摘要： 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.
