Abstract: Piling due to ink, paper fibers and/or clay fillers occurs frequently during an offset printing process, resulting in the deterioration in print quality and lost manual time due to the necessity to clean the equipment. It has been experimentally found that small quantities of certain high molecular weight polyethylene oxide polymers can alleviate this serious problem. However, the overall effectiveness will depend on the concentration of the total make-up of component in the fountain solution.

Abstract: This invention relates to new and novel compositions and processes, whereby hindered amine light stabilizers (HALS) having either one or more amido or imido groups and/or a phenolic or anilino group are reacted with an aldehyde to give hydroxy, alkylated groups. These hydroxyalkylated groups can be further reacted with lower alkyl alcohol's to give the more stable alkoxylated derivatives. The above compositions can then be used as reactive HALS for the following polymeric systems, e.g., aminoplasts epoxies, polyesters, polyamides, and urethanes and others to confer photo stabilization.

Abstract: Linear, polymeric biguanides or salts thereof wherein the polymeric chain is terminated at the cyanoguanidine end group by a C.sub.2 -C.sub.90 primary or secondary amine which is optionally substituted with a functionality such as fluoride, chloride, bromide, iodide, nitro, hydroxyl, ether, sulfide, disulfide, sulfoxide or sulfone. The polymeric biguanides have a high level of biocidal activity accompanied by a low level of toxicity to host organisms and are therefore useful in bactericidal, algicidal and fungicidal compositions, especially in ophthalmic compositions.

Abstract: Novel aminosaccharide biguanides are prepared by either reacting a aminosaccharide with a mono- or multi-functional cyanoguanidine or by reacting a monocyano-guanidine of an aminosaccharide with a mono- or multi-functional primary and/or secondary amine.

Abstract: A one-step process for sterilizing a contact lens using an aqueous solution of a sterilant which may be a peroxygen disinfectant, an inorganic hypochlorite compound or a hypochlorite precursor compound. The process involves the step of contacting the lens with a solution containing a sterilant (e.g. hydrogen peroxide, sodium hypochlorite, etc.) and activated carbon for a period of time to effect sterilization of the lens and to decompose substantially all of any sterilant remaining after sterilization of the lens to ophthalmologically innocuous by-products. The activated carbon has a surface area in excess of about 500 m.sup.2 /g and a pore volume of at least about 0.75 ml/g.
