versatic acid styrene ethylene vinyl chloride butadiene vinylidene chloride vinyl versatate vinyl propionate t butyl acrylate acrylonitrile maleates fumarates and the like including plasticized or other derivatives thereof the amount of the ether derivative of rcl used in the water borne coatings of the invention is the amount effective in providing the desired thickening and rheological properties to the coating composition and thus will depend upon both the rheological properties desired and the ether derivative of rcl employed the preferred minimum amount is about 0 01 wt and the most preferred minimum about 0 05 wt of the wet coating composition the preferred maximum amount is 10 wt and the most preferred maximum amount about 5 wt after incorporating the thickener into the base paint the appearance of the paint should be smooth the viscosity of the resulting paint is then measured in the paint industry this viscosity is referred to as stormer viscosity and measured in krebs unit ku in accordance with the present invention rcl ether derivatives can be used in water borne coatings i e lacquers latex paints etc in the latex paint the pigment for example can be magnesium aluminum silicate hydrated aluminum oxide barium sulfate calcium silicate clay silica talc titanium dioxide or zinc oxide the pigment is determined by the desired results and the manufacturer generally the ratio of the volume of pigment to the volume of total non volatile material present in paint is referred to as the pigment volume concentration pvc which is normally expressed in percent latex paints have a pvc upper limit of 85 preferably 75 and more preferably 65 these latex paints have a pvc lower limit of 10 and preferably 20 more particularly when the latex paint is high gloss paint.
