Abstract: A method of coating an article includes applying a polymerizable composition onto an article, and polymerizing the polymerizable composition applied onto the article. The polymerizable composition includes a first polymerizable monomer and a solution dispersed in the first polymerizable monomer. The solution includes a first solvent and a second polymerizable monomer dissolved in the first solvent. The first polymerizable monomer is a liquid, and the second polymerizable monomer is a solid.
