WIPO Patent Application WO/2018/212257

Kind Code:

A1

Abstract:

Provided is an adhesive composition which is cured at low temperatures and is capable of forming a cured product that has excellent insulating properties, heat resistance and adhesiveness. An adhesive composition according to the present invention contains a polyorganosilsesquioxane (A) which has a constituent unit represented by formula (1), and wherein: the proportion of the constituent unit represented by formula (1) and the constituent unit represented by formula (2) relative to the total amount of siloxane constituent units (100 mol%) is 55-100 mol%; the number average molecular weight is from 1,500 to 50,000; and the degree of molecular weight dispersity ((weight average molecular weight)/(number average molecular weight)) is from 1.0 to 4.0. R1SiO3/2 (1) (In formula (1), R1 represents a group containing a radically polymerizable group.) R1SiO2 /2(OR2) (2) (In formula (2), R1 is as defined above, and R2 represents a hydrogen atom or an alkyl group having 1-4 carbon atoms.)
