Narrative:
At 13;000 ft EICAS reported an anti-ice duct master warning and master caution. Checklist actions required securing the anti-ice system and exiting icing conditions. Once secured; the messages extinguished. Light rime was accreting and lower altitudes promptly provided by ARTCC did not provide an exit from the conditions. An emergency was then declared with ARTCC and the flight proceeded direct to a nearby airport without incident; remaining in icing conditions until landing. Due to current meteorological conditions and aircraft position and configuration; the chosen airport was the most suitable airport to land.
