EXPANDED COLOR SPACE ARCHITECTURAL PAINT AND STAIN TINTING SYSTEM

摘要

White-pigmented and unpigmented base paints and stains are custom-tinted using an automated colorant dispenser having a minimum fluid dispensing quantity less than 0.01 fluid ounce (<0.3 cm3) and an array of colorants including a green-hued colorant having a color strength greater than that of a comparison colorant containing 12 wt. % PG7 pigment, a blue-hued colorant having a color strength greater than that of a comparison colorant containing 7 wt. % PB 15:2 pigment, and a red-hued colorant having a color strength greater than that of a comparison colorant containing 17 wt. % PR209 pigment. The green-hued or blue-hued colorants are dispensed into the base paint or stain whenever a green-hued or blue-hued tint is required. Light pastel tints in small containers and strong colors in large containers may be prepared without requiring the use of additional colorants having the same general hue and lower color strength.
