Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 49 N° 2 (Janvier 2010) . - pp 541–547 Titre : Pigmentation of boc-indanthrone in organic solvent/photopolymer through a thermal process Type de document : texte imprimé Auteurs : Liu, Tang-Hao, Auteur ; Wen-Tung Cheng, Auteur ; Huang, Kuo-Tung, Auteur Année de publication : 2010 Article en page(s) : pp 541–547 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Organic solvent photopolymer Thermogravimetric. Résumé : This work explores a pigment converted from a latent pigment in organic solvent and photopolymer through a thermal process. Measurements by thermogravimetric analysis (TGA), ultraviolet−visible (UV−vis) spectroscopy, and Fourier transform infrared (FTIR) spectroscopy showed that regeneration of the pigment from boc-indanthrone in the solvent or photopolymer could be achieved by heating. X-ray diffraction (XRD) was employed to characterize the regenerated pigments. As shown in the results, the recrystallized structure is similar to the structure of the parent pigment. Analysis using field-emission scanning electron microscopy (FESEM) indicated that the particles of the re-formed pigment in the solvent were initially cubic, then aggregated into loose bars, and finally became firmly slated and flat for hydrogen-bonding and π−π stacking interactions. In addition, the morphology of the reproduced pigment was found to be cubic, as in the photopolymer.
