| 摘要 |
The invention provides a method for producing a photographic element which comprises coating a substrate with a positive working photosensitive composition which composition comprises an aqueous alkali soluble resin, a quinone diazide photosensitizer and a solvent composition, heat treating said coated substrate at a temperature of from about 20 DEG C. to about 100 DEG C. until substantially all of said solvent composition is removed; imagewise exposing said photosensitive composition to actinic radiation; baking said coated substrate at a temperature of from about 120 DEG C. to about 160 DEG C. for from about 15 seconds to about 90 seconds; and removing the exposed non-image areas of said composition with a suitable developer.
