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.

Waterproof recording material having ground patterns and its

The present invention provides a laminated material for cups good for both hot and cold drinks comprising a base material and a resin layer laminated thereon, wherein the melting point of the aforementioned resin layer is not less than 95.degree. C. when measured by DSC, the difference .DELTA..theta. between the advancing contact angle (.theta.a) and the receding contact angle (.theta.r) for water is not more than 20.degree., and the resin layer has a heat sealability. According to the present invention, a laminated material for cups good for both hot and cold drinks can be provided, these cups being also excellent in bubble-arresting property and sliding property as well as vending property.
