Red-Shifted Triazine Ultravioletlight Absorbers
US Patent:
6800757, Oct 5, 2004
Filed:
Sep 27, 2001
Appl. No.:
09/964919
Inventors:
Ram Baboo Gupta - Stamford CT
Hargurpreet Singh - Ansonia CT
Russell C. Cappadona - Norwalk CT
Hargurpreet Singh - Ansonia CT
Russell C. Cappadona - Norwalk CT
Assignee:
Cytec Technology Corp. - Wilmington DE
International Classification:
C07D25112
US Classification:
544211, 544213, 544217, 544219, 252380, 524100
Abstract:
The present invention relates to novel red-shifted UV absorbers comprising 1,3,5-triazine structures containing a 2-naphthol-derived substituent. The present invention also relates to a method for stabilizing a material by incorporating into such material, e. g. , organic material, the novel red-shifted triazine compounds in an amount effective to stabilize the material against the effects of actinic radiation.
Phenyl Ether-Substituted Hydroxyphenyl Triazine Ultraviolet Light Absorbers
US Patent:
6855269, Feb 15, 2005
Filed:
Nov 9, 2001
Appl. No.:
10/039933
Inventors:
Ram Baboo Gupta - Stamford CT, US
Hargurpreet Singh - Ansonia CT, US
Russell C. Cappadona - Norwalk CT, US
Hargurpreet Singh - Ansonia CT, US
Russell C. Cappadona - Norwalk CT, US
Assignee:
Cytec Technology Corp. - Wilmington DE
International Classification:
C09K003/00
US Classification:
25218213, 252380, 252384, 544180, 544215, 544216, 544217, 544218
Abstract:
This invention relates generally to phenyl ether substituted triazines compounds and compositions containing same and their use to protect against degradation by environmental forces. A method for stabilizing a material by incorporating such triazines is also disclosed.
Non-Yellowing Ortho-Dialkyl Aryl Substituted Triazine Ultraviolet Light Absorbers
US Patent:
6867250, Mar 15, 2005
Filed:
Oct 30, 2000
Appl. No.:
09/698368

Assignee:
Cytec Technology Corp. - Wilmington DE
International Classification:
C08K005/34
US Classification:
524100, 544180, 544214, 544215, 544216
Abstract:
The invention relates generally to pyrimidines and triazines ultraviolet light absorbers containing a phenolic aromatic group(s) and a non-phenolic aromatic group(s) and the use thereof to protect against degradation by environmental forces, inclusive of ultraviolet light, actinic radiation, oxidation, moisture, atmospheric pollutants, and combinations thereof. The new class of pyrimidines and triazines includes two (one) non-phenolic aromatic groups with hydrocarbyl groups that are ortho to each other and one (two) resorcinol or substituted resorcinol group attached to a triazine or pyrimidine ring. The pyrimidines and triazines may be included in a polymeric structure. A method for stabilizing a material by incorporating the novel pyrimidines and triazines is also disclosed.

Russell Cappadona - Norwalk CT, US
Hargurpreet Singh - Ansonia CT, US
Russell Cappadona - Norwalk CT, US
International Classification:
C07D417/02
C07D413/02
C 07D 4 3/02
C07D413/02
C 07D 4 3/02
US Classification:
544/211000, 544/212000, 544/060000, 544/113000
Abstract:
This invention relates to a novel, efficient, economic and general-purpose process for isolating monophenolic-bisaryl triazine compounds from polyphenolic-triazines compounds and other impurities. More specifically, this invention relates to a process for isolating the monophenolic-bisaryl triazine compounds by contacting it with a base, an alcohol or a hydrocarbon solvent.
