ABSTRACT:
There are provided a photosensitive composition used in one-shot exposure of exposing it via a photomask to light from a UV lamp or in direct writing with light from a UV lamp or laser light to form a patterned latent image to be developed with an alkaline aqueous solution, wherein a difference between maximum absorbance and minimum absorbance, in a wavelength range of 355 to 405 nm, of a dry coating thereof before light exposure is within 0.3 per 25 μm film thickness of the dry coating, and a dry film obtained by applying the photosensitive composition onto a carrier film and then drying it.
