PURPOSE:To obtain the subject film which is very thin and excellent in scratch resistance by forming a monomolecular film or a built-up film by causing molecules having linear organosiloxane backbones to be chemically adsorbed in an oriented state to the surface of a substrate. CONSTITUTION:A substance having one chlorosilyl group at the molecular terminal, (e.g. CH3-[Si(CH3)2O]6-SiCl3 or Cl-[Si(CH3)2O]7SiCl3) is dissolved in a concn. of about 4wt.% into a nona medium to give a chemical adsorbent. When a well-dried hydrophilic substrate 1 is immersed in the adsorbent for about 2hr, the dehydrochlorination between SiCl groups of the adsorbent and hydroxyl groups on the surface of the substrate 1 having many hydroxy groups 2 occurs. Then, the surface is washed well with an org. solvent to remove an excess surfactant remaining on the surface and washed with water, thus giving a monomolecular organosiloxane film 3 chemically bonded to the surface in a thickness of about 20Angstrom .
