Interlayers that exhibit superior properties and that provide desirable optical properties when incorporated into laminates, such as windshields, windows or other glazings containing a holographic optical element (HOE) are disclosed. The interlayers, when used in a laminate in conjunction with the HOE film, maintain and do not detract from the HOE film properties.

Interlayers and encapsulation layers for use with holographic optical elements

Multiple layer interlayers having enhanced optical and acoustic properties are provided, along with methods of making and using the same. Interlayers as described herein may include at least two outer skin layers and an inner core layer, with one of the outer skin layers having a different thickness than the other at one or more locations along the interlayer. The multi-layer interlayer may also exhibit acoustic properties and, in some cases, may have an overall wedged thickness profile. Additionally, in some aspects, interlayers and laminates formed therefrom may also provide reduced infrared energy transmission, without sacrificing acoustic and/or optical performance.

Wedge-shaped multi-layer interlayer with outer skin layers of varying thickness

Resin compositions, layers, and interlayers comprising two or more thermoplastic polymers and at least one RI balancing agent for adjusting the refractive index of at least one of the resins or layers is provided. Such compositions, layers, and interlayers exhibit enhanced optical properties while retaining other properties, such as impact resistance and acoustic performance.

Poly(vinyl acetal) resin compositions, layers, and interlayers having enhanced optical properties

A process for producing a multilayer glass laminate panel having two glass sheets with a poly(vinyl butyral) interlayer sandwiched therebetween, the process comprising the steps of: providing two glass sheets; providing a poly(vinyl butyral) interlayer, and inserting the interlayer between the two glass sheets to produce a laminate; removing air from the produced laminate; applying heat and pressure to the laminate for a hold time, wherein the laminate is free of bubbles at the edges of the laminate. The multilayer glass laminate panel has improved optical properties, and specifically reduced levels of edge defects, such as edge bubbles in the laminate.

Multiple layer panels having reduced levels of edge defects

Resin compositions, layers, and interlayers comprising an acetoacetylized poly(vinyl acetal) resin are provided. Such compositions, layers, and interlayers can exhibit enhanced or optimized properties as compared to non-acetoacetylized poly(vinyl acetal) resins. The acetoacetylized poly(vinyl acetal) resins may be used in a layer or an interlayer for in an architectural application, or the acetoacetylized poly(vinyl acetal) resins may be used in a layer or interlayer, or combined with other layers, to provide an interlayer having good acoustic and other properties.

Esterified poly(vinyl acetal) resin compositions, layers, and interlayers having enhanced properties

An interlayer comprised of a thermoplastic resin, at least one luminescent pigment and a carboxylic acid additive. The use of a thermoplastic resin, at least one luminescent pigment and a carboxylic acid additive reduces or minimizes the optical defects (such as high color or yellowness and increased haze) caused by discoloration of the pigment without sacrificing other characteristics of the interlayer.

Polymer interlayers comprising stabilized fluorescent particles

Resin compositions, layers, and interlayers comprising two or more poly(vinyl acetal) resins and at least one blending agent or haze reducing agent are provided. Such compositions, layers, and interlayers exhibit enhanced optical properties while retaining other properties, such as impact resistance and acoustic performance.

Blends of poly(vinyl acetal) resins for compositions, layers, and interlayers having enhanced optical properties

Multilayered interlayers having good acoustic properties comprising a stiff skin layer(s) and a soft core layer(s) are disclosed. The multilayered interlayers comprise: a first polymer layer (skin layer) comprising plasticized poly(vinyl acetal) resin; a second polymer layer (core layer) comprising plasticized poly(vinyl acetal) resin; wherein at least one plasticizer is a high refractive index plasticizer. The multilayered interlayers have low mottle and resist mottle formation.

Multiple layer interlayer having improved optical and sound insulation properties

The present invention provides multiple layer interlayers having a soft inner polymer layer and relatively stiff outer layers that can be laminated without unacceptable optical distortion and used in various multiple layer glass panel type applications. Multiple layer interlayers of the present invention have surface topography that is formed by controlling the melt fracture that occurs at the exposed surface of the interlayer, or individual layers of the multiple layer interlayer, during formation of the interlayer. By precisely controlling the surface topography of the interlayer, lamination of the interlayer with a rigid substrate does not lead to unacceptable optical distortion caused by the transfer of the surface topography through outer, stiffer layers into softer, internal layers of the interlayer.
