisationsbeschleuniger gemäß Stand der Technik. Die Erfindung hat weiterhin ein Verfahren zur Herstellung dieser Polyesterformmassen zum Gegenstand.
