13 Claims

1. An adhesive composition for use in debonding with light irradiation, which composition can achieve debonding through irradiation with light, wherein:

the adhesive composition comprises:

an adhesive component (S) that is curable through hydrosilyation, and

a light-absorbing organic compound (X); and

the light-absorbing organic compound (X) contains, in the molecule thereof, one or more aromatic rings, one or more rings each containing a heteroatom forming the ring, and one or more groups selected from among a carbonyl group and a thiocarbonyl group,

wherein the carbon atoms of the carbonyl or thiocarbonyl group constitute the ring that contains the hetereatom in the ring.
