ARYLIDEN PYRAZOLONE PIGMENT, COLORING COMPOSITION, INK SHEET FOR HEAT-SENSITIVE TRANSFER RECORDING, HEAT-SENSITIVE TRANSFER RECORDING METHOD, COLOR TONER, INK FOR INKJET, AND COLOR FILTER

摘要

PPROBLEM TO BE SOLVED: To provide a new aryliden pyrazolone pigment having excellent spectral characteristic with sharp absorption, high fastness properties and high solubility to an ink and a colored composition, and to provide an ink sheet for heat-sensitive transfer recording simultaneously satisfying all of excellent color reproducibility, image storage property and transfer sensitivity, a color toner, an ink for inkjet, a color filter, and a heat-sensitive transfer recording method. PSOLUTION: The arylidene pyrazolone pigment is represented by general formula (1) (wherein RSP1/SP, RSP2/SP, RSP3/SP, RSP4/SPand RSP5/SPeach independently represents a monovalent substituent, and n represents an integer of 0-4).
