Beschreibung
Zusammenfassung:	A photocurable silicone composition, a method of forming a coating from such compositions, and an article comprising a coating formed from such compositions and/or methods are shown and described herein. The photocurable silicone composition comprises (i) a vinyl functional polysiloxane; (ii) a hydride functional polysiloxane; (iii) a photoactive catalyst; and (iv) an acid-anhydride functional polysiloxane. The composition and method can be employed to process thin coatings onto paper and film substrates followed by exposure to actinic radiation at ambient conditions of temperature and atmosphere for manufacture of release liners.
