Abstract
A process, system, and materials for lamination of anti-reflective glass to the screen of a CRT display, including a polymerizable adhesive and laminated articles are described. The photopolymerizable adhesive composition including, in certain embodiments, an epoxy resin and a photosensitive initiating system are disclosed.
Claims18
A laminated article, the article comprising:
- a first rigid substrate and a second rigid substrate;
- and
- a photocurable adhesive composition applied between the first and second substrates, the adhesive including:
- (a) at least one epoxy resin, and
- (b) a photosensitive initiating system activatable by light transmitted through at least one of the substrates, said substrate having less than 25 percent transmission of light at a wavelength of 330 nm;
- wherein the photocurable adhesive composition has a Brookfield viscosity at 25° C. of less than 500 centipoise prior to application, and a refractive index after curing within 0.01 of at least one of the first and second rigid substrates.
