摘要：A process for coating a substrate which comprises coating the substrate with asolution containing an organic solvent and

< P>(1) a diorganopolysiloxane having terminal SiC-bonded vinyl groups,

(2) an organopolysiloxane having at least 3 Si-bonded hydrogen atoms per molecule,

(3) a catalyst which promotes the addition of Si-bonded hydrogen to an aliphaticmultiple bond; and optionally

(4) an agent which delays or retards the addition of Si-bonded hydrogen to analiphatic multiple bond at room temperature,

(5) a diorganopolysiloxane having a viscosity of at least 10.sup.6 mPa.s at 25° C. inwhich a vinyl group is bonded to a silicon atom in 0.033 to 3.33 percent of the

diorganosiloxane units, while the other organic radicals in the diorganosiloxane units ofthe diorganopolysiloxane are free of aliphatic multiple bonds, and

(6) an organosilicon adhesive compound.

An acrylic acid ester polymer or copolymer (7) may be applied to the substratesimultaneously with or prior to the application of the solution containing components (1)

through (6) above.
