Title:
イソシアネート基含有ウレタンプレポリマー及び樹脂粒子の製造方法
Document Type and Number:
Japanese Patent JP7084453
Kind Code:
B2
Abstract:
To provide resin particles which achieve both low temperature fixability and hot off-set resistance and are excellent in glossiness and heat-resistant storage stability, and an isocyanate group-containing urethane prepolymer for obtaining the resin particles.SOLUTION: An isocyanate group-containing urethane prepolymer is obtained by reacting polyester polyol (c), an isocyanate component (d), and an amine compound and/or water, in which the (c) contains monool (a1) and/or a monocarboxylic acid (b1), diol (a2) and a dicarboxylic acid (a2), and triol (a3) and/or a tricarboxylic acid (b3) as constituent monomers, and based on the total molar number of the constituent monomers of (c), a ratio of the total molar number of (a1) and (b1) is 0.1-5.0 mol%, a ratio of the total molar number of (a2) and (b2) is 92.0-99.89 mol%, and a ratio of the total molar number of (a3) and (b3) is 0.01-3.0 mol%.SELECTED DRAWING: None
