CURABLE COMPOSITION AND SUBSTRATES POSSESSING PROTECTIVE LAYER OBTAINED THEREFROM

摘要

A curable composition which comprises: a) silane-functionalized colloidal
silica; b) at least one curable monomer selected from the group consisting of
aliphatic cyclic acrylate, urethane diacrylate and epoxy resin; and, c) at
least one curing agent for curable monomer (b). The composition when cured
exhibits scratch and abrasion resistant properties making it particularly well-
suited for use as a protective coating for many different kinds of articles,
e.g., CD and DVD discs and especially the more recent Blu-ray Discs, where
these properties are highly desirable and even necessary.
