Abstract: A composition for inhibiting the growth of microorganisms on non-cellulosic fibers having a moisture regain of ?5%, comprising; i) 1 to 50 wt % of at least a self-crosslinkable resin; ii) 0.25 to 20 wt % of at least a catalyst; iii) 0.1 to 4 wt % of at least an antimicrobial active agent, reactive with the resin; iv) 98.65 to 26 wt % of water; wherein i)+ii)+iii)+iv)=100%.

Abstract: An air-filter for a circulating and/or recirculating air system using a filter medium containing a microbiologically effective amount of a polymeric biguanide or salt thereof. Also claimed is a method for reducing odors and/or air-borne micro-organisms in a circulating or recirculating air system using the air-filter, and a method for protecting an air-filter medium against microbial degradation by incorporating in, or on, the medium a microbiologically effective amount of a polymeric biguanide or salt thereof.

Abstract: An ink-jet printing process including the steps (a) and (b) in any order or simultaneously: (a) applying an ink to a substrate by means of an ink-jet printer in a localized manner to form an image on the substrate; and (b) applying to the substrate a composition including a liquid medium and a poly(C3-18-hydrocarbyl monoguanidine) or a salt thereof by means of an ink-jet printer. also a substrate printed by means of this process, compositions including poly(C3-18-hydrocarbyl monoguanidines), sets of liquids for use in ink-jet printing and ink-jet printer cartridges. The process avoids the need for expensive special papers previously used for ink jet printing.

Abstract: A coating composition comprising pigment, medium and binder comprising a poly(C3-18-hydrocarbyl mono guanidine) and characterised in that the weight ratio of pigment to binder in the composition is at least 2:1. Also a recording material comprising this composition, a process for forming the recording material, and an ink-jet printing process utilizing the recording material.

Abstract: An ink-jet printing process comprising the steps (a) and (b) in any order or simultaneously:

Abstract: A composition comprising a C3-5-alkyl-1,2-benzisothiazolin-3-one and the metal complex of a cyclic thiohydroxamic acid such as the 2:1 zinc salt of either 3-hydroxy-4-methylthiazol-2(3H)-thione or 1-hydroxypyridine-2-thione.

Abstract: A method for the preservation of a plastics material against the growth of deteriogens which comprises treating the plastics material with a composition comprising a) an isothiazolin-3-one such as N-n-octyl- or 4,5-dichloro-N-n-octyl-isothiazolin-3-one and b) the metal complex of a thiohydroxamic acid such as 2:1 zinc complex of 3-hydroxy-4-methylthiazol-2(3H)-thione or the 2:1 zinc complex of 1-hydroxypyridine-2-thione.

Abstract: A composition comprising (a) a metal complex of a cyclic thiohydroxamic acid such as the 2:1 zinc complex of 3-hydroxy-4-methylthiazol-2(3H)-thione and (b) a salt of the metal such as zinc chloride, acetate or oxide. The presence of component (b) gives enhanced microbiological activity.

Abstract: Stable aqueous dispersions of 1,2-benzisothiazolin-3-one containing Xanthan gum which is substantially free from organic solvents.

Abstract: A composition comprising a cellulosic non-woven material containing a mixture of polymeric biguanides such as poly(hexamethylene biguanide) together with an anionic polymer such as a polyacrylic acid super-absorbent and the use of such composition in disposable articles such as nappies.

Abstract: A compact pellet tester for testing the durability of animal feed pellets. The tester comprises a perforated hopper into which a high velocity stream of air is directed upward to agitate the pellets to measure the amount of material or fines which break off during testing.

Abstract: Antimicrobial treatment of textile material with an oligomeric or polymeric biguanide and a strong organic acid having a pK value below 4.5. Acid protects treated material against yellowing the presence of chlorine bleaches and loss of antimicrobial activity on laundering. The preferred biguanide is poly(hexamethylene biguanide) hydrochloride.
