Profiles of surface brightness, ellipticity and position angle obtained from CCD-BVRI images are presented for a sample of 14 spiral galaxies with 13<B_T<16.1. For these galaxies, exponential disc components were fitted to the profiles. A decrease of disc scalelengths from B to I is found for 13 galaxies, while for one galaxy scalelengths increase from B to I. The scalelength ratios r_D(B)/r_D(I), r_D(V)/r_D(I) and r_D(R)/r_D(I) show a systematic increase with increasing apparent ellipticity. The maximum variation is found for r_D(B)/r_D(I) which is 80 % larger for edge-on galaxies than for face-on galaxies.
