PURPOSE: To provide the titled composition composed of a film-forming resin having carboxyl group or carboxylic anhydride group, a specific low-molecular unsaturated compound, etc., suitable as an etching resist ink for the production of a printed circuit board and applicable by dry-offset printing.
CONSTITUTION: The objective composition is produced by compounding (A) a film-forming resin having carboxyl group or carboxylic anhydride group (e.g. styrene/maleic anhydride copolymer), (B) a low-molecular unsaturated compound obtained by adding an alkylene oxide to a phenol or bisphenol which may have substituent groups and subjecting the addition product to the esterification reaction with (meth)acrylic acid, and if necessary (C) a radical polymerization initiator. The amounts of the components A and B are preferably 10W80wt% and 20W90wt%, respectively.
