Optical products are disclosed that include a polymer substrate; a composite coating, deposited on the polymer substrate; a permeating adhesive, which permeates the composite coating and is in contact with the polymer substrate; and a protective layer, secured to the composite coating by the permeating adhesive. The composite coating includes at least a first layer and a second layer, each of which is provided with a binding group component which together form a complementary binding group pair. The optical products exhibit improved resistance to delamination during storage and use.

Laminated optical products and methods of making them

A method for laminating glass, a laminate assembly, and an adhesive-coated plastic material used in a laminate assembly. Specifically an adhesive, once applied to a plastic layer is grooved or textured to allow formerly trapped air to escape from between layers of a laminate assembly during a laminate process. This can allow for the adhesive layer to be thinner, while still providing for a final product that is relatively air bubble-free and optically pleasing or substantially free of optical defects caused by waviness of the plastic layer between two PVB sheets and/or wrinkles of the plastic sheet.

Glass laminate using textured adhesive

A low-e insulating glass unit has a suspended, coated IR reflecting polymer sheet under tension, e.g. from heat shrinkage. The polymer sheet is coated with a multilayer stack of dielectric and metallic layers, including at least one silver layer deposited upon a zinc oxide seed layer that is at most 15 nm thickness. The use of zinc oxide ensures good seeding for high quality silver layer growth, thereby providing low emissivity. The thinness of the zinc oxide ensures that it resists cracking when the polymer sheet is tensioned.

'Corrosion' performance of an optical filter is enhanced when a relatively thick zinc-based film functions as a seed layer for a subsequently formed silver-based film. At least two pairs of dielectric and metallic layers are included within the optical filter, where the zinc-based film is a second film of the dielectric layer and where the silver-based film is the metallic layer. The zinc-based film has a zinc content of at least 80 percent and has a thickness of at least 15 nm. In order to further improve the corrosion performance, gold may be incorporated into the silver-based film.

Robust optical filter utilizing pairs of dielectric and metallic layers

In a method of forming micro traces, stamping techniques are employed to define a target pattern of the micro traces. The stamping is applied to electrically conductive material and may be limited to pressure, but a thermal stamping approach may be utilized. Following the stamping, a portion of the conductive material is removed, leaving the target pattern of conductive micro traces. In the pressure-application step, the pressure or the combination of pressure and temperature is sufficient to at least weaken the integrity of the bulk conductive material along the area of contact. Typically, this step causes shearing of the conductive material. Following the pressure-application step, excess conductive material is removed. In some embodiments of the invention, the thickness of the micro traces is not determined in a single step. The original thickness may be formed using a 'seed' material. The subsequent material buildup may occur after the target pattern is established.

Fabrication of conductive micro traces using a deform and selective removal process

An optical arrangement includes a transmissive or reflective substrate having a first surface on which a multi-layer antireflection stack is formed. The antireflection stack is protected by a fluorocarbon lubricating layer that reduces the surface energy of the exposed surface to less than 40 dynes/cm, and preferably less than 20 dynes/cm. The fluorocarbon lubricating layer and a silane adhesion promotion layer form a durable topcoat having desired mechanical and optical characteristics. The preferred material for forming the lubricating layer is a fluoropolymer sold by 3M Company under the federally registered trademark FLUORAD.

Multi-layer topcoat for an optical member

An improved way to impart antireflection properties to light transmissive substrates and, at the same time, achieve a durable surface and electrical conductivity is disclosed. A stack of at least two sputter-deposited light transmissive inorganic layers, one of which being electrically conductive and having a high index of refraction with the one above it (relative to the substrate being antireflected) having a low index of refraction, in combination with a thin lubricating overlayer comprising a solvent-soluble lubricant such as a solvent-soluble fluoropolymer can achieve this desired combination of properties.
