Abstract
A coated plastic sheet made of non-woven polypropylene with embossed or plain surface. Since non-woven polypropylene is water impermeable and water repellent, a plastisol or a resin is applied directly for embossing on the entire surface, or partially embossing to form embossed pattern after a special treatment such as spraying with polyvinyl chloride or applying an ink or paste to form a light, plastic sheet of superior quality at low cost.

A water impermeable and water repellent coated plastic sheet made of a base non-woven, polypropylene (PP) sheet, an intermediate layer of a polyvinylchloride (PVC) film and an uppermost layer of polyvinyl chloride plastisol coating, said (PP) non-woven sheet being made of fiber-grade (PP) resin by melting and spray spinning, said (PVC) intermediate layer being composed of 50-100 parts (PVC) resin, 0-50 parts per 100 parts of resin of of VC-VAC copolymer (vinyl chloride-vinyl acetate copolymer), 50-100 parts per 100 parts of resin of plasticizer, 3-9 parts per 100 parts of resin of stabilizer, 0-1 parts per 100 parts of resin of lubricant, and 0-6 parts per 100 parts of resin of dye;
- and the PVC plastisol for the coating is composed of 60-100 parts per 100 parts of resin of PVC resin, 0-40 parts per 100 parts of resin of thermoplastic rubber, 0-100 parts of resin of stabilizer, 0-50 parts per 100 of resin of filler and 5-20 parts per 100 parts of resin of dye.
A water impermeable and water repellent coated plastic sheet made of a base non-woven, polypropylene (PP) sheet, an intermediate layer of a water based or oil-based ink or paste and an uppermost layer of polyvinyl chloride plastisol coating, said (PP) non-woven sheet being made of fiber-grade (PP) resin by melting and spray spinning, said (PVC) plastisol for the coating is composed of 60-100 parts per 100 parts of resin of (PVC) resin, 0-40 parts per 100 parts of resin of thermoplastic rubber, 0-100 parts per 100 parts of resin of plasticizer, 1-5 parts per 100 parts of resin of stabilizer, 0-50 parts per 100 parts of resin of filler and 5-20 parts per 100 parts of resin of dye.
