Claims
- 1. A polymerizable material consisting essentially of a mixture of (a) 50 to 90% by weight of one or more cationically polymerizable compounds and an onium compound as a cationic polymerization initiator therefor, and (b) 10 to 50% by weight of one or more free-radically polymerizable methacrylates and a camphorquinone-amine system as a free-radical polymerization initiator therefor, and wherein the content of the cationic polymerization initiator is 0.3 to 4% by weight and that of the free-radical polymerization initiator is 0.1 to 5% by weight; and, optionally, (c) a fine-particle organic filler, a fine-particle inorganic filler, or a combination thereof
- wherein the cationically polymerizable compounds are one or more of the compounds ##STR7##
- 2. Polymerizable material as claimed in claim 1, wherein the content of cationic-polymerization initiator is 0.5 to 1.5% by weight and the content of the radical-polymerization initiator is 0.3 to 1% by weight.
- 3. Polymerizable material as claimed in claim 1, wherein the cationic photopolymerization initiator is in the form of a sulfonium salt.
- 4. Polymerizable material as claimed in claim 1, wherein the cationic photopolymerization initiator is in the form of an iodonium salt.
- 5. Polymerizable material as claimed in claim 1, wherein (a) the content of cationic-polymerization initiator is 0.5 to 1.5% by weight and the content of the radical-polymerization initiator is 0.3 to 1% by weight; (b) the cationic photopolymerization initiator is in the form of a sulfonium salt or an iodonium salt and (c) the radical-photopolymerization initiator is a camphorquinone-amine system.
- 6. Polymerizable material as claimed in claim 1, further containing 20 to 95% by weight of the polymerizable mixture and 5 to 80% by weight of fine-particle organic filler, fine-particle inorganic filler, or a combination thereof.
- 7. Polymerizable material as in claim 6, wherein the fine-particle organic filler is an alkyl-methacrylate homopolymer or copolymer.
- 8. Polymerizable material as claimed in claim 6, wherein the fine-particle inorganic filler is a lithium-aluminum, barium-aluminum, or strontium-aluminum silicate glass, a barium-aluminum borosilicate glass, silicon dioxide, or a mixture thereof.
- 9. Dental material essentially consisting of a polymerizable material as claimed in claim 1.
- 10. Bone cement essentially consisting of a polymerizable material as claimed in claim 1.
- 11. Coating materials essentially consisting of a polymerizable material as claimed in claim 1, for the manufacture of coatings for ceramic, glass, metal, wood, paper or plastic.
