A polyacetal resin composition containing 100 parts by weight of a polyacetal resin, 0.01 to 5 parts by weight of a colorant selected from inorganic and organic pigments, 0.01 to 3 parts by weight of a polyamide resin having a melting point or softening point of 180.degree. C. or less, or a polyetheresteramide resin, 0.01 to 1 part by weight of an aromatic dihydrazide compound or an aliphatic dihydrazide compound having a solubility of less than 1 g relative to 100 g of water at 20.degree. C., and 0.01 to 1 part by weight of a sterically hindered phenolic compound, or a combination of a hindered amine-based light stabilizer and an ultraviolet absorber, exhibits an excellent thermal stability and is capable of suppressing formaldehyde generation and mechanical strength deterioration.

Polyacetal resin composition, resin molded article, and method and agent for improving polyacetal resin raw material composition

The present invention relates to combinations of imazalil, or a salt thereof, and silver compounds which provide an improved biocidal effect. More particularly, the present invention relates to compositions comprising a combination of imazalil, or a salt thereof, together with one or more silver salts selected from silver acetate, silver alginate, silver azide, silver citrate, silver lactate, silver nitrate, silver sulfate, silver chloride, silver thiocyanate, silver-sodium-hydrogen-zirconium phosphate, silver sulfadiazine, silver cyclohexanediacetic acid and disilver 2,5-dichloro-3,6-dihydroxy-2,5-cyclohexadiene-1,4-dione; in respective proportions to provide a synergistic biocidal effect. Other suitable silver components (II) are products that set silver free using technologies to make it gradually biologically available such as by ion exchange mechanisms such like using zirconium phosphate based ceramics as a reservoir, or silver provided in glass ceramics as reservoir or carrier, or silver provided with zeolites, silica gel or titanium dioxide as a reservoir or an inorganic derivative containing silver, incorporated into a plastic composition for the preparation of moulded, lacquered or painted products, such as an amino resin (e.g. urea-formaldehyde resin, melamine formaldehyde resin . . . ) or a thermoplastic (e.g. a polyester, polyethylene, polyacrylate, pvc . . . ), or provided as nano-silver particles typically with a particle size of 20-1000 nm. Compositions comprising these combinations are useful for the protection of any living or non-living material, such as crops, plants, fruits, seeds, objects made of wood, thatch or the like, biodegradable material and textiles against deterioration due to the action of microorganisms such as bacteria, fungi, yeasts, algae, and the like.

Combinations of imazalil and silver compounds

Copper electroplating liquid which does not use formaldehyde, which is harmful to the environment, and which exhibits excellent via filling ability is offered. The copper electroplating liquid of this invention includes the compound that has the structure of --X--S--Y-- where X and Y are each an atom selected from the group of hydrogen atoms, carbon atoms, sulfur atoms, nitrogen atoms and oxygen atoms, and X and Y can be the same only when they are carbon atoms, and a specific urea derivative. When the copper electroplating liquid is used, deterioration of the appearance will not occur and a good filled via can be formed.
