    We report on time-resolved transmission measurements of a 21.2 nm X-ray laser through thin Al and polyimide foils in the intensity range 1010 - 1012 Wcm-2. Absolute time-integrated and relative time dependent transmission measurements indicate significant differences with cold opacity data, due to the heating, leading to partially ionized states with temperatures of 0.5-20 eV. The transmission data are compared with simulations that qualitatively reproduce the time-dependent ransmission measurements and demonstrate the importance of including detailed tomic absorption processes in the warm dense matter regime.
