Problems solved by technology

[0011] However, the above-mentioned color-changing material composition has the following problems: when the color-changing film containing a coumarin-based pigment as a blue-light-absorbing pigment is continuously irradiated by blue light emitted by an organic EL, the coumarin-based pigment decomposes, thereby failing to fully absorb the blue light from the light source. for emission and poor color change performance, or pigments depending on the resin composition due to deposition in storage renders the film unusable

Abstract

Provided are novel hetero-polycyclic compounds having a specific structure, color-changing material compositions comprising (A) a fluorescent coloring matter comprising at least one of the hetero-polycyclic compounds described above and (B) a binder material, color-changing films comprising the above hetero-polycyclic compounds, coloring matters comprising the above hetero-polycyclic compounds, and pigments or dyes comprising the hetero-polycyclic compounds described above, and provided are color-changing material compositions which are not deteriorated in a color-changing performance even after used for long time and which are prevented from being unusable due to deposition of coloring matters during storage and color-changing films produced by using the same, and novel hetero-polycyclic compounds, coloring matters and pigments or dyes which actualize them.

Description

Background of the invention [0001] This application relates to novel heteropolycyclic compounds, and pigments, pigments or dyes prepared therefrom, color-changing material compositions and color-changing films, and in particular to color-changing material compositions whose color-changing performance does not change even after prolonged use Damage occurs and prevents unusability due to pigment deposition during storage, and also relates to color-changing films prepared therefrom, as well as novel heteropolycyclic compounds, pigments and pigments or dyes for realizing them. [0002] related technology [0003] So far, in addition to being used as dyes and pigments, organic fluorescent pigments are also used in a wide range of fields as pigments for fluorescent conversion films in various display devices, and as pigments for dye lasers, anti-copying, solar energy conversion and Fluorescent film in a greenhouse. [0004] It is urgently desired that the organic fluorochromes use...
