-30 parts by weight is more preferred. If the amount added is less than 0.01 parts by weight, the crosslinking effect will be low, and if it exceeds 50 parts by weight, the adhesion of the heat-resistant coating layer will decrease, and furthermore, the coating properties will deteriorate, making it difficult to form a uniform layer. Further, as the crosslinking accelerator, known ones such as salts, inorganic substances, organic substances, acid substances, and alkaline substances can be used. The amount of the crosslinking promoter to be added is 0.00 parts by weight based on 100 parts by weight of the solid content of the poly(meth)acrylate copolymer containing the reactive monomer.
