In this article, a series of blocked waterborne polyurethanes (BWPUs) were synthesized by isophorone diisocyanate, polyols, dimethylol butanoic acid (DMBA), and 3,5-dimethylpyrazole. BWPUs were applied to digital inkjet printing of textiles. The successful synthesis and deblocking of BWPU were confirmed by Fourier transform infrared spectroscopy and differential scanning calorimetry. The colorfastness was improved by deblocking the terminal NCO groups at 140 C, which could react with fiber. This article presented a characterization method of filtering rate to evaluate the fluency of inkjet printing. Besides, the digital microscope was used to investigate the pigment transferred to the white test cloth. In the end, we chose poly(ethylene glycol adipate) 2000 as the polyol, 1,4-butanediol as the chain extender, 1.6 as the NCO/OH molar ratio, and 4% as the mass fraction of DMBA.

“…2 for the São Jão PS, Nossa Senhora, Santo Alberto b and Mombasa shards confirms that the drawing of the blue decoration was made for these specimens on the unfired (green) body and the glaze powder precursor deposited upon it before the firing. Double-layer glazing was claimed by Wen et al from a cross-sectional image for one shard and explained on the basis of a double glazing step, as reported for the Fujian (Zhangzhou) kilns by Zhou et al 45 and Zhang et al 46 If a double-layer could be recognized on the Mombasa and one of the Santo Alberto(b) shards (Fig. 2) it would be difficult to assign this feature to a double glazing step and it is likely this can be ascribed to the marine corrosion at least for San Alberto (b) shards.…”

“…The comparison using the same ternary diagrams with previous campaigns of XRF measurements, namely upon Vietnamese and Chinese porcelains from Yuan and Ming Dynasty periods [23,26,27,29,[77][78][79][80][81][82][83][84][94][95][96][97][98][99][100][101] will help further the classification of the artifacts (Figure 9). The use of glaze for the analyzed Yuan and Ming ceramics is obvious.…”

“…For a long time, efforts have been made to identify the elements associated with cobalt, allowing the production mining to be identified [23,29,[73][74][75][76][77][78][79][80][81][82][83][84][85][86][87]. Thus, it is considered that during the Yuan Dynasty (1271-1368) the cobalt used was mainly imported from Iran or perhaps even Europe, therefore from the second type [23,[73][74][75][76][77][78][79][80][81][82][83][84][85][86][87], while Asian cobalts (from China, Vietnam and Malaysia/Indonesia), which are rich in Mn and Fe were used [23,26,27,29,[73][74][75][76][77][78][79][80][81][82]…”

In a noninvasive determination, Raman and XRF analyses showed the possibility of identifying specific phases and elements characteristic of the use of recipes and ingredients imported from Europe, according to the information documented in Chinese and European archives. Two sets of objects, supposed to have been produced during the Qing Dynasty (1662–1912) at the Forbidden City (‘imperial bowls’ of the Baur Foundation, Geneva) and in the customs district of Guangzhou (Musée Ariana, Geneva), were analyzed with pXRF and also for some objects with Raman microspectroscopy also on-site. The heterogeneity of the colored zones, in three spatial directions, requires the development of a new methodology. We focused particular attention on the cobalt used in the colored areas and marks, drawn either on the body layer (standard underglaze) or on the glaze itself (overglaze). Comparison is made with previous data on Chinese and Vietnamese porcelains from the Yuan (1271–1368) and Ming Dynasty (1368–1644) periods. Combined data for objects attributed to Guangzhou from the Kangxi and Yongzheng periods indicates the use of the same raw materials containing cobalt, associated with arsenic, nickel, zinc, copper and bismuth, according to the European sources. Similarity of the glaze composition and impurities promotes the production of the glazed body with the same raw materials as those used at Jingdezhen. A consistent shift in data for Qianlong style items, which are significantly richer in manganese, is compatible with their partial mixing with Asian cobalt. The deliberate selection of conflicting objects—namely, examples belonging to the other places of production or different periods—are well-observed outside the ‘Guangzhou’ cluster. Some artifacts have anachronistic purity characteristics that support a production after ca. 1850. For instance, two objects on which certain attributions had been made concerning the stylistic analysis are definitive examples of ceramics using a refined ‘cobalt’, and therefore now may be assigned to the later production period of the first half of the 19th century.
