Context :

Aims : The 0.5-150 keV broad-band spectra of a sample of nine bright type 1 Seyfert galaxies are analyzed here .
These sources have been discovered/detected by INTEGRAL and subsequently observed with XMM–Newton for the first time with high sensitivity below 10 keV .
The sample , although small , is representative of the population of type 1 AGN which are now being observed above 20 keV .

Methods : The intrinsic continuum has been modeled using three different parameterizations : a power-law model , an exponential cut-off power-law and an exponential cut-off power-law with a Compton reflection component .
In each model the presence of intrinsic absorption , a soft component and emission line reprocessing features has also been tested .

Results : A simple power-law model is a statistically good description of most of the spectra presented here ; an FeK line , fully and/or partial covering absorption and a soft spectral component are detected in the majority of the sample sources .
The average photon index ( < \Gamma > = 1.7 \pm 0.2 ) is consistent , within errors , with the canonical spectral slope often observed in AGN although the photon index distribution peaks in our case at flat \Gamma ( \sim 1.5 ) values .
For four sources , we find a significantly improved fit when the power-law is exponentially cut-off at an energy which is constrained to be below \sim 150 keV .
The Compton reflection parameter could be estimated in only two objects of the sample and in both cases is found to be R > 1 .
