Encapsulation of phthalocyanine pigments onto hyperbranched polyesters ( HBP s) is reported for in situ printing ellulosic fabrics. The encapsulation was developed through liquid‐phase separation method approached using various functional hydroxyl groups in HBP s; generation 2 ( HBP s16) and generation 4 ( HBPs64 ). The HBP s‐encapsulated pigment was characterized with thermal gravimetric analysis, environmental scanning/transmission electron microscope, Fourier transform infrared spectroscopy, dynamic light scattering, X‐ray diffraction pattern, and contact angle analysis. The characterization demonstrated the successful encapsulation of phthalocyanine pigments into HBP s. It was shown that the encapsulated pigments improved the pigment print fixation on cellulosic fabrics immediately in one step and decreased the requested amount of the binder and fixation temperature relative to the control sample. The color strength and light fastness were greatly influenced by the generations of hyperbranched polyesters.
