PURPOSE: To manufacture paint used for a screen sealing die in a short time without restricting by an available time by using one-pack type moisture curable polyurethane resin paint of polyurethane resin paints.

CONSTITUTION: A gauze made of a material such as polyester, etc., is adhered to a framework and fixed. Then, the fixed gauze is coated with photosensitive liquid, and dried in a dark place to manufacture a photosensitive film. After the film is printed in a desired pattern with a light, the film is developed by washing. Thus, the gauze of the residual pattern is obtained, the gauze of the pattern is dried, then coated with one-pack type moisture curable polyurethane resin, and left to stand for a predetermined time at the ambient temperature to be cured, thereby obtaining a screen sealing die. Thus, the die can be manufactured in a short time without restricting with an available time, and its manufacturing efficiency becomes preferable.
