  • Patent number: 6197851
    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.
