Abstract: A system and a method are provided for matching the color of a target sample at a remote location. The system has a first computer that is operative to receive and transmit target spectral data at a first location. A second computer in the system is located at a second location remote from the first computer. The second computer is operative to receive the target spectral data or formula identifier from the first computer. The system includes a database including a plurality of data sets. Each data set has at least spectral data corresponding to standard samples. The system also has software capable of searching the database using the target spectral data as search criteria and returning a match with a data set having standard spectral data that matches the target spectral data. The system optionally has a device that can sense the target spectral data of the target sample and input that target spectral data into the first computer, optionally also non-spectral data and QC capability.

Abstract: The invention provides a composition and method for obtaining both light and dark laser marks of varying shades and intensities on a single plastic article by selectively controlling laser parameters. The invention further provides compositions and methods for obtaining pre-selected one-color and multi-colored designs on plastic articles, by selectively controlling material formulations and laser parameter settings.

Abstract: A method for obtaining both light and dark laser marks on a colored plastic article by using a composition with (i) a thermoplastic resin that foams when heated, (ii) about 0.4% to 0.7% by weight of a mica based laser energy absorbing additive and (iii) a coloring agent with one or more colorants selected from the group of pigments, dyes, and mixtures of pigments and dyes. Using a laser at certain settings results in charring of the resin to produce dark laser marks. At other selected laser settings, the resin foams to produce a light mark on a colored background. By varying the laser energy settings, various degrees of both foaming and charring can be achieved on a single plastic article, having a single resin composition, resulting in a multicolored laser image produced by various shades of light and/or dark marks against the background color.

Abstract: A process for manufacture of articles comprised of polyethylene terephthalate wherein the PET is colored with a composition comprised of a wax dispersant, ethylene copolymer, and a colorant. In a preferred embodiment, the wax dispersant is a maleated polyethylene wax. In an alternative embodiment, the wax dispersant is a low molecular weight polyethylene wax and the composition further includes linear low density polyethylene. A preferred ethylene copolymer is ethylene-(meth)acrylic acid.
