Compounds useful as surface coating agents, including compounds of the formula:wherein X1 comprises a first photoreactive species; X2 comprises a second photoreactive species; Y comprises a nonpolymeric core molecule comprising an aromatic group; and Z comprises at least one charged group. The Y core can include an aromatic group such as a benzene radical, the charged groups Z can be independently selected from the organic acids that include sulfonic acid, carboxylic acid, and phosphoric acid, and the photoreactive species of X1 and X2 can independently be aryl ketones, such as those selected from the group acetophenone, benzophenonie, anthraquinone, anthrone, and anthrone-like heterocycles, and their substituted derivatives. Examples of such coating agents include 4,5-bis(4-benzoylphenylmethyleneoxy) benzene-1,3-disulfonic acid di(potassium and/or sodium) salt, 2,5-bis(4-benzoylphenylmethyleneoxy)benzene-1,4-disulfonic acid di(potassium and/or sodium) salt (Compound II), and 2,5-bis(4-benzoylphenylmethyleneoxy)benzene-1-sulfonic acid monopotassium and/or monosodium salt.
