Title: TEMPORARY ADHESIVE COMPOSITION AND LAMINATE
Abstract:
Provided are: a temporary adhesive composition which temporarily fixes substrates that can subsequently be appropriately peeled off, and which is capable of providing a laminate in which the surface condition of a substrate following processing is satisfactory; and a laminate. The temporary adhesive composition contains a resin and polyether-modified silicone A in which the ratio represented by equation (A) below is at least 80%, wherein the content of the polyether-modified silicone A is 0.001-1.0 mass% of the solid content of the temporary adhesive composition (Equation (A): {(MO+EO)/AO}×100). In the above equation (A), MO represents the mole% of methylene oxide contained in a polyether structure in the polyether-modified silicone, EO represents the mole% of ethylene oxide contained in the polyether structure in the polyether-modified silicone, and AO represents the mole% of alkylene oxide contained in the polyether structure in the polyether-modified silicone.
