Abstract
Abstract An ultraviolet-curing composition comprising an ultraviolet-curing resin having active OH group or COOH group, a vinyl monomer, a thickening agent and a photo-sensitizer. A prepreg sheet containing the composition. A metallic material having anticorrosive coating which comprises a metallic material coated with a coating material mainly comprising petrolatum and further with another coating material mainly comprising the above composition. A metallic material having an anticorrosive coating which comprises a metallic material on the surface of which a rust-proof paint layer is provided and the surface of which layer is further coated with a coating material mainly comprising the above composition. The above composition and prepreg sheet are useful for the lining of metallic members of frame-work and structures.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
38 words
An ultraviolet-curing composition comprising an ultraviolet-curing resin having active OH group or COOH group, a vinyl monomer, a thickening agent which is reactive with the active OH group or COOH group of the ultraviolet-curing resin, and a photosensitizer.
Claim 2
Dependent Claim
38 words
An ultraviolet-curing composition comprising an ultraviolet-curing resin having active OH group or COOH group, a vinyl monomer, a thickening agent which is reactive with the active OH group or COOH group of the ultraviolet-curing resin, and a photosensitizer.
Claim 3
Dependent Claim
