(57) [Summary] [Purpose] To provide a positive resist composition excellent in various properties such as resolution and heat resistance, and a method for easily producing a color filter excellent in various properties such as solvent resistance and fineness. To do. [Structure] A positive resist composition containing a thermosetting resin, a quinonediazide compound, a cross-linking agent, a dye and a solvent, and after coating the positive resist composition on a substrate, A method for producing a color filter, which comprises exposing through a mask, developing the exposed portion to form a positive resist pattern, exposing the whole positive resist pattern, and then curing the exposed positive resist pattern. |
