<p>PURPOSE: Photocurable ink composition for inkjet is provided to have excellent jetting property and photo-curability, and to form a photo-cured layer having excellent plating resistance, heat resistance, adhesion with substrate and fire retardance. CONSTITUTION: A photocurable ink composition comprises: a compound in chemical formula 1; a compound having at least one functional group selected from a group consisting of oxyranyl, oxetanyl, alkoxysilyl and hydroxyl. The viscosity at 25°C is 200 mPa·s or less. In chemical formula 1, R is a C1-100 divalent organic group. An electronic circuit board comprises a circuit on a board, and a cured layer of the photocurable composition formed on at least a part of the board and the circuit.</p> |
