It is an object of the present technology to overcome the disadvantages of conventional chlorination of a copper phthalocyanine which produces copper phthalocyanine, wherein the number of chlorines is less than than or equal to 4. The pigments described herein contain less chlorine than standard commercial grades of tetrachlorinated (or greater) copper phthalocyanine pigments while achieving similar color space, chromaticity, fastness properties, and color travel in automotive waterborne and solvent borne systems. The inventive pigments are more advantageous from a toxicity and environmental perspective, and allow the manufacturer to produce pigments in a safe and economical manner.

The present invention provides a color photoresist composition, including: 5-8 parts by weight of a pigment; 5-8 parts by weight of an alkali soluble resin; 5-8 parts by weight of a phthalocyanine semi-sandwich dye; 0.2-0.6 parts by weight of a photoinitiator; 70-85 parts by weight of a photoresist solvent; and 0.1-0.2 parts by weight of an additive.

The present invention provides a color photoresist composition, based on 100 parts by weight of the color photoresist composition, including: 5-10 parts by weight of a pigment dispersion; 5-8 parts by weight of a binder resin; 5-8 parts by weight of a sandwich type phthalocyanine compound dye; 0.3-0.8 parts by weight of a photoinitiator; 70-85 parts by weight of a photoresist solvent; and 0.1-0.2 parts by weight of an additive.

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.

The present technology is directed to pigment compositions having a pure, or substantially pure, crystal form, containing less chlorine than standard tetrachlorinated copper phthalocyanine pigments, while giving similar color space, chromaticity, fastness properties, and color travel in automotive waterborne and solvent borne systems. These pigments are more advantageous from a toxicity and environmental perspective, and allow the manufacturer to produce pigments in a safe and economical manner.

A composition includes: an infrared absorbing pigment; an acid or a base that undergoes neutralization or a salt interchange reaction with the infrared absorbing pigment; an acidic or basic resin; and a solvent, in which in a case where the acid is included, the acidic resin is included, in a case where the base is included, the basic resin is included, and in a case where a pKa of the acid is represented by pKa.sup.1A, a conjugate acid pKa of the base is represented by pKa.sup.1B, a pKa of the acidic resin is represented by pKa.sup.2A, and a conjugate acid pKa of the basic resin is represented by pKa.sup.2B, any one of the following Expression A or Expression B is satisfied.

pKa.sup.1A>pKa.sup.2AExpression A

pKa.sup.1B<pKa.sup.2BExpression B

The present invention relates to a colorant, a colored resin composition comprising the colorant, and a color filter prepared using the colored resin composition. A novel reddish yellow pigment may be used in combination with a green pigment and a yellow pigment in order to reduce the imbalance of the intramolecular polarization of the green pigment and/or the yellow pigment in the colorant. As a result, a color filter comprising a colored layer in which a light leakage phenomenon, caused by an electric field distortion, is reduced.
