US Patent:

58691766, Feb 9, 1999

Filed:

Nov 6, 1997

Appl. No.:

8/965236

Inventors:

John J. Dorchester - Mansfield TX
Bobby D. Smith - Arlington TX
Ronald M. Harris - Alpharetta GA

Assignee:

M. A. HannaColor, a division of M. A. Hanna Company - Suwanee GA

International Classification:

B32B 516

US Classification:

428327

Abstract:

A new and useful a plastic article, particularly plastic siding, with an accent color pattern incorporated therein, a specially formed accent color pellet which is useful in manufacturing such an article, and a process for producing the article using the pellets are provided. The process contemplates extruding a plastic product from a base material formed of powder-sized particles and specially formed accent color pellets. The accent color pellets are alloyed masses of resins and pigment which are larger than the powder particles of the base material, and have a higher vicat softening point temperature than the base material. The alloyed pellets are designed to melt controllably and to mix controllably with the base material. During the extrusion process, the accent color pellets begin to soften and disperse later than the base material, and cause controllable dispersion of the accent color into the base material, thereby producing accent color streaks in the resulting product having controllable characteristics. The process is particularly suited for producing a simulated wood-grain or streaking effect in plastic siding, and as described can produce hard streaking, soft streaking, and a mottled or variegated streaking in which more than one accent color is used simultaneously.
