    Abstract: The present disclosure provides a printable composition. The printable composition includes a polymer, a polymerizable component, a temporary solvent, a photoinitiator, and optionally an inhibitor. The present disclosure also provides an article including an integral blend of a thermoset polymer and a second polymer different from the thermoset polymer. Further, the present disclosure provides a method of making an article. The method includes (i) providing a printable composition; (ii) selectively curing the printable composition to form a gelled article; and (iii) removing at least a portion of the temporary solvent from the gelled article. The method may optionally include (iv) curing unpolymerized polymerizable component remaining before or after step (iii). Also, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying a plurality of layers of an article, the article including: an integral blend of 8 to 50 wt.%, inclusive, of a thermoset polymer and 30 to 90 wt.%, inclusive, of a second polymer different from the thermoset polymer, wherein the weight percent is based on the total weight of the article; and generating, with the manufacturing device by an additive manufacturing process, the article based on the digital object. A system is provided, including a display that displays a 3D model of an article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of an article.

    Abstract: A planarization tape and a touch sensor assembly including a cover glass, a touch sensor film bonded to the cover glass through an optically clear adhesive layer and the planarization tape releasably bonded to the touch sensor film is described. The planarization tape includes a polymeric substrate and a releasable adhesive layer bonded to the substrate. The substrate has a thickness between 250 micrometers and 5 mm, and the adhesive layer has a thickness between 5 micrometers and 100 micrometers. The adhesive layer may be adapted to releaseably bond to at least one of glass and cyclic olefin polymer film

    Abstract: Article comprising, in order: a first polymeric film having first and second, opposed major surfaces; a first primer layer having first and second opposed, major surfaces on the first major surface of the first polymeric film, wherein for a distance of at least 25 nm starting from the first major surface of the first 5 primer layer toward the second major surface of the first primer layer there is an average Si content, on a theoretical elemental basis, not greater than 15 atomic percent; and a first release layer having first and second opposed, major surfaces, wherein the second major surface of the first release layer is in direct contact with the first major surface of the first primer layer, wherein the first release layer comprises, on a theoretical elemental basis, Si. Articles described herein are useful, for example, as a release liner for 10 casting pressure sensitive adhesives thereon.

    Abstract: Photochromic article having first and second opposed major surfaces comprising a first, transparent layer having first and second opposed major surfaces, the first layer comprising thermoplastic, a second, transparent layer having first and second opposed major surfaces, the second layer comprising photochromic dye and amorphous copolyester, wherein the first major surface of the second layer is adjacent to the second major surface of the first layer, and a third layer having first and second opposed major surfaces, wherein the first major surface of the third layer is adjacent to the second major surface of the second layer. Embodiments of photochromic article described herein are useful, for example in eyewear, window films, security films, decorative films, electronic devices (i.e., having a display with a photochromic article).
