  An object of the invention is to yield a highly transparent cured article wherein bubbles are less generated when a catalyst and others are added to a curable composition that contains an organic polymer having a silicon-containing group which can be crosslinked by the formation of a siloxane bond and then the resultant mixture is stirred. Another object thereof is to provide a cured article which is small in surface stickiness, slightly gets dirty over a long term, and has a practical adhesiveness. These objects are attained by a curable composition which comprises (A) an organic polymer having a silicon-containing group that can be crosslinked by the formation of a siloxane bond, (B) a bivalent tin carboxylate and (C) an amine compound having no reactive silicon group, and which turns transparent when cured; or a transparent cured article obtained by curing the composition.

  本发明的一个目的是产生一种高透明度的固化物，当催化剂和其他物质加入到含有有机聚合物的可固化组合物中时，气泡产生较少，该有机聚合物具有含硅基团，可通过形成硅氧烷键而交联，然后搅拌所得混合物。其另一个目的是提供一种固化物，这种固化物表面粘性小，长期使用不会变脏，并且具有实用的粘合性。这些目标可以通过一种固化组合物来实现，该组合物包括：(A) 具有可通过形成硅氧烷键而交联的含硅基团的有机聚合物；(B) 二价羧酸锡；(C) 不含活性硅基团的胺化合物，固化后变成透明；或通过固化该组合物得到的透明固化物。
