    • The object is to provide a polyimide ink composition having good printing properties and good continuous printing properties, which composition can be dried at a low temperature of not higher than 220° C., and which composition gives a coating film, after being dried, having excellent dimensional stability, heat resistance, low modulus of elasticity, flexibility, resistance to warping, chemical resistance, adhesiveness with substrates, and plating resistance. This object is accomplished by a polyimide ink composition for printing, comprising a mixed solvent containing an benzoic acid ester solvent and a glyme solvent, and a polyimide soluble in the mixed solvent; wherein the polyimide is obtained by polycondensing a polyimide oligomer with a tetracarboxylic dianhydride component(s) and/or a diamine component(s) having no siloxane bond in molecular skeleton thereof, the polyimide oligomer being prepared by polycondensing a tetracarboxylic dianhydride component(s) and a diamine component(s) having siloxane bonds in molecular skeleton thereof in the presence of a base catalyst(s), or a mixed catalyst including a lactone(s) and/or an acidic compound(s) and a base(s); the content of the diamine component(s) having siloxane bonds based on the total diamine components being 15 to 85% by weight.
    • 本发明的目的是提供具有良好的印刷性和良好的连续印刷性的聚酰亚胺油墨组合物,该组合物可以在不高于220℃的低温下干燥。 干燥后的涂膜具有优异的尺寸稳定性,耐热性,低弹性模量,柔软性,耐翘曲性,耐化学性,与基材的密合性,耐电镀性。 该目的通过用于印刷的聚酰亚胺油墨组合物来实现,所述聚酰亚胺油墨组合物包含含有苯甲酸酯溶剂和甘醇二甲醚溶剂的混合溶剂以及可溶于该混合溶剂中的聚酰亚胺; 其中所述聚酰亚胺是通过将聚酰亚胺低聚物与四羧酸二酐组分和/或其中不含硅氧烷键的二胺组分缩聚在其分子骨架中而获得的,所述聚酰亚胺低聚物通过缩聚四羧酸二酐组分, 和在碱催化剂存在下,或者包含内酯和/或酸性化合物和碱的混合催化剂在分子骨架中具有硅氧烷键的二胺组分, ; 基于全部二胺组分的具有硅氧烷键的二胺组分的含量为15至85重量%。
