Optically anisotropic films based on sulfoderivatives of 1,8-naphthoylene-1′,2′-benzimidazole are disclosed. These compounds form stable lyotropic liquid crystal systems that exhibit excellent optical properties with films that are significantly thinner that the current state of the art. The lyotropic liquid crystal systems may be deposited on substrates for use in a wide variety of commercial applications.

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.

The present invention relates to a dye of formula (I) where R1, R2, X, Y and t are each as defined in claim 1, to its preparation and to its use.

The invention pertains to a method for preparing derivatives of the pyrazolinylnaphthalic acid having the general formulawhere Ar1 and Ar2 are unsubstituted or substituted phenyl radicals bearing in the para position an alkylated or acylated oxy- or amino group, or a polynuclear aryl radical, and Ar3 is a substituted N-naphthalimid or 1,8-naphthylene-1',2'-benzimidazole. Compounds of the above general formula are high-efficient red organic luminophors and are used widely as luminescent components of dyes for plastics and liquid scintillators, in hydrogeology to study water streams, to label the chemical industry wastewaters, as laser dyes, etc.

The invention relates to a fused ring aromatic pigment and polymer material mixture, a preparation method and a downstream product thereof. According to the method, different thermoplastic polymer materials can be selected and mixed with reactants for generating fused ring aromatic pigments; by adjusting the reaction molar ratio of the raw materials and the use amounts of the raw materials in thewhole reaction system, the mixture of the reactant and the high polymer material can be extruded or kneaded to obtain the fused ring aromatic pigment and polymer material mixture in one step; and compared with the pigments, the mixture of the invention has the following characteristics that the raw material reactants of the pigment have good dispersity in the high polymer material so as to directly generate and uniformly disperse the pigment in the polymer material through extruding or kneading, the solvent is not required to be added in the extrusion or kneading process, the o-diamine compound is almost completely consumed, the obtained mixture does not need to be purified, the generation of three-waste in the traditional pigment synthesis process is avoided, the process flow is greatly simplified, and the energy consumption is reduced.
