Embodiment 1
[0051] The viscosity of Example 1 is 2.5 times higher than Comparative Example A, which facilitates good shelf life and ease of pumping.
[0052] The molding test was carried out by blow molding a mixture of 99.95 weight percent PET resin and 0.5 weight percent of the color masterbatch of Example 1 to obtain a bottle. The bottle has good clarity and acceptable color. A single stage Aoki PET stretch blow molding machine was used for this purpose. The melting temperature in the blow molding machine is around 274°C.

Abstract
A liquid color concentrate is disclosed, having a polyalkylene polyol carrier; colorant; and optionally other functional additives. The colorant can be one or more pigments, one or more dyes, or combination thereof. The liquid color concentrate is compatible with polyalkylene terephthalate resins, especially to make colored polyester beverage bottles and other polyester articles.
Description
[0001] claim priority [0002] This application claims priority to U.S. Provisional Patent Application No. 60 / 974616, filed September 24, 2007, Attorney Docket No. 12007018, which is incorporated herein by reference. technical field [0003] The present invention relates to the use of liquid polymers as a carrier for colorants used as masterbatches for the production of colored polyester articles. Background technique [0004] Plastics have replaced other materials in a wide variety of industries. In the packaging industry, plastics have replaced glass to minimize breakage, reduce weight, and reduce energy consumption in manufacturing and shipping. In other industries, plastics have replaced metals to minimize corrosion, reduce weight, and provide integrally colored products. [0005] Attracting consumers to purchase personal-sized or family-sized containers includes branding and product packaging. Among these elements valuable commodity packaging is the color of the cont...
