<p>PROBLEM TO BE SOLVED: To solve problems in which a conventional pearl ink is poor in flowability and defective in transfer and often causes piling when a printing target is heat-sensitive paper even if flowability is imparted to ink by lowering viscosity of ink and excessive lowering of the viscosity causes scattering of ink or stain of a ground. SOLUTION: In this pearl ink, curing is made possible by irradiation of ionizing radiation and the viscosity is specified to 2,000 to 80,000 cP. As a result, the ink can suitably be used as ink for heat-sensitive paper and stable printing free from defect is realized to provide a printed matter.</p> |
