    Abstract: A protective layer which prevents marine fouling when attached to a boat hull or other structure intended to be submerged underwater. The protective layer achieves its anti-fouling characteristic by incorporating anti-fouling compounds uniformly dispersed throughout either a plastic film or an adhesive used to bond the film to a surface to be protected which slowly leach into the surrounding marine environment. The film is removably adhered to a boat hull or other structure by a thermally sensitive thermoplastic adhesive. The film may be removed by simply reheating until the adhesive softens to thereby allow the film and any undesired marine organisms attached thereon to be peeled away from the boat hull.

  • Patent number: 6565985
    Abstract: A polyamide resin-based heat-shrinkable multilayer film is caused to satisfy various properties required of a packaging material, especially a food packaging material, at high levels, and particularly exhibit a highest level of heat-shrinkability. The multilayer film comprises at least three layers including an outer surface layer (a) which comprises a polyester resin or a polyolefin resin; an intermediate layer (b) which comprises a mixture of 85-60 wt. % of an aliphatic polyamide resin, and 15-40 wt. % of an aromatic copolyamide resin which is a copolymer of aliphatic diamine/isophthalic acid and aliphatic diamine/terephthalic acid, and an inner surface layer (c) which essentially comprises a copolymer of ethylene and &agr;-olefin having a density below 0.915. The heat-shrinkable multilayer film has been biaxially stretched and then heat-treated to have hot-water shrinkabilities at 80° C.

  • Patent number: 6554941
    Abstract: Method for laminating a pre-press proof (200), whereby an imaged receiver sheet (140) with a representative image (290) having been written with an incorrect orientation can be salvaged, which comprises the steps of laminating a pre-laminate sheet (240) to a sheet of receiver stock and removing the first support layer (150). Laminating an imaged receiver sheet (140) consisting of a representative image (290) that has been formed with an incorrect orientation on a second thermoplastic layer (304) and a second support layer (170) to an imageless receiver sheet (160) consisting of a third thermoplastic layer (306) and a third support layer (180). Thereby encapsulating the representative image (290) between the second thermoplastic layer (304) and third thermoplastic layer (306) and removing the second support layer (170) forming a laminated imaged receiver sheet (190).

  • Patent number: 6544371
    Abstract: A method of securing semiconductor chips comprises the steps of: sticking semiconductor chips at their backs to a transfer tape having an adhesive superimposed thereon at spaced intervals; peeling the semiconductor chips from the transfer tape such that the adhesive is transferred onto the backs of the semiconductor chips; and securing the semiconductor chips by way of the adhesive onto a substrate. The method also includes variations such as sticking the transfer tape to a substrate at predetermined sites for securing semiconductor chips and then peeling the base material of the transfer tape to transfer the adhesive to the predetermined sites on the substrate, followed by securing the semiconductor chips thereto.

  • Patent number: 6531016
    Abstract: Described is a process for the region-wise transfer of a decorative layer of a transfer foil, which includes an activatable adhesive layer from a carrier film onto a substrate, wherein the adhesive layer of the transfer foil is partially activated before the actual stamping operation, more specifically in such a way that the adhesive layer experiences activation only in the surface regions in which the decorative layer is to be transferred onto the substrate. A transfer foil which is particularly suitable for that process has an absorption layer in the surface regions of the decorative layer, which are to be transferred onto the substrate, which absorption layer absorbs the radiation energy causing activation of the adhesive layer and activates the adhesive layer under the action of the absorbed radiation energy.
