BLACK RESIN COMPOSITION FOR LIGHT BLOCKING FILMS, SUBSTRATE WITH LIGHT BLOCKING FILM OBTAINED BY CURING COMPOSITION, COLOR FILTER HAVING SUBSTRATE WITH LIGHT BLOCKING FILM, AND TOUCH PANEL

To provide a black resin composition for light blocking films which is used to obtain a black hardened film (light blocking film) that produces a reflection color of an achromatic or achromatic to bluish black hue, and to provide a transparent substrate with the light blocking film formed thereon.SOLUTION: A black resin composition for light blocking films contains essential ingredients of (A) a light- or heat-curable resin and/or light- or heat-curable monomer, (B) a black light blocking particle-containing dispersion liquid comprising black light-blocking particles dispersed in a dispersion medium, and (C) a color adjustment particle-containing dispersion liquid comprising color adjustment particles dispersed in a dispersion medium. The black resin composition is characterized in that: a ratio DC/DB of an average secondary particle diameter DC of the color adjustment particles in the ingredient (C) to an average secondary particle diameter DB of the black light-blocking particles in the ingredient (B) is in a range of 0.2 to 1.2; and a ratio mC/mB of a mass mC of the color adjustment particles in the ingredient (C) to a mass mB of the black light-blocking particles in the ingredient (B) is in a range of 0.03 to 0.2.SELECTED DRAWING: None 【課題】反射色が無彩色又は無彩色から青味を帯びた黒色の色相を有する黒色硬化膜（遮光膜）を得るための遮光膜用黒色樹脂組成物、及びこの遮光膜が透明基板上に形成された遮光膜付透明基板を提供する。【解決手段】（A）光若しくは熱による硬化性樹脂、及び／又は光若しくは熱による硬化性単量体、（B）分散媒中に黒色遮光性粒子が分散されてなる黒色遮光性粒子含有分散液、及び（C）分散媒中に色調整用粒子が分散されてなる色調整用粒子含有分散液を必須成分とし、（C）成分中の色調整用粒子の平均二次粒子径ＤＣと、（B）成分中の黒色遮光性粒子の平均二次粒子径ＤＢとの比ＤＣ／ＤＢが0.2〜1.2の範囲であり、且つ（C）成分に含まれる色調整用粒子の質量ｍＣと、（B）成分に含まれる黒色遮光性粒子の質量ｍＢとの比ｍＣ／ｍＢが0.03〜0.2の範囲であることを特徴とする遮光膜用黒色樹脂組成物である。【選択図】なし
