Abstract
Official abstract text for this publication.
To provides a polymerizable composition having high storage stability and high color stability. To provide a two-paste type dental polymerizable composition of the present invention is a two-paste type dental polymerizable composition comprising a first paste containing (A) at least one kind of polemerizable monomer, an (B) organic peroxide as a chemical polymerization initiator, and a (C) basic filler, and a second paste containing (A) at least one kind of polemerizable monomer, a (C) basic filler and an (D) aromatic amine compound as a chemical polymerization accelerator, wherein the second paste contains 30 to 80 parts by weight of the (C) basic filler based on 100 parts by weight of the total amount of the second paste.
First claim
Opening claim text (preview).
What is claimed is: 1. A two-paste type dental polymerizable composition comprising: a first paste containing (A) at least one polymerizable monomer, an (B) organic peroxide as a chemical polymerization initiator, and a (C) basic filler, and a second paste containing (A) at least one polymerizable monomer, a (C) basic filler and an (D) aromatic amine compound as a chemical polymerization accelerator, wherein the second paste contains 30 to 80 parts by weight of the (C) basic filler based on 100 parts by weight of the total amount of the second paste, a dispersion of 1.0 g of the (C) basic filler in a mixed solution of 40 g of distilled water and 10 g of ethanol has a pH-value in the range from 7.5 to 9.0 after stirring for 1 hour, and the first paste and the second paste contain no acidic group-containing compound. 2. The two-paste type dental polymerizable composition according to claim 1 , wherein: the total compounding amount of the (C) basic filler contained in the first paste and the second paste is in the range from 40 to 80 parts by weight based on 100 parts by weight of the total composition of the first paste and the second paste. 3. The two-paste type dental polymerizable composition according to claim 1 , wherein: the first paste and the second paste contain substantially no water. 4. The two-paste type dental polymerizable composition according to claim 1 , wherein: a volume mixing ratio of the first paste to the second paste is in the range from 1:0.9 to 0.9:1. 5. The two-paste type dental polymerizable composition according to claim 2 , wherein: the first paste and the second paste contain substantially no water. 6. The two-paste type dental polymerizable composition according to claim 2 , wherein: a volume mixing ratio of the first paste to the second paste is in the range from 1:0.9 to 0.9:1. 7. The two-paste type dental polymerizable composition according to claim 3 , wherein: a volume mixing ratio of the first paste to the second paste is in the range from 1:0.9 to 0.9:1.
