Composition and film

Abstract

A first object of the present invention is to provide a composition that is excellent in water stopping ability, embedding property, and maintainability of an embedded state. In addition, a second object of the present invention is to provide a film formed of the above-mentioned composition. The composition of the present invention is a composition including a polyurethane formed from a polyol containing a polyoxyalkylene structure and a polyisocyanate; and particles, in which the composition has an Asker C hardness of 5 or less, a ratio of a loss elastic modulus G″ to a storage elastic modulus G′ at a temperature of 25° C., a frequency of 1 Hz, and a strain of 0.1% of 0.400 or more, and a ratio of the storage elastic modulus G′ at a temperature of 25° C., a frequency of 1 Hz, and a strain of 10% to the storage elastic modulus G′ at a temperature of 25° C., a frequency of 1 Hz, and a strain of 0.1% of less than 0.900.
