Abstract: A transfer film for holographic images is a multilayer structure including a core and at least one outer layer having a sufficient thickness for receiving a holographic image impressed into it. The outer layer is thinner than the core layer and is a propylene/ethylene random copolymer having a DSC melting point in excess of 120° C. and less than 143° C. The outer layer further includes an antistatic/release additive therein for permitting multiple releases of a metallized layer initially applied to the outer layer having the holographic image impressed into it, onto a surface of another substrate.

Abstract: The improved rinse tank includes an external shell and an internal shell. For one embodiment, the external shell preferably defines a five sided open-top tank with a top open to the atmosphere. The internal shell is preferably disposed within the external shell and has a configuration that will accommodate at least two semiconductor wafer boats filled with six inch semiconductor wafers. The external shell is preferably sized large enough to completely immerse the wafer boat and wafers in water when the rinse tank is filled. A chamber may be formed between the external shell and the internal shell within the lower portion of the rinse tank. Two or more deionized water inlets may be provided at the bottom of the rinse tank at opposite corners. Three or more compressed air nozzles may also be provided at the lower portion of the rinse tank. Multiple deionized water jet ports are provided at the internal shell.

Abstract: An oriented polymeric alpha-olefin film having: an isotactic polypropylene homopolymer core; a cold seal release skin layer adherent to one side of the core; and a surface treated cold seal receptive layer or such treated layer with a cold seal cohesive composition over the surface treatment of said layer on the other side of the core. The cold seal release skin layer comprises a slip agent and a blend of two polymers, namely, an ethylene-propylene random copolymer containing about 2% to 8% of ethylene in such copolymer and an ethylene-butylene copolymer containing about 0.5% to 6% of ethylene in such copolymer. The cold seal receptive layer is of an ethylene-propylene random copolymer containing about 2 to 8% of ethylene.

Abstract: There is disclosed an oriented, polyolefin film having a white-opaque cold seal receptive skin layer on one side of a core layer and a vacuum deposited metal layer on the other side of the core layer. The cold seal receptive polyolefin layer contains: (a) a slip agent in an amount sufficient to provide not more than about an 0.4 coefficient of friction to the surface of such layer; and (b) from about 10 to 40% by weight of titanium dioxide. The core layer is substantially free of opacifying filler and/or opacifying voids. The other side of the film is metallized to an optical density of at least 1.5 whereby the white pigment in the sealing layer in cooperation with the metallization gives a strong white-opaque appearance to the cold seal receptive layer.

Abstract: A cationic-dyeable copolyester draw-texturing feed yarn of concentric sheath/core bicomponent filaments, with a sheath of cationic-dyeable polyester, and a core of homopolymer, whereby such feed yarn may be draw-textured on commercially-available machines to give cationically-dyeable textured yarns with a combination of good tensile properties, low broken filament counts and good bulk at economically viable cost.

Abstract: The invention relates to a process for improving the slittability and subsequent wind-up of a roll of clear plastic multilayer coextrusion film by the addition to the skin layer of a slitting aid. The slitting aid is an inorganic filler material the presence of which in the skin layer reduces or eliminates telescoping of the rolled coextruded film, facilitates faster line speeds, and allows the reduction of taper tension as the wind-up process progresses.
