Aqueous oil-in-water emulsion scratch cover compositions for covering scratches, blemishes and other damage to finished wooden articles such as furniture, wooden trim and wooden floors with characteristcs comparable to volatile organic solvent-based scratch cover compositions are described which are substantially free of added volatile organic solvents and conventional surfactants. These emulsion compositions comprise 2-10 % of an animal, vegetable or mineral oil that is a liquid and substantially nonvolatile at 25 °C, 0.0001-1 % of at least one organic solvent soluble dye that is soluble in the oil and is substantially water insoluble, an effective amount, preferably 0.01-5 %, of a polymeric electrostatic emulsifier such as an acrylates/C10-C30 alkyl acrylate cross polymer that takes the place of conventional surfactants with the balance comprising water, and optionally, nonionic waxes, nonionic nonvolatile silicone fluids, pigments or no more than about 1 % of nonionic surfactants.
Compositions aqueuses constituées d'une émulsion huile dans l'eau, destinées à recouvrir les égratignures et autres défauts d'aspect causés à des produits finis en bois tels que des pièces de mobilier, des garnitures en bois ou des revêtements de sol en bois. Ces compositions, qui ont des caractéristiques comparables aux compositions de raccord à base de solvant organique volatil, sont principalement exemptes de solvant organique volatil additionel ou de tensio-actif classique. Elles renferment de 2 à 10 % d'une huile animale, végétale ou minérale liquide et essentiellement non volatile à 25 C, de 0,0001 à 1 % d'au minimum une teinture à solvant organique qui est soluble dans l'huile mais essentiellement non soluble dans l'eau, une quantité efficace, de préférence comprise entre 0,01 et 5 % d'un émulsifiant électrostatique polymère, tel qu'un polymère de réticulation d'acrylates/d'acrylate alkyle C10-C30, en lieu et place de tensio-actifs classiques, le reste étant consitué d'eau et, facultativement de cires non ioniques, de fluides siliconés non volatils non ioniques, de pigments ou, au maximum, environ 1 % de tensio-actifs non ioniques.
