PURPOSE: An ink for ink jetting is provided to secure the hardening property of a film using the ink and the discharging property of the ink, and to use the ink as a resist for manufacturing an electronic circuit board. CONSTITUTION: An ink for ink jetting is marked with chemical formula 1, and contains a resin with the weight average molecular weight of 1,000~8,000. In the chemical formula 1, X is a component of a radically polymerizable monomer. M is an integer larger than 1. The viscosity of the ink in 25 deg C is 2~200 centipoises. |
