[Problems] A primer used for pre-treating the surfaces of a prosthetic, which exhibits a large adhering force at the time of adhering a prosthetic of metal oxide ceramics to an object to be joined by using an adhesive such as a dental cement, the large adhering force being maintained for extended periods of time even in a severe environment such as in an oral cavity.
[Means for Solution] A primer composition for metal oxide ceramics, comprising (A) a polymerizable monomer component containing 5% by mass or more, preferably, 5% by mass to 80% by mass of an acidic group-containing polymerizable monomer as represented by a 11-methacryloyloxy-1,1-undecanedicarboxylic acid and a rest of a polymerizable monomer without acidic group, such as triethylene glycol dimethacrylate; (B) polyvalent metal ions resulting from a titanium tetrabutoxide or the like; and (C) an organic solvent such as acetone or ethyl alcohol, wherein water is not substantially contained.
[问题]一种用于预处理修复体表面的处理剂,在使用牙科粘合剂等粘合剂将金属氧化物陶瓷修复体粘合到待粘合物体上时,该处理剂显示出较大的粘合力,即使在口腔等恶劣环境中,也能长时间保持较大的粘合力。
[解决方法]一种用于金属氧化物陶瓷的底层涂料组合物,包括 (A) 可聚合单体组分,其中含有 5%(按质量)或更多,优选 5%(按质量)至 80%(按质量)的含酸性基团的可聚合单体,以 11-甲基丙烯酰氧基-1,1-十一烷二羧酸为代表,其余为不含酸性基团的可聚合单体,如三甘醇二甲基丙烯酸酯;(C) 有机溶剂,如丙酮或乙醇,其中基本上不含水。
