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.

Polar silane linkers are provided that attach to resins to form silane-functionalized resins. The functionalized resins can be bound to hydroxyl groups on the surface of silica particles to improve the dispersibility of the silica particles in rubber mixtures. Further disclosed are synthetic routes to provide the silane-functionalized resins, as well as various uses and end products that benefit from the unexpected properties of the silane-functionalized resins. Silane-functionalized resins impart remarkable properties on various rubber compositions, such as tires, belts, hoses, brakes, and the like. Automobile tires incorporating the silane-functionalized resins are shown to possess excellent results in balancing the properties of rolling resistance, tire wear, and wet braking performance.
