PURPOSE: To obtain a compsn. excellent in various properties such as profile, appliability and heat resistance by incorporating a quinonidiazido compd., an alkali-soluble resin and a solvent system contg. 2-heptanone, ethyl lactate andγ-butyrolactone. CONSTITUTION: This compsn. contains a quinonediazido compd., an alkali-soluble resin and a solvent system contg. 2-heptanone, ethyl lactate andγ-butyrolactone. The quinonediazido compd. is usually quinone diazidosulfonic ester, especially o-quinonediazidosulfonic ester of a compd. having a phenolic hydroxyl group. The o-quinonediazidosulfonic ester is, e.g. 1,2-benzoquinonediazido-4-sulfonic ester. Such o-quinonediazidosulfonic ester can be produced by condensing a compd. having a phenolic hydroxyl group and o-quinonediazidosulfonic acid halide in the presence of an org. or inorg. base. |
