Abstract
The present invention provides compositions derived from a polycarboxylic acid, a polyhydroxy compound, a dye and a basic crosslinking agent. The compositions can be used to prepare cross-linked films that exhibit low solvent-swell characteristics. The cross-linked films can be used to prepare color filter elements via thermal transfer processes.
