    摘要: Laser induced thermal imaging (LITI) donor films, and methods of preparing them, having a substrate, a light-to-heat conversion layer, and a pattern-directing layer. The pattern-directing layer can include patterns of self-assembled monolayer regions, hydrophilic and hydrophobic regions, positively or negatively charged regions, or a series of raised or recessed features. It can also be used to generate charge patterns and magnetic patterns. The pattern-directing layer causes patterning of a transfer layer applied to it, resulting in a templated transfer layer. When imaged, the LITI donor film transfers at least a portion of the templated transfer layer to a permanent receptor while maintaining the pattern substantially intact in the transferred portion.

    摘要: A laser induced thermal imaging (LITI) donor film having a substrate, a light-to-heat conversion layer overlaying the substrate, and a transfer layer overlaying the light-to-heat conversion layer. A surface of the transfer layer includes microstructured or nanostructured features, in a continuous or discontinuous pattern, embossed or otherwise imparted in the transfer layer. The features provide break points to assist in release and transfer of portions of the transfer layer to a permanent receptor in a pattern defined by the features.

    摘要: A guest-host polarizer is disclosed that includes a host matrix, one or more first guest dyes disposed in the host matrix and oriented to absorb a first portion of visible light having a first polarization state, and one or more second guest dyes disposed in the host matrix and oriented to absorb a second portion of visible light having a second polarization state orthogonal to the first polarization state. Such guest-host polarizers can be used in various optical applications and display constructions.

    摘要: Disclosed are thermal transfer elements and processes for patterning organic materials for electronic devices onto patterned substrates. These donor elements and methods are particularly suited for making organic electroluminescent devices and displays. The donor elements can include a substrate, and optional light-to-heat conversion layer, and a single or multicomponent transfer layer that can be imagewise transferred to a receptor to form an organic electroluminescent device, portions thereof, or components therefor, The methods offer advantages over conventional patterning techniques such as photolithography, and make it possible to fabricate new organic electroluminescent device constructions.
