摘要:
The two stage production of clear, low-haze, injection stretch blow molded polypropylene container articles is disclosed. In the first processing stage, a preform article is manufactured on an injection molding machine. In a second and subsequent step, which may occur remotely from apparatus used in the first step, the preform article is heated and stretch blown into a container. The process may employ the selection of processing parameters to produce preform articles that facilitate stretch blow molding at relatively high rates of speed, while still maintaining an appropriate polypropylene polymer morphology that results in clear, low haze containers.

Novel, quick, and reliable detection methods for determining the authenticity of optical and/or audio disc articles (such as compact discs, digital video discs, CD-ROM discs, and the like) are provided. Such a method basically entails the incorporation of an identifier or marking means within the edges of target optical discs or within any other portion of a target disc such that exposure to non-visible light sources will provide the desired identification upon irradiation or detection of the marking means therein. Such an identifier or marking agent thus may be utilized in conjunction with a transparent holding case whereby the needed light source may be exposed through the transparent walls thereof to permit detection of counterfeit or authentic discs without requiring opening of the case itself. Such a method may also be utilized for discs that are removed from or have not been placed and sealed within such a case as well. Specific methods of utilizing particular transparent cases are thus also encompassed within this invention. Specific methods of utilizing particular transparent cases are thus also encompassed within this invention as are novel storage unit configurations to maximize the benefits of the transparent properties thereof.
摘要:
Novel optical disc storage units comprising transparent polypropylene are provided. Such storage units exhibit sufficient impact resistance to protect the target disc and sufficient clarity that any informational literature may be placed entirely within the storage unit and easily viewed and read through the walls thereof without impediment. Furthermore, the target storage unit must also include a spine section of sufficient width to permit a section of the informational literature to be placed internally thereon and viewed and easily read (such as, for example, the title and accompanying language describing the target disc placed therein) substantially without impediment as well. Additionally, provided therein are novel insert trays that simultaneously permit proper placement of such internally placed informational literature against the internal portion of the aforementioned walls, and particularly the spine portion, as well as provide antitheft properties. Such insert trays are designed to encompass any discs placed therein to the extent that such discs cannot exit such trays when the container is in closed position without breaking the disc itself. Specific novel storage units, in addition to these necessarily transparent walls and spine portions, are also possible to maximize the benefits of the transparent properties thereof.

Novel, quick, and reliable detection methods for determining the presence and/or authenticity of optical and/or audio disc articles (such as compact discs, digital video discs, CD-ROM discs, and the like) when present within a holding container are provided. Specific methods of utilizing particular transparent cases are encompassed within this invention. Specific methods of utilizing particular transparent cases are thus also encompassed within this invention as are navel storage unit configurations to maximize the benefits of the transparent properties thereof.
摘要:
Black polyurethane foams that exhibit higher strength black colorations without the need for concomitant increases in black colorants therein are provided. Such a resultant jetter black foam article is possible through the unexpectedly effective introduction of small amounts of certain toner compounds or combinations that exhibit specific measurable appearance characteristics. Such toners exhibit at least one absorption peak within a specific range of wavelengths (e.g., from about 560 to 610 nm) and specific ranges of half-height bandwidths (from 40 to 130 nm). Furthermore, such a compound or combination of compounds, is preferably liquid in nature (at room temperature) or in dispersion form and may thus be easily incorporated within target polyurethane precursor compositions for admixture with either black pigments (or dispersions thereof), black polymeric (liquid) colorants, or both. Methods of high strength black polyurethane foam production as well as separate pigmented and liquid polymeric colored foams of such type including the necessary toner compounds and/or combinations, as noted above, are also encompassed within this invention.
摘要:
A novel colorant compound is provided which is the addition product of an organic chromophore having at least one reactive hydroxyl or amine substituent, a mono or polyisocyanate, and/or an alcohol. In addition, colorants that provide the same toning characteristics for black offset ink compositions as this novel colorant are provided. Such a compound provides solubility in oil-based ink compositions, complete water resistance and excellent oil based ink compositions. Furthermore, such colorants provide an easy and efficient way to tone shades of oil based inks. In addition, such colorants provide a way to tone carbon black based lithographic inks that gives these inks a appearance of jet black on various types of printing substrates. A method for producing such a colorant is also provided, as well as offset ink compositions comprising such a colorant (including other colorants that provide the same toner performance within black pigment formulations).

摘要:
Novel addition products of isocyanates with oxyalkylene-substituted aminophenol compounds as intermediates for the production of urethane-substituted xanthene colorants, particularly triphenylmethane derivatives such as rhodamines, are provided. The xanthene colorants exhibit improved wax and/or oil solubility and high purity. The urethane-substituted xanthene colorant features very good wax and/or oil solubility, and is believed to be relatively nontoxic. A method for producing this novel colorant is also provided.

A novel, easy, and efficient manner of toning shades of toluene-based gravure inks is provided, particularly through the incorporation of certain polymeric colorannts therein said gravure ink formulations. In addition, such toner additives provide a toning capabilities of carbon black-based gravure inks that provides jetter black appearances with lower degrees of redness and bronzing on various types of printing substrates than other toner formulations of standards alkali blue types of toning additives. Such printed substrates and methods of printing utilizing such novel gravure toner additives are also encompassed within this invention.
