A chemically amplified photosensitive composition which forms a resist pattern whose cross-sectional shape is rectangular, and which has a wide depth of focus margin; a photosensitive dry film having a photosensitive layer made from the composition; a method of manufacturing a patterned-resist film using the composition; a method of manufacturing a substrate with a template using the composition; a method of manufacturing a plated article using the substrate with a template; and a novel compound. An acid diffusion suppressing agent having a specific structure is blended into the composition including an acid generator which generates acid upon exposure to an irradiated active ray or radiation.

A chemically amplified positive-type photosensitive resin composition capable of suppressing the occurrence of “footing” in which the width of the bottom (the side proximal to the surface of a support) becomes narrower than that of the top (the side proximal to the surface of a resist layer) in the nonresist portion; and the generation of development residue when a resist pattern serving as a template for a plated article is formed on a metal surface of a substrate using the photosensitive resin composition. A mercapto compound having a specific structure is included in the photosensitive resin composition, and includes an acid generator which generates acid upon exposure to an irradiated active ray or radiation, and a resin whose solubility in alkali increases under the action of acid.

A chemically amplified positive-type photosensitive resin composition which is highly sensitive and in which it is easy to form a resist pattern whose cross-sectional shape is rectangular, a photosensitive dry film which includes a photosensitive resin layer formed from the composition, a method of manufacturing the photosensitive dry film, a method of manufacturing a patterned resist film using the composition, a method of manufacturing a substrate with a template using the composition and a method of manufacturing a plated article using the substrate with the template. A Lewis acid compound is included in the composition that also includes an acid generator which generates an acid by application of an active ray or radiation, and a resin whose solubility in alkali is increased by action of an acid.
