A method of manufg. a color picture tube comprises; the steps of coating phosphors of three primary colors on the inner surface of the face plate of the color picture tube to form dots or stripes of the phosphors, applying an acrylic resin emulsion on the phosphors to form an acrylic resin film vapor depositing metal onto the film to form a metallic reflecting film, subjecting the acrylic resin film to a pyrolysis for decomposing it into gases, and removing the gases. It is possible to prevent bulging of the metallic reflecting film during baking step while minimizing the number of the pin holes and cracks of the metallic reflecting film so as not to decrease the brightness of the produced picture.
