感光性樹脂組成物、感光性樹脂組成物が塗工されたドライフィルム及び感光性樹脂組成物の光硬化膜を有するプリント配線板
Document Type and Number:
Japanese Patent JP6596550
Kind Code:
B2
Abstract:
To provide: a photosensitive resin composition capable of obtaining a cured coating film having a superior line shape for preventing undercut and excellent elongation characteristics without impairing basic characteristics such as dry-to-touch property; a dry film coated with the photosensitive resin composition; and a printed wiring board having a photocured film of the photosensitive resin composition.SOLUTION: There is provided a photosensitive resin composition which comprises (A) a carboxyl group-containing photosensitive resin obtained by adding e) a polybasic acid and/or a polybasic acid anhydride to an unsaturated carboxylated epoxy resin which is a reaction product of a) an epoxy resin having two or more epoxy groups in one molecule, b) at least one saturated monocarboxylic acid having 5 to 17 carbon atoms, c) a dicarboxylic acid and d) an ethylenically unsaturated group-containing carboxylic acid and (B) a photopolymerization initiator.SELECTED DRAWING: None
