ABSTRACT:
A photocurable bandage or splint consisting of a flexible fabric, a photosensitizer and a reaction product of a hydroxyalkyl acrylate or methacrylate, a diisocyanate and a polyhydric alcohol. The photocurable bandage or splint can be produced without using a solvent and a volatile monomer by using a process which comprises impregnating the flexible fabric with a reaction mixture obtained by adding the polyhydric alcohol to a reaction product of the hydroxyalkyl acrylate or methacrylate and the diisocyanate which contains free isocyanate groups, and reacting the polyhydric alcohol with the isocyanate groups on the fabric to form a photocurable composition.
