PROCESS FOR PRODUCING PATTERN

摘要

A process for producing a pattern, characterized by comprising: a step (a) in which a powder mixture containing a water-soluble inorganic salt powder and a water-soluble organic polymer powder is spread in a plane on a table and then a spray liquid comprising at least one selected among water-miscible organic solvents and water is selectively sprayed through a nozzle on this powder mixture layer to make the bonding strength among particles of the powder mixture in the sprayed region higher than that among particles of the powder mixture in the unsprayed region; a step (b) in which the powder mixture is further spread on the powder mixture layer after spraying and then the spray liquid is sprayed through the nozzle on this powder mixture layer; a step (c) in which the step (b) is conducted repeatedly two or more times to form a pattern formed by the sprayed regions; and a step (d) in which the pattern is taken out.
