Abstract:	Near-infrared imaging of ten nearby ULIRGs with known redshifts has shown that at 0.5 arcsec resolution the nuclei have very red colors which cannot in general be reproduced by reddening stellar light, but require an additional component of hot dust emission. Up to about 50% of the nuclear K-band continuum originates in hot dust, although the temperature cannot be determined by JHK colors alone. Comparison with optical emission-line classifications (where known) suggests that there may be a correlation with activity type; that is, Seyfert 2s have more K-band dust emission than LINERs, and LINERs more than starbursts.
