BLACK RESIN FILM, CAPACITANCE TYPE INPUT DEVICE, METHOD FOR PRODUCING THEM, AND IMAGE DISPLAY APPARATUS USING THE SAME

摘要

A black resin film is produced by applying a photosensitive resin composition containing a black pigment, an alkali-soluble polymer compound, an ethylenic unsaturated bond-containing compound and α-aminoalkylphenone or α-hydroxyalkylphenone as a photopolymerization initiator, to a substrate; and subjecting the composition to exposure, development and post-exposure. The post-exposure is performed from both side with 1,300 mJ/cm2 or more in terms of i line.

1. A method for producing a black resin film, comprising:
applying a photosensitive resin composition containing a black pigment, an alkali-soluble polymer compound, an ethylenic unsaturated bond-containing compound and a photopolymerization initiator, to a substrate, exposing the photosensitive resin composition on the substrate, developing the photosensitive resin composition thus exposed, and subjecting the developed composition to post-exposure, and wherein the following condition (A) or the following condition (B) are satisfied: Condition (A): the photopolymerization initiator is an α-aminoalkylphenone compound or an α-hydroxyalkylphenone compound, and Condition (B): the post-exposure after the development is performed from both a surface of the photosensitive composition on a side that is in contact with the substrate and a surface thereof on a side that is not in contact with the substrate, and wherein an exposure amount in the post-exposure after the development is 1,300 mJ/cm2 or more in terms of i line.
