<p><P>PROBLEM TO BE SOLVED: To provide an active light ray-curable resist ink combining: excellent adhesion to a slight-adhesive substrate, a circuit in which a conductive paste on the slight-adhesive substrate is printed, or a circuit produced by etching a copper foil; insulation; printing properties; cold-resistant flexibility; heat resistance; moisture resistance; and the like. <P>SOLUTION: The active light ray-curable resist ink is an active light ray-curable resin composition essentially comprising: 100 wt.pts. of (A) an active light ray-polymerizable polymer containing as a copolymer component, a polyester; 20 to 400 wt.pts. of (B) an inorganic filler; 1 to 200 wt.pts. of (C) a bifunctional active light ray-polymerizable compound represented by the formula: (where R<SP>1</SP>is a 1C-9C aliphatic hydrocarbon group which may be branched; R<SP>2</SP>is hydrogen or a methyl group; and m is an integer of 1 to 9); and 20 to 360 wt.pts. of (D) a monofunctional active light ray-polymerizable compound having in the molecule thereof, an aromatic group. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
