The invention discloses an acid-soluble phthalocyanine dye and a manufacturing method thereof. The use is simple, the operation can be easily controlled, and the color of the dyed textile is uniform and bright. The acid-soluble phthalocyanine dye is a dye with transiently soluble groups formed by complexing two amine groups on a central metal ion of phthalocyanine, so that the metal phthalocyanine has solubility and can be directly dissolved in diluted acid when in use. After dying is completed, the transiently soluble groups can be decomposed and removed through reduction, and the insoluble metal phthalocyanine can be left on the fabric. The acid-soluble phthalocyanine dye can be prepared through mixing phthalocyanine compounds, amines and ammonium chloride, filling oxygen and heating.
