<P>PROBLEM TO BE SOLVED: To provide a high-sensitivity photosensitive composition suitable for use in direct writing with light from a UV lamp and to provide a dry film obtained by applying the composition onto a carrier film and then drying it. <P>SOLUTION: The photosensitive composition is used in direct writing with light from a UV lamp to form a patterned latent image to be developed with an alkaline aqueous solution, wherein a dry coating thereof before light exposure shows an absorbance of 0.6-1.2 in a wavelength range of 355-375 nm and an absorbance of 0.3-0.6 at a wavelength of 405 nm, per 25 μm film thickness of the dry coating. The dry film is obtained by applying the composition onto a carrier film and then drying it. <P>COPYRIGHT: (C)2008,JPO&INPIT |
