POLYMERIZABLE COMPOSITION, PHOTOPOLYMERIZABLE COMPOSITION AND PIPE-LINING MATERIAL AND PIPE-LINING METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a pipe-lining material excellent in curing properties. SOLUTION: The pipe-lining material is obtained by impregnating a fiber- reinforcing material with a photopolymerizable resin composition that comprises as essential components (a) a photopolymerization initiator having a photosensitivity in a visible region, (b) a curing agent having a ten-hour half-life temperature of not higher than 80 deg.C, (c) a resin bearing a vinyl group and (d) a polymerizable monomer.
