Provided are a silane-phenol compound, a crosslinked silxoane-phenolic protective overcoat layer thereof, and an electrophotographic imaging member such as photoreceptor. The silane-phenol compound comprises (i) a phenol group and (ii) a silane group selected from the group consisting of alkoxysilyl, arylalkoxysilyl, aryloxysilyl, alkylaryloxysilyl, and combination thereof. The silicone overcoat is made from a formulation comprising the silane-phenol compound and a hydroxymethylated hole transport compound. The crosslinked siloxane-phenolic overcoat may be used to manufacture an electrophotographic imaging member such as photoreceptor with improved properties such as abrasive resistance, good image quality and cleanability, etc.
