Abstract
A monolithic particle-containing layer in multi-layered sheeting (for example, sheeting of the type comprising resilient vinyl flooring) is produced by applying a composition comprising a liquid material having dispersed therein decorative particles (for example, a vinyl plastisol containing dispersed vinyl dryblend particles) to a surface of a layer of the multi-layered sheeting, the application of the composition being preferably by the reverse roll coating method.
Claims9
In a continuous process for making a flooring material comprising multi-layered sheeting of indefinite length and having a predetermined width and including a monolithic layer which is substantially co-extensive with the width of said sheeting, wherein said monolithic layer contains decorative particles having a size of at least about 100 microns, the improvement comprising:
- forming said monolithic layer by continuously applying by a reverse roll coater to the surface of a layer of said multi-layered sheeting in a zone extending across substantially the entire width of the surface a plastisol consisting essentially of a liquid plasticizer and fine particles of a vinyl resin suspended therein and having dispersed therein said decorative particles, said plastisol being applied as the sheeting is continuously moved transversely of said zone and under conditions such that the thickness of the monolithic layer formed from said plastisol is substantially uniform and the decorative particles are substantially uniform dispersed therein;
- and permanently adhering said monolithic layer of decorative particles to the surface of said layer, thereby providing a flooring material comprising a monolithic layer having a substantially uniform thickness and decorative particles substantially uniformly dispersed therein.
