Abstract. Twelve magnetic Chemically Peculiar (CP2) stars of the SiSrCrEu subgroup mostly brighter than the 7.5 visual magnitude have been investigated in the infrared at 1.25, 1.6 and 2.2 µ.

Eightysix chemically peculiar stars have been observed in the near infrared with the aim to extend the comprehension of the differences between normal and peculiar stars. These stars have been checked for variability. Most of the stars are previously known light variables, although their periods were not accurate enough to phase together different kinds of observations carried out several years apart. For about 20 stars the period has been refined by combining our own uvby observations with the ones available in the literature.

Abstract17 CP-stars have been measured in the IR filter bands J,H,K,L and M. No significant differences between CP- and normal main sequence stars can be found. Flux exzesses at 4.8 microns are not confirmed.
