Transparent or translucent sound diffuser-absorbers include a first glass sheet of less than 0.8 mm thickness and a second glass sheet of less than 0.8 mm thickness with a transparent or translucent adhesive layer there between, the adhesive layer adhering the first and second sheets in a fixed configuration such that a first major surface of the first glass sheet has a smooth, repeatedly rising and falling shape. The diffuser-absorbers further include a plurality of through-holes extending through the first glass sheet and through the adhesive layer and through the second glass sheet. Methods of forming are also disclosed.

Tie layers and structures 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 tie layers, when used in a laminate in conjunction with the HOE film, optionally with additional polymer layers, maintain and do not detract from the HOE film properties.

A thermoplastic film 10 is a thermoplastic film comprising a light-emitting layer 11, wherein the light-emitting layer 11 comprises a thermoplastic resin and a light-emitting material that emits light by being irradiated with excitation light, and a change in yellowness of laminated glass obtained by bonding two sheets of clear glass in accordance with JIS R 3211 (1998) having a thickness of 2.5 mm with the thermoplastic film interposed therebetween after conducting a light resistance test for 2000 hours based on JIS R3205 2005 is 4 or less. The present invention provides a thermoplastic film comprising a light-emitting material, in which the emission intensity is unlikely to lower even when the thermoplastic film is exposed to ultraviolet rays for a long period of time.
