  • Method for manufacturing laminated steel sheet, apparatus for manufacturing laminated steel sheet, and curable composition used for the same
    Patent number: 11872619
    Abstract: A method is for manufacturing a laminated steel sheet comprising laminated a predetermined number of thin steel sheets formed by punching a belt-shaped thin steel sheet into a predetermined shape. This method includes the following steps 1 to 3: step 1: a step of sequentially punching the thin steel sheet into a predetermined shape with a metallic die; step 2: a step of applying a curable composition to a predetermined portion of the thin steel sheet; and step 3: a step of irradiating the curable composition with energy rays. The curable composition is a delayed curable composition which is cured after a lapse of a predetermined time after being irradiated with energy rays.

  • CURABLE COMPOSITION
    Publication number: 20220389129
    Abstract: The present invention provides a curable composition capable of securing delayed curing time for carrying out a work such as laminating or tightening after carrying out irradiation with an energy ray or heating and capable of exhibiting delayed curing property after that, regardless of whether an adherend is transparent or not. The present invention is a curable composition comprising components (A) to (C): a component (A): a compound having a (meth)acryloyl group in a molecule; a component (B): saccharin; and a component (C): at least one of a photocationic catalyst as a component (C-1) and a thermal cationic catalyst as a component (C-2).
