Definitions

  • optical artifacts such as lack of interference may be observed because an interphase that is too thick often makes the index gradient fuzzy and gradual instead of sharp.
  • the multilayer optical film disclosed herein can be drawn at a ratio sufficient to impart the desired optical properties to the film without having a detrimental affect on interlayer adhesion.
  • the first diol monomer may comprise one or more diol monomers, and they may be any of those used to make polyesters for optical applications.
  • Useful diol monomers also include those having more than two hydroxyl groups, for example, triols, tetraols, and pentaols, may also be useful.
  • the first polyester may comprise less than 10 mol% soldium salt of 5-sulfoisophthalate and at least 90 mol% terephthalate; and the first diol monomers may comprise 70-75 mol% ethylene glycol and 25-30 mol% neopentylglycol.
  • the first optical layer may comprise acetates or oxides of metals selected from the group consisting of beryllium, sodium, magnesium, calcium, strontium, barium, boron, aluminum, gallium, manganese, cobalt, zinc, and antimony.
  • the first optical layer may comprise one or more phosphorus compounds such as phosphoric acid or trimethyl phosphate.
  • the first optical layer may comprise less than 0.5 wt%, or less than 0.1 wt%, of one or more catalysts and/or stabilizers.
  • the first polyester may comprise about 0.5 wt % or less of a monovalent organic salt.
  • the first optical layer may comprise a first polyester comprising a salt of 5-sulfoisophthalate, naphthalene dicarboxylate, and ethylene glycol; and the second optical layer may comprise a second polyester comprising terephthalate, ethylene glycol, and neopentyl glycol.
  • the source of sodium ion may be a monomer, e.g., sodium 5-isophthalate, and/or an inorganic or organic salt such as sodium acetate.
  • Polyester E was a copolyester in which 55 mol% of the diacid moieties result from use of naphthalene dicarboxylic acid or its esters and 45 mol% of the diacid moieties result from use of terephthalic acid or its esters, and the diol moieties result from use of a mixture of diols which includes 1,6-hexanediol.
  • Polyester J was Eastar® Copolyester 6763 commercially available from Eastman Chemical Company.
  • Eastar® Copolyester 6763 is a glycol-modified PET and is believed to have no pendant ionic groups.
  • Polyester N was SAl 15 copolyester commercially available from Eastman
  • the Control was a single layer biaxially stretched PET film having a thickness of about 120 micrometer (SCOTCHPAR from 3M Co.). Since the monolayer PET film has no internal layer interfaces, the result of this test gives the upper limit for peel strength for a polyester film detectable by this test method. A multilayer film having a peel strength identical to that of the PET monolayer film can be said to have no tendency whatsoever to delaminate within the ability of this test to detect it. The result is summarized in Table 4.
