PROBLEM TO BE SOLVED: To provide an optical article for secondary processing and a secondary processed optical article obtained by heating and bending the optical article. SOLUTION: Acrylic multilayer structure polymer particles (A) and methacrylic resins in which layer structure, molecular weight of methacrylic resin component constituting outermost layer, average particle diameter, (co) polymer composition and refractive index of each layer are controlled. An optical article for secondary processing having a minimum length of 5 mm or more in length, width, and height, obtained by melt-molding a composition comprising (B), and heat bending the optical article Secondary processed optical article.
