The invention concerns an antidegradant blend for polymers, comprising: a. an antioxidant selected from one or more of: i. a phenolic antioxidant; ii. an organic phosphite antioxidant; and: b. an inorganic antioxidant or reducing agent; wherein the composition is absent any metal carboxylate or buffering agent having the capacity to buffer in aqueous solution at a pH range from 4 to 8.

Antidegradant blend

The present invention relates to a precursor material for an insulation composition, comprising: a crosslinkable graft polymer comprising a polyolefin component and a polyene component; and an antioxidant. The present invention also relates to an insulation composition obtained from the precursor material.

Insulation composition

The present invention is directed to an antidegradant blend, comprising: at least one metal carboxylate; at least one inorganic phosphite; at least one phenolic antioxidant; and at least one organic phosphite antioxidant. As examples, the metal carboxylate may comprise a metal stearate, a metal lactate and/or a metal benzoate while the inorganic phosphite may comprise one or more metal hypophosphites.

The present invention refers to dyestuffs of the formula Iwherein

Fibre reactive azo dyes

The present invention refers to dyestuffs of the formula (I)wherein

High light fastness reactive red dyes

The present invention refers to dyestoffs of the formula I wherein Ar is a group of the formula II or of the formula III, D is a group of the formula IV, or of the formula V wherein the variables are defined as given in claim, processes for their preparation and their use for dyeing and printing hydroxy- and/or carboxamido-containing fiber materials.

Fibre reactive scarlet azo dyes

The present invention refers to trisazo dyes of the formula Ior an alkali metal salt thereof; wherein:

Reactive trisazo dyes

The present invention relates to reactive azo dyes of the formula (I) or an alkali metal salt thereof, wherein A is formula (i) or (ii) C is an optionally substituted aromatic or heteroaromatic residue; and R , R , B, D, Y, a, b, c, d and n are defined as given in claim , a process for preparing said dyes and a process for colouring fibre material, which comprises applying thereto said dyes.

Reactive azo dyes

This application relates to reactive dyes having at least one halobenzene nucleus linked to a chromophoric group via an amino linkage and additionally containing a second reactive group.

Reactive dyes containing a halobenzene nucleus

Reactive dyes containing a linkage

Reactive dyes containing piperazine have formula (I)

Reactive dyes containing piperazine

Reactive dyes containing two units each comprising a monoazo or disazo chromophore linked to a triazinylamino group, each of which units is linked by a diamine unit disposed between the triazine rings.
