PROBLEM TO BE SOLVED: To provide a black resin composition for light blocking films which is used to obtain a light blocking film that offers reduced reflectance, and to provide a 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 transparent particle-containing dispersion liquid comprising transparent particles dispersed in a dispersion medium. The black resin composition is characterized in that: a ratio D/Dof an average secondary particle diameter Dof the transparent particles in the ingredient (C) to an average secondary particle diameter Dof the black light-blocking particles in the ingredient (B) is in a range of 0.2 to 1.0; a ratio m/mof a mass mof the transparent particles in the ingredient (C) to a mass mof the black light-blocking particles in the ingredient (B) is in a range of 0.015 to 0.20; and the transparent particles have a refractive index that is no greater than that of a hardened product of the ingredient (A).SELECTED DRAWING: None 【課題】反射率を低減させることができる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、並びに（C）透明粒子を分散媒中に分散されてなる透明粒子含有分散液を必須成分とし、（C）成分中の透明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0.2〜1.0の範囲であり、且つ（C）成分中の透明粒子の質量ｍＣと、（B）成分の黒色遮光性粒子の質量ｍＢとの質量比ｍＣ／ｍＢが0.015〜0.20の範囲であり、また、前記透明粒子の屈折率が、前記(A)成分の硬化物の屈折率以下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
