    • The present invention provides a thermosetting ink composition having excellent balance concerning screen printability capable of preventing oozing and bleeding at the time of screen printing, electric insulating reliability and adhesion with an objective for coating. The thermosetting ink composition of the invention comprises a thermosetting resin (A) having a value “a” of less than 0.60 in the following formula (1) showing the relationship between the intrinsic viscosity [η] and the absolute molecular weight M of the resin: [η]=K×Ma  (1) wherein K is a constant number. Since the thermosetting ink composition can prevent oozing and bleeding at the time of screen printing and an excessive amount of a filler is not used for improving the printability, it can form excellent solder resists and other protective films at low coat without decreasing the electric insulating reliability and adhesion with an objective for coating.
    • 本发明提供了一种在丝网印刷时能够防止渗出和渗色,电绝缘可靠性和与涂布目的的粘合性的丝网印刷性的平衡性优异的热固性油墨组合物。 本发明的热固性油墨组合物包含在下式(1)中具有小于0.60的值“a”的热固性树脂(A),其显示了特性粘度[和eegr]与绝对分子量M之间的关系 树脂:[&eegr]] = K×Ma(1)其中K是常数。 由于热固性油墨组合物可以防止丝网印刷时的渗出和渗色,并且不会使用过量的填料来提高印刷性,所以可以在低涂层下形成优异的阻焊剂和其它保护膜,而不会降低电绝缘可靠性 以及用于涂布的粘合。
