COMPOSITION FOR OPTICAL DISK PROTECTION FILM

摘要

The present invention provides compositions for protective films for optical discs having a low viscosity and a low risk of substrate erosion without spoilage of scratch resistance. The compositions for protective films for optical discs of the present invention comprise inorganic microparticles dispersed in an acrylic radical-based binder resin. The binder resin is formed from a binder monomer comprising a base component, a scratch-resistant component and a diluent component. The diluent components include diluent monomers having principal chain structures including a functional group having a cyclic structure or a branched carbon chain structure. A monomer having a monofunctional or bifunctional group can be used as the diluent component.
