  • Publication number: 20230167321
    Abstract: An inkjet ink for a glass substrate can enable formation of an aesthetic image with high concealability on the surface of the glass substrate. The inkjet ink disclosed here can include: an inorganic solid including an inorganic pigment that develops black and a glass frit; a monomer component having a photocuring property; and a photoinitiator. In the inkjet ink, a volume ratio of the inorganic solid in a case where an ink total volume is 100 volume% can be 35 volume% or less, a volume ratio of the inorganic pigment in the case where a total volume of the inorganic solid is 100 volume% can be 15 volume% or more and less than 90 volume%, and a volume ratio of the inorganic pigment to the photoinitiator can be 6 times or less.

  • Publication number: 20230159377
    Abstract: An inkjet ink for a glass substrate can enable formation of an aesthetic image with high concealability on the surface of the glass substrate. The inkjet ink disclosed here can include: an inorganic solid including an inorganic pigment that develops a color except for black and a glass frit; a monomer component having a photocuring property; and a photoinitiator. In the inkjet ink, a volume ratio of the inorganic solid in a case where an ink total volume is 100 volume % can be 35 volume % or less, a volume ratio of the inorganic pigment in the case where a total volume of the inorganic solid is 100 volume % can be 15 volume % or more and less than 90 volume %, and a volume ratio of the inorganic pigment to the photoinitiator can be 11 times or less.

  • Publication number: 20220089893
    Abstract: Inkjet ink disclosed herein, usable for at least a transfer sheet suitable for an inorganic substrate, contains an inorganic solid content and a photocurable monomer component. The monomer component contains at least a monofunctional acrylate-based monomer, a monofunctional N-vinyl compound monomer, and a polyfunctional vinylether-based monomer. With respect to 100% by mass as the total weight of the monomer component, the monofunctional acrylate-based monomer is contained at a weight ratio of 40% by mass to 96% by mass, the monofunctional N-vinyl compound monomer is contained at a weight ratio of 2% by mass to 20% by mass, and the polyfunctional vinylether-based monomer is contained at a weight ratio of 2% by mass to 40% by mass.

  • Publication number: 20220017761
    Abstract: The inkjet ink disclosed herein includes an inorganic solid portion including an inorganic pigment and glass and a monomer component having a photocurability. The ink is configured such that a volume of the inorganic solid portion when a total volume of the inkjet ink is 100 vol % is 30 vol % or less, and a volume of the glass when the total volume of the inorganic solid portion is 100 vol % is 78 vol % or more.
