The present invention provides a stretchable film having excellent stretchability and strength and excellent water repellency on the surface of the film, a method for forming the stretchable film, an urethane resin used in the stretchable film, and a material for the urethane resin Of silicon compounds. The silicon-containing compound represented by the following formula (1). [Chem 1] In the formula, R 1 , R 2 , R 3 , R 4 , R 5 , and R 6 are linear, branched, cyclic alkyl, phenyl, 3,3,3- Trifluoropropyl, or a group represented by-(OSiR 7 R 8 ) n -OSiR 9 R 10 R 11 . R 7 , R 8 , R 9 , R 10 , R 11 and R 1 to R 6 have the same meaning, and n is an integer in the range of 0 to 100. A is a linear or branched alkylene group having 3 to 6 carbon atoms, and m is an integer in the range of 1 to 3. |
