  • Radiation-sensitive composition, planographic printing plate precursor, and plate-making method for planographic printing plate
    Patent number: 11370862
    Abstract: A planographic printing plate precursor includes: a support; and an image recording layer which includes a radical initiator, a radical polymerizable component, and a radiation absorption compound, and in which the image recording layer shows two or more peaks of a radical generation amount in a radical generation amount-versus-time curve after exposure to image forming radiation, in which the radical initiator includes an electron-donating radical initiator and an electron-accepting radical initiator, and the radiation absorption compound comprises a compound represented by the following Formula 1.

  • COLORING COMPOSITION, FILM, COLOR FILTER, SOLID-STATE IMAGING ELEMENT, AND IMAGE DISPLAY DEVICE
    Publication number: 20210395487
    Abstract: Provided are a coloring composition including a colorant including a green pigment, a compound A, and a resin, in an which amount of the green pigment dissolved in 100 g of propylene glycol methyl ether acetate at 25° C. is less than 0.01 g, an amount of the compound A dissolved in 100 g of propylene glycol methyl ether acetate at 25° C. is 0.01 g or more, the coloring composition includes 0.1 to 10 parts by mass of the compound A with respect to 100 parts by mass of the green pigment, and the green pigment and the compound A satisfy a relationship of “?1.0 eV?LUMOB?LUMOA?1.0 eV”; a film; a color filter; a solid-state imaging element; and an image display device. LUMOB is an energy level of a lowest unoccupied molecular orbital of the green pigment, and LUMOA is an energy level of a lowest unoccupied molecular orbital of the compound A.
