Examples
example 1
[0087]Example 1 was prepared so that the first component herein is 20% by weight or more from the basis of the composition of the comparative example 1. The ratio of the second component to the fifth component herein was same as that of the Comparative Example 1. The composition had the following components and characteristics. Δ∈ of Example 1 was lager than that of Comparative Example 1. NI of Example 1 was higher than that of Comparative Example 1.
