Title:
CURABLE COMPOSITION FOR TRANSPARENT BASE MATERIAL, DRY FILM, CURED MATERIAL, LIGHT-SHIELDING MEMBER AND MEMBER FOR DISPLAY
Document Type and Number:
Japanese Patent JP2020138992
Kind Code:
A
Abstract:
To provide a curable composition for transparent base materials having excellent resolution after development, even when a white pigment such as titanium oxide is added, a dry film, a cured material, a light-shielding member and a member for display.SOLUTION: Provided is a curable composition for transparent base materials, comprising: (A) an alkali-soluble resin that has an ethylenic unsaturated bond equivalent of 1200 or larger, or does not have an ethylenic unsaturated group, (B) a thermosetting component, (C) a photopolymerizable monomer, (D) a white pigment, and (E) an oxime-based photopolymerization initiator. Thus, a cured material formed from the curable resin composition secures, while obtaining a brightness improvement effect due to addition of the (C) white pigment, a high light shielding property and resolution after development. Accordingly, in a transparent substrate, a precise partition pattern can be realized.SELECTED DRAWING: None
