Some CP stars have recently been discovered by Catalano et al. to
be variable also in the near infrared, although with smaller amplitudes
than in the visible. Hence an observational campaign was started in
which the infrared light variability of a number of CP2 and CP4 stars
has been investigated at the ESO-La Silla Observatory in the bands J,
H, and K. As a general result, infrared variations show the same
behavior in all three filters but amplitudes are smaller than in the visible.
