This application discloses amber colored polyesters suitable for packaging food and beverages. The amber polyester compositions provide excellent blockage of UV and visible light over the wavelength ranges of from about 320-550 nm, rendering them suitable for packaging materials sensitive to ultraviolet and visible light over this wavelength range, particularly beer.

Amber polyester compositions and container articles produced therefrom

A pigment composition includes a crystalline thermoplastic polyester resin having residues of at least one dicarboxylic acid and a near-infrared fluorescing compound having a fluorescence between about 650 nm to about 2500 nm associated with the crystalline thermoplastic polyester, wherein the polyester has an intrinsic viscosity (IV) of less than about 0.37. A preferred polyester is polybutylene terephthalate. Another aspect is a method for providing a detectable or identifiable marking that is invisible to the unaided eye on a surface of a substrate is also provided. The method includes the steps of applying to the surface a marking composition comprising a suitably compatible marking fluid containing the fluorescent pigment composition. The near infrared fluorescing pigment composition is useful in letterpress, flexographic and gravure printing applications.

Pigment particles for invisible marking applications

The present invention relates to a low-irritation anesthetic and antiseptic mouth rinse. The mouth rinse is freeze-thaw stable and is prepared using polyethylene glycol having a number average molecular weight of 200 to 300 which have been found to be compatible with local anesthetics and other ingredients commonly used in mouth rinses.
