A dispersion which contains a dispersant and particles selected from among metal particles and metal oxide particles, and which is characterized in that: the dispersant has a chemical structure that is able to be bonded or adsorbed to the particles; and the dispersant contains a low-molecular-weight dispersant that has at least one peak within a molecular weight region of 31 or more but less than 1,000 in the molecular weight distribution curve in terms of polyethylene glycol as determined by gel permeation chromatography and a high-molecular-weight dispersant that has at least one peak within a molecular weight region of 1,000 or more but 40,000 or less in the above-described molecular weight distribution curve.
一种分散剂,它含有一种分散剂和选自金属颗粒和金属氧化物颗粒的颗粒,其特征在于分散剂的化学结构能与颗粒结合或吸附;分散剂含有一种低分子量分散剂,该分散剂在凝胶渗透色谱法测定的聚乙二醇分子量分布曲线中,至少有一个峰值在 31 或以上但小于 1,000 的分子量区域内;还含有一种高分子量分散剂,该分散剂在上述分子量分布曲线中,至少有一个峰值在 1,000 或以上但小于 40,000 的分子量区域内。
