Claim:
1. A coated flexible substrate comprising a flexible substrate having a coating, wherein the coating includes a) at least two layers of an inorganic material other than silica, each of said layers having a thickness of from 10 to 50 angstroms and being produced by an atomic layer deposition process, and b) a flexibilizing layer interposed between each adjacent pair of layers of the inorganic material, the flexibilizing layer having a total thickness of from 10 to 75% of the thickness of the thicker of said adjacent pair of layers of the inorganic material, wherein the flexibilizing layer is a hybrid organic-inorganic polymer that is deposited by a molecular layer deposition process, wherein the hybrid organic-inorganic polymer is a linear or branched chain structure having metal or semi-metal repeating units which alternate with organic units, the hybrid organic-inorganic polymer having the structure wherein M represents a metal or semi-metal atom selected from, magnesium, calcium, strontium, barium, titanium, zirconium, manganese, iron, nickel, cobalt, zinc, cadmium, aluminum, gallium, indium, germanium, tin, lead, antimony or bismuth, each Z is independently a linking group that contains at least one a heteroatom, R represents a hydrocarbyl or inertly substituted hydrocarbyl group and n represents the degree of polymerization.
