Abstract
Provided is a benzotriazole compound that efficiently absorbs ray having a long wavelength of 360-400 nm, i) having excellent solubility in a monomer of a resin raw material, being dissolvable at a high concentration, polymerizing at excellent reactivity, and yielding a high-molecular-weight resin member and a transparent resin member, or ii) having exceptional heat resistance. This benzotriazole compound is represented by formula (I), where at least one of R-Ris represented by formula (i-1), (where Rand R11 are hydrocarbon groups, etc., and Ris represented by formula (i-2) or formula (i-3) (in formula (i-2), Arepresents a divalent group selected from nitrogen-Containing groups, oxygen-containing groups, sulfur-containing groups, phosphorus-containing groups, and phenylene groups, and R-Rand X represent hydrocarbon groups, etc.; and in formula (i-3), Arepresents a divalent group selected from nitrogen-containing groups, oxygen-containing groups, sulfur-containing groups, and phosphorus-containing groups, and Xand Xrepresent hydrocarbon groups, etc.)).
