< Topic >Revision and supplementation ones which consist of the metallic oxide ceramics at the time of, it reveals the high adhesive strength adhesion to the connected object making use of adhesive such as dental cement furthermore this high adhesive strength is long term continuance possible even under severe environment of environment and the like inside the buccal cavity, it designates that the primer which is used for the preprocessing of the revision and supplementation thing surface is developed as purpose.SolutionsThe acidic basic content polymerizability monomer which is represented in (A)11 methacryloyloxy 1,1 undecane di-carboxylic acid is included 5 mass % above, 5 mass % - 80 mass % desirably, the primer constituent for the metallic oxide ceramics which features that, the remainder becomes, is not included containing (B) (C) organicity solvent such as polyvalent metal ion, and acetone and ethyl alcohol of origin such as polymerizability monomer component, and chitaniumutetorabutokishido which consist of the polymerizability monomer which the acidic basis of toriechirengurikorujimetakurireto and the like the possession is not done the water substantially.< Choice figure >It is not【課題】金属酸化物セラミックスからなる補綴物を歯科用セメントなどの接着材を用いて被接合物に接着させるに際して、高い接着力を発現し、しかもこの高い接着力が口腔内環境等の苛酷な環境下でも長期間持続可能である、補綴物表面の前処理に使用されるプライマーを開発することを目的とする。【解決手段】(A)11-メタクリロイルオキシ-1,1-ウンデカンジカルボン酸に代表される酸性基含有重合性単量体を5質量%以上、好ましくは5質量%~80質量%含み、残部はトリエチレングリコールジメタクリレート等の酸性基を有しない重合性単量体からなる重合性単量体成分、チタニウムテトラブトキシドなど由来の(B)多価金属イオン、およびアセトンやエチルアルコールなどの(C)有機溶媒を含有してなり、実質的に水を含まないことを特徴とする金属酸化物セラミックス用のプライマー組成物。【選択図】なし
