Multilayer articles via wet-on-wet processing

A method comprising:

• moving, along a web path, a substrate from a first coating applicator to a second coating applicator, the substrate comprising a structured surface including a pattern of structured features;
• applying a first coating fluid from the first coating applicator on to the structured surface of the substrate to form a first coating layer directly over the pattern of structured features, wherein the first coating fluid comprises a first polymer having a Fox Tg of −20 to 50° C.;
• applying a second coating fluid from the second coating applicator on to the first coating layer to form a second coating layer directly over the first coating layer, the second coating fluid being different from the first coating fluid, wherein the second coating fluid comprises a second polymer having a Fox Tg of up to −30° C.;
• and
• solidifying the first and second coating layers to form a dual-layer coating comprising a skin layer and a bulk layer,
• wherein a residence time between applying the first coating fluid and applying the second coating fluid is controlled to achieve a diffuse interface having a thickness of 0.2 to 5.0 micrometers between the skin layer and the bulk layer, the diffuse interface comprising sub-micron domains of the second polymer encapsulated within the first polymer.
