UV-curable hyperbranched polyester acrylate is formulated for encapsulation of phthalocyanine pigments using liquid-phase separation method. The encapsulated pigments were used as a UV-curable binder incorporated the pigment colours to eliminate the solid content, slow dry rate and hardness of conventional UV curable systems. Thermal gravimetric analysis (TGA), transmission electron microscope (TEM), Fourier transform infrared spectroscopy (FTIR), dynamic light scattering (DLS) and X-ray diffraction pattern (XRD) were examined in details. The characterization demonstrated the successful encapsulation of phthalocyanine pigments via UV-curable hyperbranched polyester acrylate. Thermal gravity analysis indicates that the encapsulated pigment films have better thermal stability than the pure pigments. The roughness and colour fastness to rubbing, washing, and light of the printed fabrics by encapsulated pigment, were compared to the same fabrics printed by conventional pigment printing using the UV curable formulation system with the linear counterpart of polyester acrylate as well as the conventional UV curable binder. The results showed that the printed samples with encapsulated pigment displayed the highest colour strength compared with the conventional printed samples. Additionally, the UV-curable hyperbranched polyester acrylate can be cured by short exposure to UV light and eliminate the surface roughness effect of UV curable system, decreased the solid content which increased the durability properties, rubbing and washing of printed fabrics.

紫外光固化的超支化聚酯丙烯酸酯采用液相分离法配制用于酞菁颜料的封装。所述包封的颜料被用作掺入颜料的颜色，以消除固体含量，慢干率和硬度常规UV可固化体系的可UV固化粘合剂。详细检查了热重分析（TGA），透射电子显微镜（TEM），傅立叶变换红外光谱（FTIR），动态光散射（DLS）和X射线衍射图（XRD）。表征表明，可通过紫外线固化的超支化聚酯丙烯酸酯成功封装酞菁颜料。热重分析表明，包封的颜料膜具有比纯颜料更好的热稳定性。将封装的颜料对印刷织物的粗糙度和色牢度，耐摩擦性，耐洗性和耐光性与使用紫外线可固化配方体系，聚酯丙烯酸酯的线性对应物以及常规紫外线通过常规颜料印刷的相同织物进行比较可固化的粘合剂。结果表明，与常规印刷样品相比，具有包封颜料的印刷样品显示出最高的色强度。另外，紫外线可固化的超支化聚酯丙烯酸酯 可以通过短时间暴露在紫外线下而固化，并消除了紫外线固化体系的表面粗糙度影响，减少了固含量，从而增加了耐用性，印花织物的摩擦和洗涤。
