The invention features organic photoreceptors that include a charge transport compound having the formula:

Organophotoreceptors for electrophotography featuring novel charge transport compounds based upon hydroxy-functional compounds

Radiation-sensitive organo-halogen compounds that have a photo-labile halomethyl-1,3,5-triazine moiety and a polymeric moiety within the same molecule. The compounds of this invention are comprised of a polymeric moiety having attached or incorporated within its structure at least one 1,3,5-triazine nucleus, said triazine nucleus having at least one halomethyl substituent attached to a carbon atom of the triazine nucleus. These compounds are capable of being stimulated by actinic radiation at wavelengths of from about 250 to about 900 nanometers to generate free radicals and/or acids. The compounds of this invention are useful as photoinitiators in free radical polymerization reactions, oxidation-reduction reactions, or reactions sensitive to acid, and they also exhibit the capability to crosslink upon exposure to light.

Polymers containing halomethyl-1,3,5-triazine moieties

Radiation-sensitive organo-halogen compounds having a photo-labile halomethyl-1,3,5-triazine moiety and at least one polymerizable moiety within one molecule is provided. The compounds of this invention have at least one halomethyl substituent attached to a carbon atom of the triazine moiety and at least one polymerizable monomeric moiety attached to another atom of the triazine moiety. The compounds of this invention can be used to prepare polymers having 1,3,5-triazine substituents attached thereto. The compounds of this invention are good photoinitiators, and compositions containing them can be used in printing, duplicating, copying, and other imaging systems. The compounds of this invention are capable of stimulation by actinic radiation at a wavelength of about 250 to 900 nanometers to generate free radicals.

Halomethyl-1,3,5-triazines containing a monomeric moiety

A fluorescent ionophoric compound comprises a cryptand portion and a coumarin portion substituted at the 3-position with an electron withdrawing or polarizable group. The compound, which exhibits good photostability, can be incorporated into cation-sensing composite structures useful in biological and environmental testing, which can be used with conventional glass optics, by means of convenient points of covalent attachment.

Cation-sensing composite structure and compounds for use therein

Radiation-sensitive organo-halogen compounds having a photo-labile halomethyl-1,3,5-triazine moiety and at least one amine-containing moiety within one molecule. The compounds serve the dual purpose of photoinitiation and polymerization acceleration, thereby eliminating the need for the use of two separate compounds. The compounds of this invention are good photoinitiators, and compositions containing them are useful in printing, duplicating, copying, and other imaging systems.

Radiation-sensitive organo-halogen compounds having a photo-labile halomethyl-1,3,5-triazine moiety and at least one sensitizer moiety within one molecule. The compounds of this invention are good photoinitiators, and compositions containing them can be used in printing, duplicating, copying, and other imaging systems.

Halomethyl-1,3,5-triazines containing a sensitizer moiety

Radiation-sensitive organo-halogen compounds having a photo-labile halomethyl-1,2,5-triazine moiety and at least one photoinitator moiety within one molecule. The compounds of this invention are good photoinitiators, and compositions containing them can be used in printing, duplicating, copying, and other imaging systems. The compounds of this invention eliminate the need for a combination of photoinitiators in a photocurable or photopolymerizable composition.
