Preferred Components: The polysiloxane (Ia) is selected from H2C=CH-Si(CH3)2-O-(Si(CH3)2-O)820-Si(CH3)2-CH=CH2; H2C=CH-Si(CH3)2-O-(Si(CH3)2-O)850-Si(CH3)2-CH=CH2; H2C=CH-Si(CH3)2-O-(Si(CH3)2-O)870-Si(CH3)2-CH=CH2; H2C=CH-Si(CH3)2-O-(Si(CH3)2-O)880-Si(CH3)2-CH=CH2; H2C=CH-Si(CH2CH3)2-O-(Si(CH3)2-O)820-Si(CH2CH3)2-CH=CH2; H2C=CH-Si(CH3)2-O-(Si(CH3)2-O)850-Si(CH2CH3)2-CH=CH2; H2C=CH-Si(CH3)2-O-(Si(CH2CH3)2-O)870-Si(CH3)2-CH=CH2; or H2C=CH-Si(CH3)2-O-(Si(CH2CH2CH3)2-O)880-Si(CH3)2-CH=CH2. The second polysiloxane (Ib) is selected from H2C=CH-Si(CH3)2-O-(Si(CH3)2-O)920-Si(CH3)2-CH=CH2; H2C=CH-Si(CH3)2-O-(Si(CH3)2-O)990-Si(CH3)2-CH=CH2; H2C=CH-Si(CH3)2-O-(Si(CH3)2-O)1050-Si(CH3)2-CH=CH2; H2C=CH-Si(CH3)2-O-(Si(CH3)2-O)1160-Si(CH3)2-CH=CH2; H2C=CH-Si(CH2CH3)2-O-(Si(CH3)2-O)950-Si(CH2CH3)2-CH=CH2; H2C=CH-Si(CH3)2-O-(Si(CH3)2-O)1000-Si(CH2CH3)2-CH=CH2; H2C=CH-Si(CH3)2-O-(Si(CH2CH3)2-O)1090-Si(CH3)2-CH=CH2; or H2C=CH-Si(CH3)2-O-(Si(CH2CH2CH3)2-O)1140-Si(CH3)2-CH=CH2. The viscosity of the polysiloxane (Ia) is 5000-16000 mPa.s; and the viscosity of the polysiloxane (Ib) is 18000-40000 mPa.s. The polysiloxane (II) is selected from H2C=CH-Si(CH3)2-O-Si(-0-Si(CH3)2-CH=CH2)3; H2C=CH-Si(CH2CH3)2-O-Si(-0-Si(CH2CH3)2-CH=CH2)3; H2C=CH-Si(CH3)2-O-Si(-0-Si(CH3)2-CH=CH2)2(-0-Si(CH2CH3)2-CH=CH2); or H2C=CH-Si(CH2CH3)2-O-Si(-0-Si(CH2CH3)2-CH=CH2)2(-0-Si(CH2CH2CH3)2-CH=CH2). The hydro-group-containing polysiloxane (III) has a weight average molecular weight of 200-5000, and contains 0.1-10 wt.% of trimethoxysilyl group.
