Abstract
Official abstract text for this publication.
Provided is a polymerizable composition hardly having oxygen inhibition layer by polymerization under an oxygen environment, including a first paste including (a) a (meth)acrylate compound, (b) at least one of an aromatic sulfinic acid and a salt thereof, and (c) an acidic compound; and a second paste including (a) a (meth)acrylate compound, (d) an organic metal compound, and (e) an organic halogen compound, wherein at least either one of the first paste and the second paste includes (f) a filler.
First claim
Opening claim text (preview).
The invention claimed is: 1. A two-paste polymerizable composition comprising: a first paste including (a) a (meth)acrylate compound, (b) at least one of an aromatic sulfinic acid and a salt thereof, and (c) an acidic compound; and a second paste including (a) a (meth)acrylate compound, (d) an organic metal compound, and (e) an organic halogen compound, wherein at least either one of the first paste and the second paste includes (f) a filler. 2. The two-paste polymerizable composition according to claim 1 , comprising: the first paste including (a) a (meth)acrylate compound: in the range of from 15 mass % to 95 mass %, (b) at least one of an aromatic sulfinic acid and a salt thereof: in the range of from 0.01 mass % to 5 mass %, (c) an acidic compound: in the range of from 0.01 mass % to 20 mass %, and (f) a filler: in the range of from 5 mass % to 80 mass %; and the second paste including (a) a (meth)acrylate compound: in the range of from 15 mass % to 95 mass %, (d) an organic metal compound: in the range of from 0.001 mass % to 1 mass %, (e) an organic halogen compound: in the range of from 0.001 mass % to 10 mass %, and (f) a filler: in the range of from 5 mass % to 80 mass %. 3. A two-paste polymerizable composition comprising: a first paste including (a′) a (meth)acrylate compound not having acid groups, (a″) a (meth)acrylate compound having an acid group(s), and (b) at least one of an aromatic sulfinic acid and a salt thereof; and a second paste including (a) a (meth)acrylate compound, (d) an organic metal compound, and (e) an organic halogen compound, wherein at least either one of the first paste and the second paste includes (f) a filler. 4. The two-paste polymerizable composition according to claim 3 , comprising: the first paste including (a′) a (meth)acrylate compound not having acid groups and (a″) a (meth)acrylate compound having an acid group(s), whose total amount is: in the range of from 15 mass % to 95 mass %, (b) at least one of an aromatic sulfinic acid and a salt thereof: in the range of from 0.01 mass % to 5 mass %, and (f) a filler: in the range of from 5 mass % to 80 mass %; and the second paste including (a) a (meth)acrylate compound: in the range of from 15 mass % to 95 mass %, (d) an organic metal compound: in the range of from 0.001 mass % to 1 mass %, (e) an organic halogen compound: in the range of from 0.001 mass % to 10 mass %, and (f) a filler: in the range of from 5 mass % to 80 mass %. 5. A two-paste polymerizable composition comprising: a first paste including (a) a (meth)acrylate compound, (b) at least one of an aromatic sulfinic acid and a salt thereof, and (c) an acidic compound; and a second paste including (a) a (meth)acrylate compound, (d) an organic metal compound, and (e) an organic halogen compound, wherein neither the first paste nor the second paste includes (f) a filler.
