Abstract: Solid anti-fogging agents such as 5-nitroindazole which are otherwise poorly soluble in water are converted to readily water soluble compositions that are solids at room temperature when they are first dissolved in water soluble polymers or other organic compounds that have a melting point above room temperature and do not chemically react with the anti-fogging agent. The anti-foggants are preferably dissolved in the polymer or organic compound at or near the compounds' melting point below 175.degree.C.

These graft copolymers are useful in preparing water-based flexographic, i.e. packaging laminating inks, comprised of a pigment; the graft copolymer; a binder resin; an alkanol; an alkali, ammonia or an amine; and water.

Abstract: A method and system for transferring a flowable material from a container to a receiver through a flexible tubing which communicates with an opening defined in the container and which extends outwardly from the container. The method involves establishing within the container, after discharge of the material therefrom, a pressure less than the ambient pressure so as to draw the tubing into the container through the opening as a result of the pressure differential created between that within the container and the ambient pressure.

Abstract: The present invention features a negative-type, silver halide photographic emulsion containing hydrazides that has reduced scratch sensitivity (i.e., the emulsion will have a reduced tendency to develop black scratches on non-exposed areas). The emulsion will resist developing black scratches due to the introduction to the emulsion of hydroquinone and ascorbate. The stability of the emulsion is further enhanced by the addition of sodium formaldehyde bisulfite.

Abstract: Printing fluid for printing cellulosic materials comprising (a) water; (b) a cationic polyaminoamide/epichlorohydrin resin; (c) a water soluble cationic dye; and (d) 0 up to about 3 wt. %, based on the weight of the printing fluid, of a bleachable pigment. The fluid preferably also contains up to about 50 wt. %, based on the weight of the fluid, of urea to enhance color strength. The printing fluid has excellent bleed resistance to common household products but is nevertheless bleachable so that printed materials such as paper toweling may be repulped and recycled.

Abstract: An aqueous composition useful for the protection of actinic light-exposed presensitized lithographic printing plates. The composition comprises an effective amount of (a) an ammonium, sodium, potassium or lithium salt of a strong organic acid, and (b) an ammonium, sodium, potassium or lithium salt of an anionic surfactant which contains functionalities of the salt of a strong organic acid and the salt of a weak organic acid, and (c) an ammonium, sodium, potassium or lithium salt of a weak organic acid. The composition is applied to the surface of the plates after they have been developed, but before they have been baked, thereby preventing surface contamination that would otherwise occur from the heat treatment.

Abstract: Printing inks comprising a pigment and an aqueous or non-aqueous solvent (or a mixture of such solvents) have reduced abrasiveness towards printing surfaces (e.g. gravure printing cylinders) by incorporation in the ink of an alkoxylated dibasic phosphate ester and at least one alkali metal salt of a dialkylsulfosuccinic ester.

Abstract: A printing ink composition having a high degree of rub-off resistance comprising (a) a dispersion of a pigment in a vehicle containing a C.sub.7 -C.sub.40 oil and (b) a polymer latex emulsified in said dispersion. When employed for printing at high speeds, an anti-misting compound such as tridecyl acid phosphate, phosphoric acid, glycerol, or propylene carbonate is preferentially added to the ink composition. Where cost is not of paramount concern, a polytetrafluoroethylene wax is preferentially added to the ink composition.

The poly (alkylene oxide) substituted acetoacetanilides are prepared by reacting a poly (alkylene oxide) monoamine, diamine or triamine with isatoic anhydride followed by acetoacetylation of the resultant aminobenzamide. The substituted acetoacetanilides are useful for preparing improved diarylide pigment compositions which in turn are useful for preparing storage stable printing inks (especially of the publication gravure type).

The pigment compositions are prepared by reacting a primary amine-terminated alkylene oxide polymer and an acetoacetanilide to form an azomethine coupler and subsequently preparing the monoazo pigment composition by reacting the desired diazo component and coupling component in the presence of the azomethine coupler so as to form an azomethine composition of matter and the desired pigment.
