摘要： An ultraviolet-curable silicone composition for a release paper including (A) 100 parts by mass of a specific organopolysiloxane having a polymerization degree of 8 to 20 and containing one epoxy group, and (C) an effective quantity of an onium salt photoinitiator. In a preferred embodiment, the composition further includes (B) 10 to 1,000 parts by mass of at least one specific organopolysiloxane containing a plurality of epoxy groups. In another preferred embodiment, the composition has a viscosity of not more than 100 mPa·s. The composition has a peel strength that exhibits a positive dependency on the peel speed when peeled from a hot-melt pressure-sensitive adhesive, and can therefore be used to produce a release paper capable of reducing peeling noise. Further, because the composition has a low viscosity, it exhibits excellent wetting of substrates having significant unevenness, even in a solventless form.
