To provide a photocurable one-pack type putty for repairing sheet metal, which cures rapidly by harmless visible light. A photocurable putty for repairing sheet metal comprising: (a) 100 parts by weight (33.3 % to 73.5 % by weight based on the total amount of the components (a) to (c)) of a bisphenol A type epoxy di(meth)acrylate; (b) 1 to 100 parts by weight (0.7 % to 33.3 % by weight based on the total amount of the components (a) to (c)) of a photopolymerizable (meth)acrylate; (c) 35 to 100 parts (25.7 % to 33.3 % by weight based on the total amount of the components (a) to (c)) by weight of a photopolymerizable urethane oligomer having two or more (meth)acryloyloxy groups per molecule; and (d) 0.01 to 10 parts by weight of .alpha.-diketone as a photoinitiator, 0.01 to 10 parts by weight of tertiary amine as a photosensitizer and 0.01 to 5 parts by weight of an onium salt as a photoreaction accelerator, each amount being based on 100 parts by weight of the total amount of the components (a) to (c).

L'invention concerne un mastique photodurcissable du type à un composant pour la réparation de tôle métallique, durcissant rapidement sous l'effet de lumière visible inoffensive. Un mastique photodurcissable de réparation de tôle de l'invention comprend: (a) 100 parties en poids (33,3 % à 73,5 % en poids calculé d'après la quantité totale des composants (a à c)) d'un di(méth)acrylate époxy de type bisphénol A; (b) 1 à 100 parties en poids (0,7 % à 33,3 % en poids calculé d'après la quantité totale des composants (a à c)) d'un (méth)acrylate photopolymérisable; (c) 35 à 100 parties (25,7 % à 33,3 % en poids calculé d'après la quantité totale des composants (a à c)) en poids d'un oligomère uréthane photopolymérisable ayant deux ou plusieurs groupes (méth)acryloyloxy par molécule; et (d) 0,01 à 10 parties en poids d'une .alpha.-dicétone comme photoinitiateur, 0,01 à 10 parties en poids d'une amine tertiaire comme photosensibilisateur et 0,01 à 5 parties en poids d'un sel d'onium comme accélérateur de photoréaction, chaque quantité étant calculée sur 100 parties en poids de la quantité totale des composants (a à c).
