An ink-jet printing process including the steps (a) and (b) in any order or simultaneously: The process avoids the need for expensive special papers previously used for ink jet printing.

Ink-jet printing process

A composition comprising a C -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.

Biocidal composition and its use

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.

Biocide composition and use

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.

Composition and use

The present invention provides a lubricant composition comprising a lubricating oil and, as multifunctional additive, at least one compound having the formula I: ##STR1## or amine salts thereof; wherein R.sub.1 and R.sub.2, independently, are hydrogen or methyl; n and m, independently, are 0 or 1; and X is SR.sub.3 or NR.sub.4 R.sub.5 wherein R.sub.3 is C.sub.12 -C.sub.20 linear or branched alkyl R.sub.4 and R.sub.5 are independently, C.sub.8 -C.sub.20 linear or branched alkyl provided that those compounds of formula I are excluded in which m and n are each 0, X is S-C.sub.8 -C.sub.20 linear or branched alkyl and R.sub.1 and R.sub.2 are as defined.

Lubricant compositions

The present invention provides a lubricant composition comprising a lubricating oil and, as a multifunctional additive, at least one compound of formula (I) ##STR1## in which R.sup.1 and R.sup.2 are, independently, hydrogen or C.sub.1 -C.sub.20 alkyl and R.sup.3 is hydrogen, C.sub.1 -C.sub.20 alkyl or a group of the formula ##STR2## wherein R.sup.4 is H or C.sub.1 -C.sub.20 alkyl. Most of the compounds of formula I are new.

Lubricant composition containing multifunctional lubricant additives

New composition comprises a functional fluid in contact with ferrous metal and a corrosion inhibiting amount of at least one compound of formula (I) ##STR1## or a derivative thereof in which R.sup.1, R.sup.2 and R.sup.3 are, independently, hydrogen, a C.sub.1 -C.sub.15 straight or branched chain alkyl residue, a C.sub.5 -C.sub.12 cycloalkyl residue, a C.sub.6 -C.sub.15 aryl residue or C.sub.7 -C.sub.12 alkaryl residue, and R.sup.4 and R.sup.5 are, independently, hydrogen, 2-hydroxyethyl or 2-hydroxypropyl with the provisos that
