PURPOSE:To obtain a thermosetting covering sheet having good malleability, ductility and flexibility before being cured and capable of forming a film of a high hardness after being cured, which is an uncured sheet based on a composition comprising a specified reactive acrylic resin, a blocked isocyanate, a thermoplastic resin and/or a specified reactive acrylic oligomer. CONSTITUTION:An uncured thermosetting covering sheet formed from a thermosetting resin composition mainly comprising a normally solid reactive acrylic resin having a weight-average MW of 100000-1000000, a blocked isocyanate and a normally solid thermoplastic resin and/or a reactive acrylic oligomer of a weight-average MW of 1000-10000. The above composition may further contain at least one crosslinking agent selected from among a nonblocked isocyanate, a melamine compound and an epoxy compound. |
