摘要： The present invention is an addition reaction-curable silicone emulsion composition containing a water-soluble silane coupling agent (I) and an organopolysiloxane (II) having at least two alkenyl groups in one molecule thereof, where the water-soluble silane coupling agent (I) has at least one group selected from among a succinic anhydride group, a quaternary ammonium group, and a ureido group, and 1 part by mass or more of the water-soluble silane coupling agent (I) is contained relative to 100 parts by mass of the organopolysiloxane (II). This provides: a silicone emulsion composition that gives a cured film adhering well to plastic film substrates regardless of the type, while having suitable release properties regarding adhesives; and a delamination film made by forming a cured film of the silicone emulsion composition.

摘要： The present invention is a room temperature curable resin composition comprising: as the main agent, an organic polymer in which both molecular chain terminals are sealed by a silanol group and/or a hydrolyzable silyl group; and an organic silicon compound of a specific structure having, in a molecule, an organosiloxane structure, a hydrolyzable silyl group, and a hindered amine skeleton. This resin composition produces a cured product in which the degradation over time associated with the effects of light such as UV rays can be suppressed.

Step (I): A step in which an amino group-containing silicon compound indicated by formula (2) and a carbonyl compound indicated by formula (3) are caused to react.
(R 1 -R 4 , n, and m are as described above.)
Step (II): A step in which the chlorine atom content is reduced.-
