An oil repellent agent including a modified natural product having at least one hydroxyl group, wherein a hydrogen atom of the hydroxyl group is replaced with an R group represented by —Y—Z, wherein Y represents a direct bond, —C(═O)—, —C(═O)—NR′— or —C(═S)—NR′—, where R′ represents a hydrogen atom or a C.sub.1 to C.sub.4 alkyl group); and Z represents a hydrocarbon group having 1 to 40 carbon atoms and optionally having a substituent or a polysiloxane. The natural material is a natural product other than starch and preferably is a monosaccharide, a polysaccharide, glycerin or polyglycerin. Also disclosed is a textile product to which the oil-resistant agent is attached, an oil-resistant paper and a method of treating paper with the oil-resistant agent.

The present invention provides a biodegradable formulation and its use as a surfaces restoring agent, said formulation allows a substantial savings when restoring the existing paint on different surfaces, since it mainly cleans and restores the surface or paint contaminated by the environment, damaged due to the sun and the processes of the different industries, in addition to being friendly to the environment, making it a useful technology in any industrial branch that involves cleaning and restoring large areas. It is worth noting that the modifications to the original formula were made to optimize the results in the different applications and improve its biodegradability.

A preparation method for an ultraviolet-responsive coumarin controlled-release and self-repairing anti-fouling paint includes: reacting double-end-group reactive polydimethylsiloxane, polyisocyanate, and an organic diluting solvent; adding a dihydroxycoumarin compound, a cross-linking agent and an organotin catalyst; adding a simple coumarin compound, and irradiating the mixture with 365 nm ultraviolet light to obtain the anti-fouling paint. An anti-fouling coat formed by the paint of the present invention has the advantages of controllable release of a coumarin green anti-fouling agent in response to external ultraviolet stimulation and self-repairing, and the problems that the release of the conventional anti-fouling agents in the anti-fouling coat is difficult to control, and that the low-surface-energy anti-fouling coat is difficult to repair after being damaged are solved. The anti-fouling application requirements of various shallow sea light-transmitting constructions can be met, the service life is prolonged, and the application performance in a complex real sea environment is enhanced.

The present invention relates to an antireflection film. The antireflection film includes a low refractive index layer having excellent alkali resistance and exhibiting remarkably improved mechanical properties such as scratch resistance and impact resistance as well as reduction of a glare phenomenon, and a base film exhibiting excellent mechanical strength and water resistance in spite of a thin thickness and having no fear of interference fringes occurring. Therefore, such antireflection film can be used as a protective film of a polarizing plate or used as any other component so as to provide a thin display device, and furthermore, can effectively prevent the glare phenomenon of the display device, and can more improve the durability and lifespan thereof.
