US Patent:

6410173, Jun 25, 2002

Filed:

Nov 30, 1998

Appl. No.:

09/201599

Inventors:

Nanning J. Arfsten - Moorestown NJ
Axel Reich - Moorestown NJ
Frank Rodriguez - Maple Shade NJ
James F. Gavlas - Mercerville NJ

Assignee:

Denglas Technologies, LLC - Moorestown NJ

International Classification:

B32B 900

US Classification:

428701, 428702, 428697, 428699, 428428, 428432, 428216, 428212, 351166

Abstract:

The invention includes a bilayer antireflection coating, multilayer antireflection coatings, and a method for making a multilayer antireflective coated substrate. The bilayer and multilayer coatings include layers having metallic oxides, at least one layer in each of such coatings having as a material with an index of refraction at least about 1. 90, a layer comprising oxides of zirconium such that when subjected to heat treatments, such as tempering, the coatings substantially retain their optical properties. The coatings further include layers having materials of low index of refraction which include oxides of aluminum which provide coating stability and increased coating solution storage life. In the method, the layers are applied by successive dip coating techniques using solvent-based solutions and the resulting coatings can be used to coat large sized substrates which can be later cut, trimmed and/or otherwise shaped and later heat treated with substantial retention of optical properties.
