Abstract

Abstract The present invention provides a waterproof recording material having ground patterns characterized in that the ground patterns are imparted to the surface of a film of a resin composition comprising a thermoplastic synthetic resin and a filler. According to this invention, it is possible to provide a fine-looking recording material which, besides excellent waterproofness and recording property, may have various stages of surface properties and visual effects imparted by means of the ground patterns. The waterproof recording material having ground patterns of the present invention is suitable as a material of valuable securities and the like, facilitating true/false discrimination and preventing illegal use or abuse thereof by altering, falsification et cetera.

Claim 10
Independent Claim 68 words
A method of manufacturing a waterproof recording material having ground patterns, wherein a resin composition prepared by mixing a filler to a thermoplastic synthetic resin is extruded in film form in between a substrate and the pattern side of a sheet having patterns and after pressing and cooling the sheet is separated for its patterns to be transferred onto the surface of a film of the resin composition.
Claim 11
Independent Claim 68 words
A method of manufacturing a waterproof recording material having ground patterns, wherein a resin composition prepared by mixing a filler to a thermoplastic synthetic resin is extruded in film form in between a substrate and the pattern side of a sheet having patterns and after pressing and cooling the sheet is separated for its patterns to be transferred onto the surface of a film of the resin composition.
Claim 12
Independent Claim 74 words
A method of manufacturing a waterproof recording material having ground patterns, wherein a resin composition prepared by mixing a filler to a thermoplastic synthetic resin is extruded in film form on a substrate and it is then pressed and cooled by the use of a cooling roll having patterns on the resin composition side to thereby transfer the patterns of the cooling roll onto the surface of a film layer of the resin composition.
Claim 13
Independent Claim 74 words
A method of manufacturing a waterproof recording material having ground patterns, wherein a resin composition prepared by mixing a filler to a thermoplastic synthetic resin is extruded in film form on a substrate and it is then pressed and cooled by the use of a cooling roll having patterns on the resin composition side to thereby transfer the patterns of the cooling roll onto the surface of a film layer of the resin composition.
