Abstract: A water-soluble, positive-working photoresist composition is disclosed which comprises water-soluble aromatic diazonium salt, water-soluble phenolic compound, and water-soluble polymeric compound. When the film of this composition is irradiated with a pattern of actinic ray and then brought into contact with an alkaline gas or solution, the coating of unexposed areas hardens to become water-insoluble. Preferably, when the film is brought into contact with a suspension of powder or dry powder after being hardened, a positive pattern of powder is obtained by the development with water.
