<p>A process for producing a radiation-sensitive resin composition, comprising the step of providing a filter apparatus equipped with a filter composed of a polyamide resin filter and a polyethylene resin filter connected in series and circulating a precursor composition for radiation-sensitive resin composition in the filter apparatus so that the precursor composition is passed through the filter two or more times to thereby effect filtration with the result that foreign matter is removed from the precursor composition.</p> |
