ABSTRACT:
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.
