A multilayer film having a backing with an integrally formed polymeric liner, made in a common coextrusion process. The polymeric liner has material properties deemed to make it incompatible with the backing material, resulting in two layers that resist separation during manufacture and transportation but are hand separable in field applications and installation.

Multilayer film with integrally formed liner

Uncured aqueous composition comprising surfactant and a blend of (a) a first sulfonated polyester having a glass transition temperature not greater than 75° C. that is not sulfonated polyethylene naphthalate, (b) a second, sulfonated polyester that is a sulfonated polyethylene naphthalate, (c) melamine-formaldehyde crosslinker, and (d) an epoxy silane coupling agent; and cured composition thereof. Compositions described herein are useful, for example, for making primed film for release liners applications.

Composition and article comprising the same

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).

Photochromic articles

A substrate including a self-supporting tri-layer stack is described. The tri-layer stack includes first and second outer layers and a biaxially oriented layer disposed between and in direct contact with the first and second outer layers. The biaxially oriented layer may include a first polyester having greater than 45 mole percent naphthalate units and greater than 45 mole percent ethylene units. Each of the first and second outer layers includes a second polyester which may include 40 to 50 mole percent naphthalate units, at least 25 mole percent ethylene units, and 10 to 25 mole percent of branched or cyclic C4-C10 alkyl units.
