Abstract:
1. A temporary adhesive composition comprising: (A) non-aromatic saturated hydrocarbon group-containing organopolysiloxane; (B) an antioxidant; and (C) an organic solvent, wherein the component (A) corresponds to 100 parts by mass, the component (B) corresponds to 0.5 to 5 parts by mass, and the component (C) corresponds to 10 to 1000 parts by mass, and wherein the non-aromatic saturated hydrocarbon group-containing organopolysiloxane of the component (A) is organopolysiloxane (A-1) that has a weight average molecular weight of 2,000 to 60,000, is insoluble in a polar solvent having an SP value higher than 9, and contains units represented by the following (I) to (III) or organopolysiloxane (A-2) obtained by increasing a molecular weight using the organopolysiloxane (A-1) as a starting material: (I) a siloxane unit represented by R (II) a siloxane unit represented by R (III) a siloxane unit represented by R wherein each of R
