Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: 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 D/Dof an average secondary particle diameter Dof the color adjustment 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 1.2; and a ratio m/mof a mass mof the color adjustment particles in the ingredient (C) to a mass mof the black light-blocking particles in the ingredient (B) is in a range of 0.03 to 0.2.SELECTED DRAWING: None
