R ″ is hydrogen or C _1-4 alkyl.  2. The method according to claim 1 for the protection of non-living materials other than wood and objects made from it or coated with said non-living material from bacteria and polluting organisms, which consists in applying an effective antibacterial or anti-polluting amount to the surface or including in said materials or objects compounds of formula I.  3. The method according to claim 2, where the compound of formula I is 5,6-dihydro-3- (2-thienyl) -1,4,2-oxathiazine, 4-oxide, or 3- (4-chlorophenyl) -5, 6-dihydro-1,4,2-oxathiazine, 4,4-dioxide.  4. The method according to claim 2, in which the non-living material is an adhesive material for coatings, such as paint, anti-pollution paint, drying oil, varnish, finish or whitewash.  5. The method according to claim 4, in which the sticky coating material is preserved in storage containers or where the coating material is applied in the form of a film to a substance.  6. The method according to claim 2 for the protection of underwater objects, such as hulls of ships, devices in the port, drainage docks, lock gates, dams, mooring masts, buoys, drilling platforms, bridges, pipelines, fishnets, cables and any other objects in constant or frequent contact with water, which consists in applying to these objects an anti-contaminant composition, for example, a coloring composition containing an effective anti-contaminant amount of a compound of formula I as defined in claim 1.  7. The method according to claim 2, in which the amount of the compound of formula I ranges from 0.001 to 95 wt.% Of the total weight of the composition.  8. A coating composition comprising (a) as an active ingredient a compound of formula I as defined in claim 1, and (b) polymers or copolymers derived from monomers such as dialkylsiloxanes, (meth) acrylic acid, (meth) acrylic esters acids, vinyl or allyl alcohols and derivative esters, maleic acid, styrene, vinyl chloride, butadiene, acrylamide, acrylonitrile or resins such as alkyd resins, polyurethanes, epoxies, phenol resins and urea-formaldehyde resins.  9. The coating composition of claim 8, further comprising one or more additives selected from the group consisting of water-repellent agents, surface-friction agents, organically binding agents, insecticides, fungicides, bactericides, auxiliary solvents, processing aids, primers paint, plasticizers, UV stabilizers or stability modifiers, paints, colored pigments, desiccants, corrosion inhibitors, anti-deposition agents, anti-seize agents and anti-foaming agents.  10. The anti-contaminant coloring composition of claim 8, containing from 10 to 75 wt.% The active ingredient relative to the total dry weight of the specified anti-contaminating coloring composition.
