A multilayer article including a film layer having a textured first surface and an opposite second surface, wherein the film layer is printable, and a nonwoven material layer bonded to the second surface of the film layer. The film layer may include a semi-crystalline polylactic acid and may be receptive to inkjet printing.

The present disclosure relates to micro-optical assemblies containing at least one optical element adhered to a receptor substrate, e.g. a transparent receptor substrate, the receptor substrate contains at least one graphics layer. The micro-optical assemblies include both functional micro-optical structures that can alter, for example, incident light, and a graphic layer, which includes at least one graphic, e.g. a graphic design, which may include color, patterns, imagery, indicia and the like. The combination of the micro-optical elements with the graphic of the graphics layer can provide unique light altering assemblies that have graphic designs that may be functional, e.g. to display a message, and/or have aesthetic value. The micro-optical assemblies of the present disclosure are useful in a variety of applications which include, but are not limited to, display and graphics applications and architectural glass applications. The present disclosure also provides a method of making the micro-optical assemblies of the present disclosure.

The disclosed light directing article comprises a structured layer, an adhesive sealing layer, and barrier elements. The structured layer comprises multiple microstructured elements that are opposite a major surface. The adhesive sealing layer has a first region and a second region. The second region is in contact with the structured layer. The barrier element are at the first region. The first region with the barrier element and second region have sufficiently different properties to form a low refractive index layer between the adhesive sealing layer and the structured layer. The barrier element comprises a crosslinked polymeric matrix having a modulus of elasticity less than 4.4 GPa.

The present disclosure relates to transfer tapes, segmented and non-segmented which include at least one graphics layer. The transfer tapes include a removable template layer, a transfer layer which includes a backfill layer, having at least one first graphics layer, and an adhesive layer. Segmented transfer tapes further at least one transferable segment, at least one non-transferable segment in the segmented transfer tape and include at least one kerf. The present disclosure also provides optical assemblies, e.g. micro-optical assemblies, which may be fabricated from the transfer tapes which include at least one graphics layer. The present disclosure also provides methods of forming the transfer tapes and methods of making the micro optical assemblies.

Segmented and non-segmented transfer tapes, articles therefrom and method of making and use thereof

The present disclosure relates to segmented transfer tapes useful in the transfer of only a portion of the segments of the transfer tapes and methods of making thereof. The segmented transfer tapes include a removable template layer having a structured surface; a transfer layer comprising a backfill layer, wherein the backfill layer has a structured first major surface, and an adhesive layer; at least one transferable segment formed in the transfer layer; at least one non-transferable segment formed in the transfer layer, the at least one non-transferable segment includes an adhesive surface, wherein a passivating layer is disposed on at least a portion of the adhesive surface of the at least one non-transferrable segment; and at least one kerf extending from the first major surface of the adhesive layer and into at least a portion of the removable template layer. The present disclosure also provides micro-optical assemblies and methods of making micro-optical assemblies from the segmented transfer tapes.
