Claims
- 1. A process for bonding ceramics to an adherend using a liquid containing (a) a silane coupling agent and (b-1) at least one first acidic compound selected from the group consisting of organic carboxylic acids, organic carboxylic acid anhydrides, inorganic acids, organic sulfonic acids and organic phosphoric acids, and a mixture containing (c) a polymerizable monomer and (d) a polymerization catalyst, the amount of said silane coupling agent being at least 5% by weight based on the sum total weight of said components (a), (b-1), (c) and (d), which process involves the following steps of
- (1) applying said liquid containing said components (a) and (b-1) to the surface of the ceramics,
- (2) drying the liquid thus applied to the surface of the ceramics to form a coat layer,

- 7. The process as claimed in claim 1 wherein the polymerizable monomer consists of methyl methacrylate and 4-methacryloxyethyltrimellitic acid anhydride.
- 8. The process as claimed in claim 1 wherein the polymerization catalyst is trialkylboron or its oxide, or a mixture system of organic peroxides and amines.
- 9. A process for bonding ceramics to an adherend using a liquid containing (a) a silane coupling agent and (b-2) a metal salt, and a mixture containing a polymerizable monomer and a polymerization catalyst, which process involves the following steps of
- (1) applying said liquid containing said components (a) and (b-2) to the surface of the ceramics,
- (2) drying the liquid thus applied on the surface of the ceramics to form a coat layer,
- (3) applying said mixture containing said polymerizable monomer and said polymerization catalyst to said coat layer, and
- (4) bonding said adherend to the surface of the thus treated ceramics.
- 10. The process as claimed in claim 9 wherein the adherend is metal or ceramics.
- 11. The process as claimed in claim 9 wherein the silane coupling agent is .gamma.-methacryloxypropyl trimethoxysilane, .gamma.-methacryloxypropyl tri(trimethylsiloxy)silane or .gamma.-methacryloxypropyl pentamethyldisiloxane.
- 12. The process as claimed in claim 9 wherein the metal salt is ferric chloride, magnesium chloride, zinc chloride, aluminum chloride, stannous chloride, stannic chloride, molybdenum chloride, nickel chloride, cupric chloride or cobalt chloride.
- 13. The process as claimed in claim 9 wherein the polymerizable monomer is methyl methacrylate.
- 14. The process as claimed in claim 9 wherein the polymerizable monomer consists of methyl methacrylate and 4-methacryloxyethyltrimellitic acid anhydride.
- 15. The process as claimed in claim 9 wherein the polymerization catalyst is trialkylboron or its oxide, or a mixture system of organic peroxides and amines.
- 16. A process for bonding ceramics to an adherend using a liquid containing (a) a silane coupling agent and (b-2) a metal salt, and a mixture containing (c) a polymerizable monomer, (d) a polymerization catalyst and (b-3) at least one second acidic compound selected from the group consisting of organic carboxylic acids and organic carboxylic acid anhydrides, which process involves the following steps of
- (1) applying said liquid containing said components (a) and (b-2) to the surface of the ceramics,
- (2) drying the liquid thus applied to the surface of the ceramics to form a coat layer,
- (3) applying said mixture containing said components (c), (d) and (b-3) to said coat layer, and
- (4) bonding said adherend to the surface of the thus treated ceramics.
- 17. The process as claimed in claim 16 wherein the adherend is metal or ceramics.
- 18. The process as claimed in claim 16 wherein the silane coupling agent is .gamma.-methacryloxypropyl trimethoxysilane, .gamma.-methacryloxypropyl tri(trimethylsiloxy)silane or .gamma.-methacryloxypropyl pentamethyldisiloxane.
- 19. The process as claimed in claim 16 wherein the metal salt is ferric chloride, magnesium chloride, zinc chloride, aluminum chloride, stannous chloride, stannic chloride, zirconium chloride, molybdenum chloride, nickel chloride, cupric chloride or cobalt chloride.
- 20. The process as claimed in claim 16 wherein the polymerizable monomer is methyl methacrylate.
- 21. The process as claimed in claim 16 wherein the polymerizable monomer consists of methyl methacrylate and 4-methacryloxyethyltrimellitic acid anhydride.
- 22. The process as claimed in claim 16 wherein the polymerization catalyst is trialkylboron or its oxide, or a mixture system of organic peroxides and amines.
