COLORING COMPOSITION, CURED FILM, LIGHT SHIELDING FILM, COLOR FILTER, OPTICAL ELEMENT, SOLID-STATE IMAGING ELEMENT, INFRARED SENSOR, AND HEADLIGHT UNIT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18450368 titled 'COLORING COMPOSITION, CURED FILM, LIGHT SHIELDING FILM, COLOR FILTER, OPTICAL ELEMENT, SOLID-STATE IMAGING ELEMENT, INFRARED SENSOR, AND HEADLIGHT UNIT
Simplified Explanation
The patent application describes a coloring composition that can create a cured film with vibrant color and strong adhesion to a base material. It also discusses various applications of this composition, such as in light shielding films, color filters, optical elements, solid-state imaging elements, infrared sensors, and headlight units.
- The coloring composition contains a pigment, a solvent, and a resin with specific chemical units.
- The resin has a polymerizable group (unit A), a phenolic hydroxyl group (unit B), and an acidic group (unit C).
- The pigment content in the composition is at least 15% by mass of the total solid content.
- The cured film formed using this composition has a high color value and excellent adhesiveness to the base material.
- The composition can be used to create light shielding films, color filters, optical elements, solid-state imaging elements, infrared sensors, and headlight units.
Original Abstract Submitted
There are provided a coloring composition, which makes it possible to form a cured film having a high color value and excellent adhesiveness to a base material, and provided a cured film, a light shielding film, a color filter, an optical element, a solid-state imaging element, an infrared sensor, and a headlight unit. The coloring composition according to the present invention contains a pigment, a solvent, and a resin having a constitutional unit A having a polymerizable group, a constitutional unit B having a phenolic hydroxyl group, and a constitutional unit C having an acidic group, where a content of the pigment is 15% by mass or more with respect to a total solid content.
