Improved packaging films, which are shrinkable, high gas barrier films containing an antifog composition for modified atmosphere packaging of foods and the like. The films are useful for producing a modified atmosphere package useful for the preservation and shelf life extension of food and non-food oxygen sensitive items.

Lidding film for modified atmosphere packaging

A write-erase article formed of a substrate coated on one surface with a cured epoxy coating composition, and coated on another surface with an adhesive. The epoxy-coated surface is markable with dry wipe inks without causing permanent discernible distortion of the substrate. The epoxy-coated surface after marking is substantially fully erasable. The article may be adhered via the adhesive to a support.

Water soluble salts of hydrazone compounds react quickly with aniline compounds in the presence of a peroxidase and hydrogen peroxide to provide a color which can be measured spectrophotometrically or visually, either in solution or when incorporated in a device for the measurement of analytes of interest. These water-soluble hydrazone salts are useful in determining hydrogen peroxide or an analyte which reacts to produce hydrogen peroxide in an aqueous liquid, by, in the presence of a substance having peroxidative activity, physically contacting a sample of a liquid with a dye-forming composition comprising a water-soluble salt of a hydrazone compound and a substituted or unsubstituted aniline compound to produce a colored dye; and detecting the dye formed as a result of the presence of hydrogen peroxide or an analyte which reacts to produce hydrogen peroxide.

A dye is covalently bound to a polymeric film, especially a polyhydric polymer, for assays and other purposes. The dye may be one which, when it comes into contact with hydrogen peroxide, changes color to indicate the presence of hydrogen peroxide. This dyed film may be used in qualitative or quantitative assays. This method chemically immobilizes dyes on support matrices with much higher yields of immobilized dye than has heretofore been possible. The covalently immobilized dye may be immobilized on solid matrix particles and combined with a free-flowing dye component to form a two component dye system. By combining a dyed film-former with a film-opener, the amount of dye available for assay is greatly enhanced. This provides a dye system which can be used to detect and measure quantitatively, accurately and precisely high levels of hydrogen peroxide. These high levels of hydrogen peroxide may result from the enzyme-mediated decomposition of various analytes from undiluted whole blood samples.

Method for immobilizing dye on substrates

A color-forming coupler is provided which can be used in test compositions, as well as methods and apparatus for detection of hydrogen peroxide. The color-forming coupler compounds react with a hydrazone or an aminoantypyrine in the presence of peroxidase and hydrogen peroxide to produce a darkly colored compound. In the presence of peroxidase and hydrogen peroxide, the couplers of the present invention react with a hydrazone or an aminoantipyrine to produce a deeply colored dye, which can be used to give a visual indication of the analyte present in the sample. These couplers can be used in diagnostic tests in which the analyte is converted to hydrogen peroxide. The color-forming couplers are N,N-disubstituted anilines of the formula shown in FIG. 1 , wherein R.sup.1 and/or R.sup.2 =H, C.sub.1 -C.sub.9 alkyl, C.sub.1 -C.sub.9 -C.sub.9 alkoxy, NR.sup.3 R.sup.4 (where R.sup.3 and/or R.sup.4 =H, C.sub.1 -C.sub.9 alkyl, aryl, or heteroryl), F, Cl, Br, I, COOR.sup.5 (where R.sup.5 =H, C.sub.1 -C.sub.9 alkyl, aryl, or heteroaryl), CN, CONR.sup.6 R.sup.7 (where R.sup.6 and/or R.sup.7 =H, C.sub.1 -C.sub.9 alkyl, aryl, or heteraryl), aryl, aryloxy, heteroaryl, heteroaryloxy; and R.sup.11, R.sup.12, R.sup.13, and/or R.sup.14 =H, C.sub.1 -C.sub.9 alkyl, C.sub.1 -C.sub.9 alkoxy, or NR.sup.15 R.sup.16 wherein at least one of R.sup.11 and R.sup.14 is NR.sup.15 R.sup.16 wherein only one of R.sup.11 and R.sup.14 is H or C.sub.1 -C.sub.2 alkyl; where R.sup.15 and/or R.sup.16 =H, C.sub.1 -C.sub.9 alkyl, aryl, or heteroaryl, F, Cl, Br, I, COOR.sup.17, where R.sup.17 =H, C.sub.1 -C.sub.9 alkyl, aryl, or heteroaryl, CN, CONR.sup.18 R.sup.19 (where R.sup.18 and/or R.sup.19 =H, C.sub.1 -C.sub.9 alkyl, aryl, or heteroaryl, aryl, aryloxy, heteroaryl, heteroaryloxy; and n=0-10 and m=0-10 and Z and/or y=H, OH, SH, COOR.sup.8 (where R.sup.8 =H, C.sub.1 -C.sub.9 alkyl, aryl, or heteroaryl), CN, NR.sup.9 R.sup.10 (where R.sup.9 and/or R.sup.10 =H, C.sub.1 -C.sub.9 alkyl, aryl, or heteroaryl), NR.sup.20 NHR.sup.21 (where R.sup.20 and/or R.sup.21 =H, C.sub.1 -C.sub.9 alkyl, aryl, or heteroaryl), where at least one of Z or Y is COOR.sup.8, CN NR.sup.9 R.sup.10, or NR.sup.20 NHR.sup.21 or 4-amino antipyrines.

Sizing materials are applied to porous substrates to retain fluids in the substrate for a discrete period of time. After that time period, the fluid is substantially completely released from the porous substrate. Sizing materials include alkyl ketene dimers, fluorocarbon resins, and fatty acid chlorides.
