Scientific paper

Near infrared photometry (in J, H, and K) is presented for twelve WC5-7 and WN7-8 southern Wolf-Rayet stars. Corrections are made for the influence of emission lines and the effects of interstellar extinction; the corrections for WC5 and WC6 stars are 0.15-0.09 mag, while the WN5 star correction is 0.07 mag. Reddening and infrared colors are discussed, and it is suggested that the intrinsic (b-v)0 of the WC5-7 is about 0.15 mag bluer than previously thought. An intermediate sequence WN6-C7 star has colors similar to those of the WN stars.
