Abstract: A greatly improved printing screen used for screen printing is provided in respect of the durability in printing, resistance against solvents and antistatic performance based on a mesh of polyester or nylon filaments. According to the invention, the base mesh is subjected to exposure to low temperature plasma of an inorganic gas prior to coating with a photosensitive resin composition in the form of an aqueous emulsion. When the plasma-treated mesh is coated, prior to coating with the photosensitive resin emulsion, with a surface active agent or when the photosensitive resin emulsion is admixed with a surface active agent, further improvement can be obtained in the antistatic performance of the screen. When a base screen dyed in yellow is used, the drawbacks caused by halation in the pattern-wise exposure of the screen to light can be greatly reduced.
