  The brightest persistent Galactic black hole candidate close to the Galactic
Centre, 1E 1740.7-2942, has long been observed with INTEGRAL. In this paper, we
report on the long-term hard X-ray monitoring obtained during the first year of
observations as part of the Galactic Centre Deep Exposure. We discuss the
temporal and spectral behaviours in different energy bands up to 250 keV, as
well as the hardness-flux correlations.
