Disclosed is a thermosetting protective solution for a glass mask, which exhibits good adhesion to a glass mask. When the thermosetting protective solution for a glass mask is formed into a protective film, the protective film has excellent hardcoat properties, while being free from cracks and capable of preventing the whitening of the coating film due to the incompatibility between an epoxy resin and a silicone resin. In addition, the thermosetting protective solution for a glass mask has improved storage stability since the protective solution only contains an amine compound as a curing agent. Specifically disclosed is a thermosetting protective solution for a glass mask, which contains a silicone resin, an epoxy resin and a silicone oil. A phenolic novolac epoxy resin is contained as the epoxy resin. The thermosetting protective solution for a glass mask additionally contains an amine compound but does not contain any metal alkoxide catalyst, as a curing agent. |
