摘要： Provided is a dental plate liner which has a paste-like form free of the complexity of the measuring and mixing of a powder material and a liquid material, which can provide a viscosity increase comparable to that of a related-art dental plate liner formed of a powder material and a liquid material, which is excellent in workability, and which is free of a problem of stain because of, for example, its coloring resistance. The dental plate liner includes: a paste (i) containing (A) a (meth)acrylic acid-based polymer, and a fluorine-containing (meth)acrylic acid-based polymerizable monomer in which (A) the (meth)acrylic acid-based polymer has a solubility of less than 20 mass%; and a paste (ii) containing a (meth)acrylic acid-based polymerizable monomer in which (A) the (meth)acrylic acid-based polymer has a solubility of 20 mass% or more, and a filler, in which at least one paste selected from the group consisting of the paste (i) and the paste (ii) contains a polymerization initiator, and in which the dental plate liner is used through mixing of the paste (i) and the paste (ii) immediately before use.
