Zusammenfassung:PROBLEM TO BE SOLVED: To provide a thermosetting white ink composition capable of giving a cured product having excellent reflectivity to sunlight, in particular to infrared light, and being prevented from deterioration in the reflectivity even when exposed to a severe natural environment for a long period; and a reflection sheet having a cured coating of the thermosetting white ink composition.SOLUTION: The thermosetting white ink composition containing no photopolymerization initiator includes: (A) a thermosetting compound having two or more unsaturated groups in one molecule; (B) a compound having at least one amino or imino group in one molecule; and (C) a rutile titanium oxide with average primary particle diameter of ≥0.5 μm.
