Optical structures

An optical structure comprising:

• a substrate;
• and
• a plurality of two-sided optical components, each side of each component having optical microstructures, the components being disposed along the substrate, wherein at least a portion of one side of at least some of the components is air-backed and the other side of the at least some of the components is substantially wetted-out by a material of the substrate, the substrate includes at least one adhesive selected from a group consisting of a substantially transparent heat-activated or substantially transparent pressure-sensitive adhesive, wherein at least some of the two-sided optical components are partially embedded within the adhesive to substantially wet-out one side of at least some of the components, the other side of the at least some of the components being air-backed.

An optical structure comprising:

• a substrate;
• and
• a plurality of two-sided optical components, each side of each component having optical microstructures, the components being disposed along the substrate, wherein at least a portion of one side of at least some of the components is air-backed and the other side of the at least some of the components is substantially wetted-out by a material of the substrate, the substrate includes at least one adhesive selected from a group consisting of a substantially transparent heat-activated or substantially transparent pressure-sensitive adhesive, wherein the adhesive has the same index of refraction as material that forms the plurality of two-sided components.

An optical structure comprising:

• a substrate;
• and
• a plurality of two-sided optical components, each side of each component having optical microstructures, the components being disposed along the substrate, wherein at least a portion of one side of at least some of the components is air-backed and the other side of the at least some of the components is substantially wetted-out by a material of the substrate and wherein the substrate includes a liquid-curable coating.

A method for forming an optical structure comprising:

• providing a substrate;
• and
• providing a plurality of two-sided optical components alone the substrate, wherein at least one side of substantially all of the components is air-backed and the other side of substantially all of the components is substantially wetted-out, wherein the components include cube- corner prisms and wherein the substrate is a first substrate, further comprising providing the cube-corner prisms along a plurality of second substrates.
