ABSTRACT:
A rugged shaped sheet capable of exhibiting improved non-slip properties and aesthetic properties and a process for manufacturing the same. The rugged shaped sheet includes a base sheet member and a rugged pattern of a predetermined shape adhered to the base sheet member. The rugged pattern is formed of a plurality of pattern elements different in size, configuration and/or properties into a multi-layer structure. The rugged shaped sheet is manufactured by pouring an elastomer liquid material into each of perforated plates, semicuring the elastomer and laminating the perforated plates on each other, resulting in forming the rugged pattern of a predetermined shape on the base sheet member.
