PROBLEM TO BE SOLVED: To provide a resin material securing a wiring conductivity for intaglio printing printed by adopting a general intaglio plate-forming process without adopting a special process such as surface modification or the like.SOLUTION: An intaglio printing resin material has elasticity after hardening. The hardened substance of the resin material has a weight increase rate after immersion in butyl carbitol acetate at 25°C for 24 hrs. of 1.02-4.3% and a hardness decreasing rate of 3.5% or lower. Besides, the hardened substance has the weight increase rate after immersion in water at 25°C for 24 hrs. of 5.75-19.8% and the hardness decreasing rate of 16.4% or higher. The value obtained by dividing the weight increase rate after immersion in the solvent by that after immersion in water is 0.05 to 1.02, and the value obtained by dividing the hardness decreasing rate after immersion in the solvent by that after immersion in water is 0.14 or less.SELECTED DRAWING: Figure 1 |
