Reactive polymeric dyes

Reactive polymeric dyes are provided comprising a chromophoric moiety derived from at least one free radically polymerizable dye and an azlactone moiety derived from 2-alkenylazlactone such that the free radically polymerizable dye is incorporated into the backbone of the polymer. Alternatively, 2-a...

Beschreibung
Zusammenfassung:	Reactive polymeric dyes are provided comprising a chromophoric moiety derived from at least one free radically polymerizable dye and an azlactone moiety derived from 2-alkenylazlactone such that the free radically polymerizable dye is incorporated into the backbone of the polymer. Alternatively, 2-alkenylazlactone is polymerized and then derivatized with a nucleophilic dye or dyes, such that the chromophoric portion of the dye is pendent to the polymer backbone. Both types of reactive polymeric dyes may also contain additional polymerized monomeric units. The reactive polymeric dyes of the present invention can be used in a photoresist system and in particular in a color proofing construction.
