A titanocene-based photoinitiator that absorbs well into the visible range, letting it cure systems that block ordinary UV initiators. The orange solid generates radicals across roughly the violet-to-blue region, so it can drive cure through thick sections and through pigments that screen out shorter wavelengths

Full Description
Unlike the near-UV aminoketones, this metallocene initiator absorbs across the violet and blue-visible region, which is the property that makes it useful where conventional UV photoinitiators stall. That visible-light response lets it cure deeply pigmented films, thick castings and layers behind a substrate, and it is a long-standing choice for color-filter resists, photoimaging and holographic recording media in electronics and display manufacturing. It initiates free-radical polymerization of acrylate monomers and oligomers and is often paired with sensitizers or a second photoinitiator to tune the cure profile. The material is a flammable solid and carries suspected-reproductive-toxicity, repeated-exposure and aquatic classifications; handle per its safety data sheet
