PROBLEM TO BE SOLVED: To provide a resist composition with which fine patterns can be formed without swelling with good practical sensitivity by development using a basic aqueous solution.SOLUTION: A negative type resist composition includes an alkali-soluble resin with an oxetane structure expressed by formulas (I) to (XIII), a solvent and a light acid generator with which acid can be generated with which the oxetane structure of the alkali-soluble resin can react upon absorption and decomposition of an imaging radiation and can be solved in a basic aqueous solution. An exposure part becomes alkali insoluble after exposure of light.

PROBLEM TO BE SOLVED: To provide a photosensitive element having excellent durability for noble metal plating and sufficient release characteristics and preventing a photopolymerizable compound from permeating through a protective film, and to provide a method for forming a resist pattern and a method for producing a lead frame or a printed wiring board using the photosensitive element.SOLUTION: The photosensitive element comprises a support film, a photosensitive resin composition layer formed on the support film, and a polypropylene polymer film. The photosensitive resin composition layer is constituted by a photosensitive resin composition containing (A) a binder polymer, (B) a photopolymerizable compound having at least one polymerizable ethylenically unsaturated bond, and (C) a photopolymerization initiator. The (B) component contains a bisphenol A-based (meth)acrylate compound expressed by general formula (I) and an ethoxylated trimethylolpropane tri(meth)acrylate compound expressed by general formula (II).

PROBLEM TO BE SOLVED: To provide a lithographic printing plate support having excellent scratch resistance, and thereby to provide an original lithographic printing plate which enables a lithographic printing plate formed therefrom to have a long press life and excellent deinking capability when left to stand, and which exhibits excellent on-press developability. SOLUTION: The lithographic printing plate support has an aluminum plate 12 and an anodized aluminum film 14 having micropores 16 which extend in its depth direction from the opposite surface of the aluminum plate 12. Each of the micropores 16 has a large-diameter portion 18 which extends to a depth A of 5 to 60 nm from the surface of the anodized film, has a predetermined mean diameter and a small-diameter portion 20 which communicates with a bottom of the large-diameter portion 18 and extends to a depth of 900 to 2,000 nm from a communication position and has a predetermined mean diameter.

PROBLEM TO BE SOLVED: To provide a method for manufacturing an aluminum substrate for a lithographic printing plate considerably reducing the produced amount of CO 2 leading to global warming by obtaining the aluminum substrate for the lithographic printing plate meeting the quality of aluminum purity and trace metal content with high yield while reducing the amount of by-produced aluminum oxide when recycling the used lithographic printing plate. SOLUTION: The method for manufacturing the aluminum substrate for the lithographic printing plate includes preparing a reclaiming material for the aluminum substrate including the used lithographic printing plate having an image recording layer containing a vinyl copolymer with acrylonitrile as a copolymerization component, on a support body for the lithographic printing plate with roughening treatment and anodization treatment sequentially applied to the aluminum substrate, obtaining reclaimed base metal from the reclaiming material, and adding a required amount of new aluminum base metal and trace metal base alloy containing Cu, to the reclaimed base metal to manufacture a new aluminum substrate.
