Further, as described above, the polyether-modified silicone compounded in the present composition is a polyether-modified silicone represented by the following formula (I) [hereinafter also referred to as modified silicone (I)].

[0018]

[Chemical 3] In the formulas, A is a methyl group, a phenyl group, and the general _{formula: -C 3 H 6 O (C} 2 H 4 O) a (C 3 H 6 O) b R '(II) ( wherein, R 'Is a hydrogen atom, an acyl group and 1 carbon atom
