Abrasion resistant, tintable coating compositions which are based on siloxane/silica hybrid coating resins and which also contain at least about 3 percent but less than about 20 percent of a tintability enhancing compound selected from the group consisting of polyhydroxyl-functional compounds and butylated urea formaldehyde compounds. These coating compositions are especially useful for providing both abrasion resistance and high levels of tinting and, optionally, absorbance of ultraviolet radiation. Tetrahydroxybenzophenone is a preferred tintability enhancing compound that also absorbs UV light.
