  • Patent number: 11976199
    Abstract: There is provided a novel halogenated zinc phthalocyanine pigment for a color filter, which can form a green color filter having excellent contrast and high luminance. A halogenated zinc phthalocyanine pigment for a color filter shows, in a Raman spectrum, a peak intensity of 3.0% or more at 716±2.2 cm?1 when a peak intensity at 650±10 cm?1 is regarded as 100%.

  • Patent number: 10592150
    Abstract: A storage apparatus according to an aspect of the present invention is configured to perform a deduplication process on write data from a host. For the deduplication process, the storage apparatus calculates a feature value of write data, and records, in a management region, metadata that is a set of the feature value of the write data and information on a storage position of the write data. However, to prevent the amount of metadata stored in the management region from increasing, if write data meets a predetermined condition, the storage apparatus does not perform the deduplication process, and suppresses creation of metadata of the write data.

  • Patent number: 9873796
    Abstract: Provided are a green pigment composition for a color filter having high brightness and wide color reproduction range in a liquid crystal display, and a color filter formed including the same. A halogenated zinc phthalocyanine containing an average of 10 to 14 halogen atoms per molecule in which an average of 8 to 12 are bromine atoms and an average of 2 to 5 are chlorine atoms is used. As a result, film thickness is less than when using Pigment Green 7 and, thus, a color filter with high brightness and wide color reproduction range can be provided.
