Description
組成物に流動性を与えるために必要な溶媒量を低減するために、1分子当たりの炭素数に対する水酸基の比率が8%以上であって、固体状もしくは揮発性が水と同じか水よりも低い液状であり、水溶性もしくは水分散性の化合物を含有し、
前記化合物は600分子量以下の低分子ポリアルキレングリコールから選択される1つ以上のものであることを特徴としている。
液状の化合物を用いる場合は、その化合物の揮発性が水と同じか水よりも低いものを用いることで、組成物が型に充填されるまでの過程で、組成物中の溶媒量の変動を抑制できる。ちなみに、水の20℃での蒸気圧は2300Paであることから、同一温度で比較したときの蒸気圧が水の蒸気圧以下である液状の化合物を用いれば良い。
実施例1〜11および比較例1〜6では、下記表1に記載の各化合物を添加した組成物を調合し、これらの化合物未添加の場合と比較して、組成物に流動性を与えるために必要な最小水分量の低減効果の有無について評価した。なお、表1に示す実施例の化合物は全て水溶性である。
(実施例12、13および比較例7)
