A novel organosilicon compound is provided as an organosilicon compound containing a ²-ketoester structure that has minimal volatile components and generates a minimal amount of alcohol when used as a component within all manner of treatment agents. The organopolysiloxane is represented by an average composition formula shown below:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ Y a R 1 b R 2 c Si(OR 3 ) d (OH) e O (4-a-b-c-d-e)/2 €ƒ€ƒ€ƒ€ƒ€ƒ(1)
(wherein Y represents an organic group containing a ²-ketoester group that may be at least partially enolized, R 1 represents a monovalent hydrocarbon group that may optionally include a functional group such as a mercapto group, an epoxy group or a (meth)acryloyloxy group, R 2 represents a monovalent hydrocarbon group that contains no functional groups, R 3 represents a monovalent hydrocarbon group, and a, b, c, d and e are numbers that satisfy 0.01 ‰¤ a ‰¤ 1, 0 ‰¤ b < 1, 0 ‰¤ c ‰¤ 2, 0 ‰¤ d ‰¤ 2, and 0 ‰¤ e ‰¤ 1 respectively, provided that 2 ‰¤ a+b+c+d+e ‰¤ 3). |
