Filed:

May 3, 2001

Appl. No.:

09/848014

Inventors:

Anunay Gupta - Boontoon NJ
David Devore - Nyack NY
John James McNamara - Putnam Valley NY
Alessandro Zedda - Basel, CH

Assignee:

Ciba Specialty Chemicals Corporation - Tarrytown NY

International Classification:

C08K 506

US Classification:

524376, 524397

Abstract:

Polyolefin films having incorporated therein a compound of the formula CH CH (CH CH ) CH CH (OCH CH ) OH, where a is 9 to 25 and b is 1 to 10, exhibit superior long lasting fog resistance. The polyolefin films are useful as packaging film for moist products and as a greenhouse film for agricultural applications.

Filed:

Jul 8, 2004

Appl. No.:

10/887201

Inventors:

Andrew J. Leggio - Franklin Square NY, US
Mervin G. Wood - Mobile AL, US
Joseph Suhadolnik - Yorktown Heights NY, US
John J. McNamara - Putnam Valley NY, US
Ying Dong - Tarrytown NY, US

Assignee:

Ciba Specialty Chemicals Corporation - Tarrytown NY

International Classification:

D06P 3/79

US Classification:

8557, 8513

Abstract:

A process for dyeing or printing an article comprising a hydrophobic polymer, wherein the hydrophobic polymer is brought into contact with a condensation polymer obtained by condensation of at least one poly-hydroxyl-mono-carboxylic acid, prior to or simultaneously with the treatment of the article with a color imparting compound, with the proviso that the condensation polymer is not terminated with lipophilic groups. The process provides dyed articles with good fastness properties.

Appl. No.:

10/378841

Inventors:

Anthony Verdes - Brick NJ, US
Klaus Oesterheld - Middletown NJ, US
John R. McNamara - Jackson NJ, US

Assignee:

Dialight Corporation - Farmingdale NJ

International Classification:

F21V 7/04

US Classification:

362555, 362581, 362616, 362800

Abstract:

A multi-level optical device that includes a housing. Further, a multi-level lightpipe is placed in the housing and includes at least two paths for passing light. A lightpipe barrier can optionally be placed between the at least two paths in the multi-level lightpipe, to provide enhanced separation between the light passing through the two paths. Further, a plurality of light emitting diodes (LEDs) are provided in the housing. Respective ones of the plurality of LEDs provide light input into a respective one of the paths of the multi-level lightpipe. The multi-level lightpipe can take the form of a bi-level prism, and the plurality of LEDs may be multi-color LEDs. A light-bleeding preventing device can be positioned between the at least two paths in the multi-level lightpipe. The multi-level lightpipe can also include plural multi-level lightpipes arranged in a row to create a matrix of output light signals.

International Classification:

C08K005/34

US Classification:

524100000

Abstract:

Polyolefin fibers and filaments, and fabrics made therefrom, are rendered dyeable via a combination of dyeability additives. The dyeability additive combination comprises at least one compound selected from the group consisting of the polyamides, copolyamides and polyetherpolyamides and at least one ethylene vinyl acetate. The dyed polyolefin fibers and fabrics are rendered light stable via the use of a combination of stabilizers, which comprises at least one compound selected from the group consisting of the ultraviolet light stabilizers and at least one compound selected from the group consisting of the hindered amine light stabilizers. The ultraviolet light stabilizers are for example hydroxyphenylbenzotriazoles or tris-aryl-s-triazines. The hindered amine light stabilizers are for example of high molecular weight, for instance greater than 1000 g/mol. The dyes are for example anthraquinone blue dyes, anthraquinone red dyes, diazo red dyes or nitro yellow dyes.
