3results about How to "Initiation efficiency is high" patented technology

The raw material compositions for preparing acrylic optical coatings and for preparing acrylic optical lenses both contain sulfur-containing aromatic acrylate compounds as shown in Formula A. The optical materials prepared from these raw material compositions, with precisely controlled refractive indices of 1.53–1.60, significantly improve the material's resistance to yellowing, optical durability, and impact resistance, meeting the application requirements of high-end optical materials. Wherein, R1 = CH2 = CH-COO, R2 = CH3, n = 2 or 3, and m = 0, 1, or 2.

The application discloses a cycloalkane oxime ester photoinitiator and a preparation method and application thereof, and belongs to the field of chemical synthesis and photocuring technology. The photoinitiator has a structure as shown in the formula (I).

The invention provides a bis-carbazolyl sulfonium salt-containing compound as well as a preparation method and application thereof, and belongs to the technical field of photochemistry. The bis-carbazolyl sulfonium salt-containing compound provided by the invention has a structure as shown in a formula (I). According to the invention, the molecular volume is increased by introducing the dicarbazole group, and meanwhile, the compound has very excellent solubility and photosensitive activity, and can be used as a high-quality substitute of a resist acid generator and a photoinitiator for cationic polymerization.
