Patent ID: 8003736

Claim:
A silicon-containing compound represented by general formula (1): wherein R a , R b , R c , R d , R e , R f , and R g , which may be the same or different, each represent a saturated aliphatic hydrocarbon group having 1 to 12 carbon atoms or an aromatic hydrocarbon group optionally substituted with a saturated aliphatic hydrocarbon group and having 6 to 12 carbon atoms, provided that R e and R f do not simultaneously represent a saturated aliphatic hydrocarbon group having 1 to 12 carbon atoms; Y represents an alkylene group having 2 to 4 carbon atoms; Z represents a hydrogen atom or an alkenyl or alkynyl group having 2 to 4 carbon atoms; K represents a number of 2 to 7; T represents a number of 1 to 7; the unit recurring T times and the unit recurring (K-T) times may be bonded to each other blockwise or randomly; P represents a number of 0 to 3; M and N represent numbers selected such that N:M ranges from 1:1 to 1:100, that all M's and N's total at least 15, and that the silicon-containing compound represented by general formula (1) has a mass average molecular weight of 3,000 to 1,000,000; and the unit recurring M times and the unit recurring N times may be bonded to each other blockwise or randomly.
