Abstract: A curable organopolysiloxane composition comprising: (A) at least one type of gum-like or liquid organopolysiloxane having a viscosity of not less than 20 mPa·s, a content of the vinyl(CH2?CH—) part of higher alkenyl groups being in a range of 2.0 to 5.0% by mass; (B) an organopolysiloxane resin formed essentially from R13SiO1/2 units and SiO4/2 units, a molar ratio of the R13SiO1/2 units to the SiO4/2 units being from 0.5 to 2.0 and a content of the vinyl(CH2?CH—) part of alkenyl groups being less than 1.0% by mass; (C) an organohydrogenpolysiloxane; (D) a hydrosilylation reaction catalyst; and, optionally, (E) an organic solvent. In such a composition, a mass ratio of the component (A) to the component (B) is in a range of 2/8 to 8/2.

Abstract: To provide a laminate comprising a substrate and a cured silicone product, wherein the substrate and the cured silicone product are integrated well and the cured silicone product provides superior electrification preventing or reducing properties to the laminate. A laminate comprising: a substrate (L1), a primer layer (L2) formed on the substrate (L1), and a cured silicone layer (L3) including a lithium salt (a) and a polyether modified polysiloxane (b), which is formed on the primer layer (L2). The laminate can be used for a releasable or adhesive film.

Abstract: Imparting superior electrification preventing or reducing properties to a cured silicone product without inhibiting adhesion between a substrate and the cured silicone product when integrating the substrate and the cured silicone product via a primer layer. A condensation reaction curable primer composition comprising a lithium salt (a) and a polyether modified polysiloxane (b); and a laminate obtained by integrating a substrate and a cured silicone product using an electrification preventing or reducing primer layer (cured product of the composition).
