A composite nanomaterial of ZnO impregnated by, e.g., a green copper phthalocyanine compound (CuPc) can be an efficient solar light photocatalyst for water remediation. The composite may include hollow shell microspheres and hollow nanospheres of CuPc-ZnO. CuPc may function as a templating and/or structure modifying agent, e.g., for forming hollow microspheres and/or nanospheres of ZnO particles. The composite can photocatalyze the degradation of organic pollutants such as crystal violet (CV) and 2,4-dichlorophenoxyacetic acid as well as microbes in water under solar light irradiation. The ZnO-CuPc composite can be stable and recyclable under solar irradiation.

Provided is a composition which has excellent temporal stability and excellent spectral characteristics, and with which a film with suppressed defects can be formed. The composition includes a coloring agent represented by Formula (1) and a curable compound, in which R.sup.1 to R.sup.4 each independently represent a substituent, R.sup.5 represents an aliphatic hydrocarbon group, R.sup.11 to R.sup.15 each independently represent a hydrogen atom or a substituent, and Y.sup.1 and Y.sup.2 each independently represent a hydrogen atom or a substituent. However, at least one of R.sup.11, R.sup.12, R.sup.13, or R.sup.14 is a substituent or each of R.sup.11 to R.sup.15 is a hydrogen atom.

A blue curable resin composition includes a colorant (A), a resin (B), a polymerizable compound (C) and a polymerization initiator (D). The colorant (A) includes two or more pigments each having a phthalocyanine backbone. The blue curable resin composition has relatively low in Bx and is high in intensity in an xy chromaticity diagram of an XYZ color system. A color filter may be formed from the blue curable resin composition. The blue curable composition may be also used in a display device.

The present invention relates to modified proppants and methods of using the modified proppants that use metal ligand tracers to characterize subterranean fluid flow. The metal and ligands are best chosen to be a strongly-coordinating, chelating ligand with a functional group for the chosen flow environment.
