There is provided a stable, concentrated fabric rinse composition comprising 0.1 to 20, preferably 1 to 10% by weight of a UV absorber selected from a hydroxyaryl-1,3,5-triazine, a sulphonated-1,3,5-triazine, an o-hydroxyphenylbenzotriazole or a 2-aryl-2H-benzotriazole, based on the total weight of the composition, and a fabric care ingredient, preferably a fabric softener, a stain release or stain repellant ingredient or a water-proofing agent, the remainder being substantially water. The fabric rinse composition is preferably a fabric softener composition comprising 5 to 25, preferably 10 to 20% by weight of a cationic fabric softening agent and 0.1 to 20, preferably 1 to 10% by weight of a UV absorber selected from a hydroxyaryl-1,3,5-triazine, a sulphonated-1,3,5-triazine, an o-hydroxyphenylbenzotriazole or a 2-aryl-2H-benzotriazole, each based on the total weight of the composition, the remainder being substantially water. The present invention also provides method for the treatment of a textile article, comprising applying, to the previously washed article, the said fabric rinse composition, preferably the rinse cycle fabric softener composition, whereby the SPF value of articles so treated can be significantly increased.

The invention relates to o-hydroxyphenyl-s-triazines of formula ##STR1## wherein at least one of Y and Z are C.sub.1 -C.sub.18 alkoxy The compounds are suitable for use as UV stabilisers for the photochemical and thermal stabilisation of polyester fibre materials and as stabilisers for organic ploymers.

Hydroxyphenyl-s-triazines

Process for flame-proofing organic polymeric materials

o-Hydroxyphenyl-s-triazines are described which contain at least two alkoxyphenyl substituents. They have the formula (1). The compounds according to the invention are suitable as stabilizers for textile fiber materials, in particular polyester fiber materials, and for organic polymers. Furthermore, they are suitable for use as sunscreens in cosmetic preparations.

Water-emulsifiable or -dispersible physical forms of sterically hindered mines, UV absorbers and antioxidants and their use for thermal and photochemical stabilization of materials of plastics, textile coatings, imitation leather and leather are described. The physical forms comprise

Stabilizing leather against thermal and photochemical decomposition

A process is described for the photochemical and thermal stabilisation of undyed and dyed polyester fibre materials, which comprises treating said materials with a compound of formula ##STR1## wherein R.sub.1 and R.sub.2 are each independently of the other C.sub.1 -C.sub.12 alkyl. Dyeings and prints of superior lightfastness and sublimation fastness on polyester and cellulose acetate are obtained by this process.

Process for the photochemical and thermal stabilization of undyed and

Sterically hindered phenols of formula (1) are disclosed. These antioxidants are suitable for enhancing the thermal and photochemical stability of undyed and dyed polyamide fibre materials. They are distinguished by superior exhaustion which is almost independent of the pH.

Sterically hindered phenols

Compounds of the formula I, II, III and IIIa ##STR1## in which Ar.sup.1 is an unsubstituted or substituted aromatic radical and at least one of the radicals R.sup.1 and R.sup.2 is an alkenyl, cycloalkenyl or arylmethyl group, are effective photoinitiators for photopolymerization of unsaturated compounds. They are particularly suitable for photocuring of pigmented systems.

A-aminoacetophenones as photoinitiators

.alpha.-aminoacetophenones as photoinitiators

Light-stabilized polymer microparticles, which contain at least one light stabilizer, and processes for the preparation of these microparticles by polymerization of suitable monomers, at least a part of the polymerization being carried out in the presence of at least one light stabilizer, are described. The polymer microparticles can be used in coating compositions which comprise a disperse phase containing these particles and a liquid continuous phase. Coatings and finishes based on the compositions according to the invention are distinguished by improved weathering resistance, in particular by a high light stability.

Light-stabilized polymer microparticles

Water-soluble triazine derivatives of the formula (1) are described. The compounds are representatives from the class of sterically hindered mines (HALS stabilizers). They are suitable for increasing the thermal and photochemical stability of dyed and undyed polygamies fibre materials.

Water-soluble triazine derivatives

A process is disclosed for treating polyamide fiber containing materials which process comprises applying a benzofuran-2-one compound to the material in order to enhance its moulding stability. In addition, compositions containing a fluorescent whitening agent and a benzofuran-2-one, and optionally one or more dyes, are disclosed.
