Stabilized organic material

o-Hydroxyphenyl-s-triazines of the formula I

A composition for controlling harmful insects and representatives of the order Acarina, containing as biologically active components a) a substance that modifies the behavior of the pests and b) at least one pesticidally active compound, wherein the biologically active components are contained in a flowable or viscous non-hardening matrix that is resistant to water and weather, is protected against light and is suitable for distribution in the form of droplets or droplet-like units or spots that adhere to a substrate, by means of which matrix the behavior-modifying substance is protected against UV radiation and from which it is slowly released in a biologically effective amount over a prolonged period, and wherein the pesticidally active compound can be taken up in a pesticidally effective amount from the surface of the droplets or droplet-like units or spots by the pests to be controlled; as well as a method of controlling the said pests, especially plant-destructive insects.

o-Hydroxyphenyl-s-triazines of the formula I ##STR1## in which n is 1 to 4 and R.sub.1 to R.sub.7 are as defined in claim 1, can be used, in combination with sterically hindered amines of the polyalkylpiperidine type, for stabilizing organic polymers. Some of these compounds are novel and can also be used without polyalkylpiperidine.

Compounds which comprise at least one group of the formula I or II ##STR1## and at least one polyalkylpiperidine group of the formula III ##STR2## in which R and R.sub.1 to R.sub.6 have the meaning indicated in claim 1, are effective stabilisers for organic materials against damage by light, oxygen and heat.

Compounds formed from o-hydroxyphenyl-1,3,5-triazines and sterically

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

Compounds which comprise at least one group of the formula I or II ##STR1## and at least one polyalkylpiperidine group of the formula III ##STR2## in which R and R.sub.1 to R.sub.6 have the meaning indicated in claim 1, are effective stabilizers for organic materials against damage by light, oxygen and heat.

Compositions stabilized by o-hydroxyphenyl-1,3,5-triazines and

A particularly good stabilization against oxidative and light-induced degradation of polyolefines is obtained by adding compounds of the formula I ##STR1## in which R.sup.1 is alkyl, X is dialkylamino, morpholino or alkoxy, and R.sup.2 is hydrogen, alkyl, hydroxyalkyl, allyl, acetyl or acryloyl.

Polyolefines which have been stabilized with

Polyolefins and olefin copolymers which are prepared by polymerization on a catalyst made from a magnesium halide, a titanium compound and an aluminium alkyl can be stabilized by the addition of certain sterically hindered triazinylpiperidines, which are substituted in the 1-position, to the polymerization.

Process for the stabilization of polyolefins

o-Hydroxyohenyl-s-triazines containing suitable functional groups are incorporated in polymers by copolymerisation, copolycondensation, copolyaddition or by polymer-analogous reaction. The modified polymers so obtained have excellent stability to degradation induced by light, oxygen and heat. They can also be used as stabilisers.

Process for incorporating o-hydroxyphenyl-s-triazines in organic polymers

Tetrahydrothiopyran compound of the formula I ##STR1## in which R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, X and n are as defined in claim 1, are effective stabilizers for dyes and dye couplers in photographic layers. In particular, they provide protection from damage by light. They are preferably used in combination with a phenolic antioxidant.

Stabilizers for color photography recording materials

A particularly good stabilization against oxidative and light-induced degradation of polyolefines is obtained by adding compounds of the formula I ##STR1## in which R.sup.1 is not hydrogen.
