摘要:
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.
