  • Patent number: 4472462
    Abstract: A method of applying fluid paint utilizes a marking device having a fluid paint-filled reservoir, a tip comprising a spring-loaded ball and its spring, and pressure means, such as collapsible walls or a pressure device, to apply pressure to the fluid. The paint, applied to a fabric as a decoration, is an oil-in-water emulsion in which oil mixture droplets (globules) are evenly dispersed in the water phase. The oil droplets are composed of an oil mixture preferably based on an oil-modified polyurethane or oil-modified alkyd or other oil-modified resin and drying agents. The oil-in-water emulsion contains a surfactant, a gellant, and an anti-foam agent. The pigment dispersion may be in the oil droplets or in the water phase.
