| 摘要 |
<p>The invention concerns a coating, composition comprising a polymeric binder component and an aqueous medium containing, as a colouring component, a dyestuff soluble in the aqueous medium. Such a coating composition can be advantageously employed in a combination of coating compositions embodying the invention which combination is capable of producing a two-coat system on a surface and comprises at least a first coating composition which is water-based, contains a first colouring component and is capable of providing an undercoating, and a second coating composition capable of providing the gloss, which second coating composition is water-based and contains a polymeric binder component in an amount sufficient to impart the gloss to the said surface and a second colouring component (which may be the same as or different from the first colouring component) which is a dyestuff soluble in the water.</p> |
