Claim Text:
1. A curable composition, comprising: an organic polymer (A), having a number-average molecular weight of 800 to 15,000, and comprising 0.5 or more but less than 1.2 reactive silicon groups in each molecule of the polymer on average, the silicon group being represented by the following general formula (1): wherein R 1 represents a bivalent organic group having 1 to 20 carbon atoms and containing, as one or more constituent atoms, one or more selected from the group consisting of hydrogen, carbon and nitrogen atoms; R 2 represents an alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, an aralkyl group having 7 to 20 carbon atoms, or a triorganosiloxy group represented by —OSi(R′) 3 wherein the three R's, which may be the same or different, are each a monovalent hydrocarbon group having 1 to 20 carbon atoms; X represents a hydroxyl group or a hydrolysable group provided that when Xs, the number of which is two or more, are present, Xs may be the same or different; Y is a heteroatom, and is selected from an oxygen atom or a nitrogen atom; and a is an integer of 1 to 3; and an organic polymer (B) having a number-average molecular weight of 5,000 to 50,000 and having 1.2 to 5 reactive silicon groups in each molecule of the organic polymer (B) on average.
