摘要:
Reactive dyestuffs which are free from anionic groups, in particular sulpho and carboxyl groups, and contain a basic group and a halogenotriazinyl radical, and their use for dyeing and printing synthetic fibre materials. The dyeing obtained are distinguished by good fastness properties, of which, in addition to fastness to sublimation, light and dry cleaning, fastness to wet processing is to be singled out in particular.

Dyestuffs of the formula ##STR1## wherein X, R, R.sub.1, R.sub.2 and R.sub.3 have the meaning given in the description,and their use for dyeing and printing materials containing hydroxyl groups or amide groups, such as textile fibres, filaments and fabrics of wool, silk or synthetic polyamide or polyurethane fibres, and for dyeing and printing natural or regenerated cellulose with dyeings and prints which are fast to washing.
摘要:
##STR1## wherein n, m, p, X, R 1 , R 2 and R 3 have the meaning indicated in the description, and their use for dyeing and printing materials containing hydroxyl groups or containing amide groups, such as textile fibres, filaments and fabrics made of wool, silk and synthetic polyamide fibres and polyurethane fibres and for the wash-fast dyeing and printing of natural or regenerated cellulose.
摘要:
Dyestuffs of the formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, m, n, p and X have the meaning given in the description,and their use for dyeing and printing materials containing hydroxyl groups or amide groups, such as textile fibres, filaments and woven fabrics of wool, silk or synthetic polyamide or polyurethane fibres, and for dyeing and printing natural or regenerated cellulose in dyeings and prints which are fast to washing. Blue dyeings and prints which are fast to light and wet processing are obtained.
摘要:
The dyestuff of the formula ##STR1## is suitable for dyeing synthetic polyamide textile materials, in particular for combination dyeings because of its favorable uptake properties.
摘要:
A phthalocyanine reactive dyestuff mixture having improved color levelness and combination properties comprises at least one phthalocyanine-fluoropyrimidinyl reactive dyestuff 2 and at least one phthalocyanine-vinylsulfonyl reactive dyestuff 1 or at least one phthalocyanine-monochlorotriazinyl reactive dyestuff 3, as well as one or more yellow reactive dyestuffs of the formula 4 to 9.
摘要:
The reactive dyestuffs of the formula ##STR1## wherein the substituents have the meaning given in the description, are particularly suitable for dyeing naturally occurring and synthetic materials containing OH groups and/or amide groups.
摘要:
An underwater camera or instrument having a depressible shutter release button or similar actuator is housed within a flexible plastic waterproof housing. A toggle lever is mounted on the camera with one end overlying the button. Surrounding the lever is a frame member that extends upwardly to separate the housing from the lever so as to prevent water pressure acting on the housing from applying a force on the button.
