Patent ID: 10543695

Abstract:
A photocurable white ink composition for inkjet printing contains: a photopolymerizable compound that contains: virtually no vinyl formamide; 0.1 to 20 percent by mass of a monofunctional monomer containing an ether group relative to the total mass of the photopolymerizable component; 35 to 70 percent by mass of a monofunctional monomer containing a cyclic structure relative to the total mass of the photopolymerizable component; 5 to 40 percent by mass of a multifunctional monomer relative to the total mass of the photopolymerizable component; an acyl phosphine oxide photopolymerization initiator by 3 to 20 percent by mass relative to the total mass of the photopolymerizable component; and titanium dioxide; wherein, the viscosity of said photocurable white ink composition for inkjet printing is 100 mPa·s or less at 25° C.
