Provided is a thermoplastic resin composition or the like which can suppress changes in transmittance, particularly changes in transmittance in a short-wavelength region, even if an additive or the like is added. The above-mentioned problem is solved by a thermoplastic resin composition for an optical material, which contains a compounding agent represented by general formula (1). (In general formula (1), R1-R5 each independently represent a hydrogen atom or an optionally substituted alkyl group having 1-20 carbon atoms in total, R6-R9 each independently represent a hydrogen atom or an optionally substituted alkyl group having 1-20 carbon atoms in total, and R10 represents a hydrogen atom or an optionally substituted alkyl group having 1-5 carbon atoms in total. ) 本发明提供即使添加添加剂等也能够抑制透射率的变化，特别是能够抑制短波长区域的透射率变化的热塑性树脂组合物等。上述技术问题通过含有以下通式(1)所示配合剂的用于光学材料的热塑性树脂组合物解决。(通式(1)中，R1～R5分别独立地表示氢原子或可以具有取代基的合计碳原子数1～20的烷基，R6～R9分别独立地表示氢原子、可以具有取代基的合计碳原子数1～20的烷基，R10表示氢原子或合计碳原子数1～5的烷基。)
