A metal primer comprising an organic solution containing A) a (meth) acrylate monomer having a sulfur atom in the molecule and B) an acidic group-containing radical polymerizable monomer, C) an organic solvent comprising: Although it is an alcohol-based alcohol having little biological harm and moderate volatility, the amount of the A) (meth) acrylate monomer having a sulfur atom in the molecule is small, and after long-term storage Develop a material that can maintain sufficient adhesiveness in In a metal primer comprising an organic solution having the above composition, the content of (meth) acrylate monomer having at least one sulfur atom in the molecule is 0.01 based on the mass of the whole primer. As a further 3% by mass, C) a secondary alcohol or tertiary alcohol is used as the organic solvent. [Selection figure] None |
