A release of multicolor broadband (BVRI) photometry for a subsample of 44 isolated spirals drawn from the Catalogue of Isolated Galaxies is presented. Total magnitudes and colors at various circular apertures, as well as some global structural/morphological parameters, are estimated. Morphology is reevaluated through optical and sharp-filtered R-band images, (B-I) color index maps, and archived near-IR JHK images from the Two Micron All Sky Survey. The CAS structural parameters (concentration, asymmetry, and clumpiness) were calculated from the images in each of the bands. The fraction of galaxies with well-identified optical/near-IR bars (SB) is 63%, while another 17% show evidence of weak or suspected bars (SAB). The sample average value of the maximum bar ellipticity is ε_max~0.4. Half of the galaxies in the sample show rings. We identify two candidates for isolated galaxies with disturbed morphology. The structural CAS parameters change with the observed band, and the tendencies they follow with morphological type and global color are more evident in the redder bands. In any band, the major difference between our isolated spirals and a sample of interacting spirals is revealed in the A-S plane. A deep and uniformly observed sample of isolated galaxies is intended for various purposes, including (1) comparative studies of environmental effects, (2) comparing model predictions of galaxy evolution, and (3) evaluating the change of galaxy properties with redshift.
