Abstract
The present invention provides a composition containing the following components (A)-(C): (A) an alkali metal compound, (B) a polymer having an acidic dissociative group, and (C) a compound having an acidic dissociative group and an amino group, and having β of more than 0.0 and less than 1.0 as calculated by the formula (I): β={amount (mol) of alkali metal in component (A)−amount (mol) of acidic dissociative group in component (B)}/amount (mol) of acidic dissociative group in component (C).
