Document Type and Number:
Japanese Patent JP6905872
Kind Code:
B2
Abstract:
The present invention provides a colored resin composition which exhibits excellent contrast and heat resistance. The colored resin composition is characterized by containing a colorant and resin, theabovementioned colorant contains a compound represented by Formula (I), and the compound is a compound having an absorption maximum wavelength in the range of 500 nm to 700 nm. [In the Formula (I), ring T1 represents an aromatic hydrocarbon ring that has 6 to 20 carbon atoms and may have a substituent or an aromatic heterocyclic ring that may have a substituent. Ring T2 represents a nitrogen-containing aromatic heterocyclic ring that may have a substituent and contains N+ in atoms constituting the ring. L1 and L2 each independently represents a divalent hydrocarbon group that have 1 to 8 carbon atoms and may have a substituent. Mn+ represents an arbitrary positive ion. n represents an integer of 1 to 5.]
