International Classification:

B29D 2300
C08G 6944

US Classification:

428 3692

Abstract:

This invention provides certain blue substituted 1,4-bis(2,6-dialkylanilino) anthraquinones in combination with selected red anthraquinone and anthrapyridone (3H-dibenz[f,ij] isoquinoline-2,7-dione) compounds which provide a toner system useful in imparting a desirable neutral to slightly blue hue to polyesters having a yellow appearance. The thermally stable colored compounds can have polyester reactive groups and are preferably incorporated into the polyester polymer structure during polymerization.

International Classification:

C08K 534

US Classification:

524 88

Abstract:

Provided is a method for tagging thermoplastic containers using near infrared fluorescing compounds or copolymerized residues readily capable of detection. Also provided is a method for identifying a thermoplastic container. Also provided are thermoplastic polymer compositions comprised of the near infrared fluorescing compounds or residues and articles comprised of such compositions. Also provided are new compounds useful as near infrared fluorophoric markers in the practice of this invention. The methods, compositions, and compounds of the present invention thus provide a total system useful for marking, for identification purposes, the various classes of thermoplastic wastes, so that they can be identified, sorted, and subsequently recycled.

International Classification:

C08K 534

US Classification:

524 88

Abstract:

The present invention relates to a container preform comprising: a polymer suitable for the production of a stretch blow molded bottle and at least one organic or metallated organic near infrared absorbing compound which absorbs at least twice as much light between about 700 nm and about 1200 nm as between about 400 mn and about 700 nm wherein said near infrared absorbing compound is present in an amount sufficient to improve reheat rate of said preform. Suitable near infrared absorbing compounds include phthalocyanines, 2,3-napthalocyanines, squaraines (squaric acid derivatives), croconic acid derivatives, substituted indanthrones and certain highly substituted anthraquinones. A process for improving the reheat rate of a container preform is also disclosed.
