Abstract
A photosensitive resin film and application thereof are provided. When the photosensitive resin film is subjected to a thermogravimetric analysis under the conditions of heating at a rate of 5° C./min from 40° C. to 200° C. and then keeping the temperature at 200° C. for 10 min, the absolute value of the first derivative of the weight percentage with respect to time within the range of 0 to 40 min is higher than 0.1%/min and not higher than 1.0%/min.
Claims15
A photosensitive resin film, wherein when the photosensitive resin film is subjected to a thermogravimetric analysis under the conditions of heating at a rate of 5° C./min from 40° C. to 200° C. and then keeping the temperature at 200° C. for 10 min, the absolute value of the first derivative of the weight percentage with respect to time within the range of 0 to 40 min is higher than 0.1%/min and not higher than 1.0%/min;
- wherein the photosensitive resin film has a thickness of 60 μm to 600 μm;
- and
- wherein the photosensitive resin film comprises:
- (A) an alkali-soluble polymer;
