Abstract

The invention provides a black curable resin composition. A black cured substance with excellent flexibility and high transmittance with respect to the light of ultraviolet ray region wavelength can be obtained. The black curable resin composition comprises (A) photosensitive resin containing carboxyl, (B) photopolymerization initiator, (C) dilluent, (D) epoxy compound, (E) polyurethane (meta) acrylic ester, and (F) perylene black colorant.

Description

technical field [0001] The present invention relates to a black curable resin composition capable of obtaining a cured product excellent in flexibility. For example, it relates to a black curable resin composition capable of forming a flexible Excellent black curable resin composition for curing coating films. Background technique [0002] A printed circuit wiring board is used to form a conductive circuit pattern on a substrate and mount electronic components on the land of the pattern by soldering. Except for the soldering land, the printed circuit wiring board is used The other circuit parts are covered with a solder resist film as a permanent protective film. Thus, when soldering electronic parts on a printed circuit board, it is possible to prevent solder from adhering to unnecessary parts, and to prevent circuit conductors from being directly exposed to the air and being corroded due to oxidation and humidity. [0003] In addition, in recent years, solder resist film...
