OPTICAL ARTICLE FOR SECONDARY PROCESSING AND ITS SECONDARY PROCESSED OPTICAL ARTICLE

摘要

PPROBLEM TO BE SOLVED: To provide an optical article for secondary processing, and to provide a secondary processed optical article prepared by heating and bending the optical article. PSOLUTION: This optical article for secondary processing, among whose longitudinal, lateral and height lengths the minimum length is ≥5 mm, and which is prepared by melt-molding a composition comprising a methacrylic resin (B) and acrylic multi-layered structure polymer particles (A) in which a layer constitution, the mol.wt. and average particle diameter of a methacrylic resin component constituting the outermost layer, and the (co)polymer composition and refractive index of each layer are controlled. And a secondary processed optical article prepared by heating and bending the optical article. PCOPYRIGHT: (C)2007,JPO&INPIT
