Title:
COATING METHOD OF WATER PAINT AND IMAGE FORMING METHOD
Document Type and Number:
Japanese Patent JP3263219
Kind Code:
B2
Abstract:
PURPOSE: To uniformly apply a water paint for forming a color pattern in thin film thickness by forming a pattern on a substrate by using a positive photoresist and after irradiating with electromagnetic radiation, applying the water paint.
CONSTITUTION: The water paint is uniformly applied on the pattern of the positive photoresist by applying the water paint after irradiating the resist pattern on the substrate with electromagnetic radiation. That is, the water paint is uniformly applied by irradiating the positive photoresist pattern with electromagnetic radiation, e.g. ultraviolet ray, to make the surface of the resist hydrophilic. And at the time of lift-off, since the pattern of the positive photoresist is made easily soluble in alkali, the pattern formed by the water paint becomes sharp and the residue of the positive photoresist does not remain at the edge or corner part of the pattern.
