Abstract: 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.

Abstract: The present invention relates to a crosslinked polyacrylate salt, which has been neutralized by two types of amines: (1) amine groups attached to the polymer backbone of an aminosilicone and (2) water soluble organic amines. The compositions of the present invention can readily swell in water, displaying enhanced thickening, emulsifying, dispersing and producing film with water resistance compared to acrylate based thickener alone. The compositions can be used to formulate a wide variety of ingredients, such as, for example, fatty substances, humectants, solid particles, silicones, organic or inorganic sunscreens, without the need of further neutralizing agents, dispersants or emulsifiers.
