摘要:
The disclosed dulled stretched molding of at most 30% in gloss value, which is useful as a general-purpose packaging material, printing paper, tracing paper, etc., is produced from a composition comprising 100 parts by weight of a propylene-ethylene lock copolymer and 3 to 40 parts by weight of a cyclopentadiene type petroleum resin having a ring and ball softening point of at least 160.degree. C. through melt extrusion thereof and stretching of the resulting flat extrudate.There also is disclosed a heat-shrinkable foamed molding of at most 0.85 in density and at least 10% in heat shrinkability at 100.degree. C., which is useful as a packaging material, a tying material, a label material, etc. This heat-shrinkable foamed molding is produced from a composition comprising a crystalline propylene-.alpha.-olefin copolymer having a crystal melting point of at most 150.degree. C. and 5 to 40 wt. %, based on the copolymer, of a hydrogenated cyclopentadiene type resin having a ring and ball softening point of at least 160.degree. C. through melt extrusion thereof and stretching of the resulting flat extrudate.

摘要:
Opaque laminated and stretched products having a total light transmittance of 50% or less are obtained by laminating at least one side of a layer obtained from a composition in which a crystalline polypropylene is blended with a cyclopentadiene type petroleum resin having a softening point of 160.degree. C. or higher, as measured by the ring-and-ball method, in an amount of 3 to 30% by weight based on the total weight of both, with a layer obtained from a crystalline propylene copolymer having a crystalline melting point lower than that of said crystalline polypropylene by 10.degree. C. or more, and, then, stretching the resulting laminate at a temperature lower than the crystalline melting point of the crystalline polypropylene and the softening point of the cyclopentadiene type petroleum resin and at a stretching ratio of 2 or higher in at least a uniaxial direction.
摘要:
An opaque and pearlescent, laminated and stretched product comprises a layer (A) and a layer (B) overlaid on and laminated by melt-adhesion to at least one side of the layer (A). The layer (A) forms a uniform layer comprising 97 to 70% by weight of a crystalline polypropylene and 3 to 30% by weight of a cyclopentadiene type petroleum resin having a softening point of 160.degree. C. or higher and stretched in at least one direction. The layer (B) comprising a crystalline polypropylene whose crystalline melting point is higher or lower than that of the crystalline polypropylene forming the layer (A) by less than 10.degree. C.
摘要:
Provided is a heat-sensitive recording material which uses a polyolefin resin as a base for a support but brings about less inferior appearance such as curling and irregularities and which has an excellent resolution and can provide a vivid recorded image in a high density. The heat-sensitive recording material comprises a void-containing stretched film comprising a crystalline polypropylene resin and dicyclopentadiene petroleum resin as essential components and a heat-sensitive recording layer formed on a surface thereof.

摘要:
An information storage apparatus includes a transmission unit that transmits configuration information to an operation terminal connected to the information storage apparatus, the configuration information indicating whether the information storage apparatus is configured to store location information of the operation terminal; a control unit that performs a process requested by a request sent from the operation terminal; and a storage control unit that stores, in a storage unit of the information storage apparatus, the location information of the operation terminal in association with information related to the process requested by the request. When the configuration information indicates that the information storage apparatus is configured to store the location information, the control unit performs the process requested by the request only when the location information is received from the operation terminal together with the request.
