Title:
可逆熱変色性紫外線硬化型インキ及びそれを用いた可逆熱変色性積層体
Document Type and Number:
Japanese Patent JP4303396
Kind Code:
B2
Abstract:
This invention provides a reversibly thermochromic ultraviolet ray-hardening type ink having good color change sensitivity and excellent light resistance and fastness, and a reversibly thermochromic laminate produced using the same. The present invention also provides a reversibly thermochromic laminate produced by forming a reversibly thermochromic layer on a support using the same. The ink comprises: (1) a microencapsulated pigment comprising a reversibly thermochromic composition comprising (A) an electron-donating compound, (B) an electron-accepting compound and (C) a color change temperature-controlling agent which controls color reaction generation temperature of the former two compounds; and (D) a light resistance-providing agent represented by a specific formula, and (2) a photo-polymerizable composition comprising an ultraviolet ray absorbent, a reactive oligomer, a reactive monomer, and an acylphosphine oxide photo-polymerization initiator, wherein said microencapsulated pigment is dispersed in said photo-polymerizable composition.
