Near-infrared curable ink composition and production method thereof, near-infrared cured layer, and stereolithography

Abstract

A near-infrared curable ink composition on a predetermined substrate that has excellent adhesion to the substrate when irradiated with near-infrared rays and cured, a near-infrared curable film obtained from the near-infrared curable ink composition, and stereolithography using the near-infrared curable ink composition, and contains composite tungsten oxide fine particles as near-infrared absorbing fine particles and uncured thermosetting resin, wherein the composite tungsten oxide fine particles have a XRD peak top intensity ratio value of 0.13 or more based on a XRD peak intensity ratio value of 1 on plane (220) of a silicon powder standard sample (640c produced by NIST).
