  • Publication number: 20050074480
    Abstract: The present invention relates to a process for coating a surface of a polymer film with a release coating composition to provide a release film for use in high temperature and/or high humidity conditions, which comprises coating at least one surface of the polymer film with an aqueous of from about 0.2 to about 6.0% by weight of at least one hydroxypropyl methyl cellulose having hydroxypropyl molar substitution of from 0 to about 0.82 and from about 1% to about 35% by weight of alcohol to provide a coating weight of at least about 0.004 lb/ream per side and drying the coated film to set the coating. Also disclosed is a release polymer film coated on at least one surface with a composition comprising from about 0.2 to about 6.0% by weight of at least one hydroxypropyl methylcellulose having hydroxypropyl molar substitution of from 0 to about 0.82 and the coating weight is at least about 0.004 lb/ream.

  • Patent number: 6455675
    Abstract: The invention relates to the molecular cloning and expression of a gibberellin (GA) 20-oxidase gene and its use, for example in transgenic plants. Aspects of the invention include recombinant DNA which encodes a polypeptide exhibiting GA 20-oxidase activity, a recombinant polypeptide exhibiting GA 20-oxidase activity, and transgenic plants which express a GA 20-oxidase gene or reverse GA 20-oxidase sequences.
    Type: Grant
