    摘要: Described is a process for the level dyeing of polyacrylonitrile materials of slow, normal and rapid absorptive capacity with an aqueous dye liquor, which process comprises using a liquor containing at least one migrating cationic dye as well as, if required, further additives; and adding to the liquor, before, during or after dyeing, at least one organic cationic migration auxiliary.This process renders possible by the use of organic migration auxiliaries the obtainment of level single-shade and, in particular, combination-shade dyeings at normal dyeing temperatures.Particularly suitable migrating cationic dyestuffs are those having a more or less delocalized positive charge, the cation weight of which dyestuffs is smaller than 310, the parachor smaller than 750 and the log P (relative lipophil property) smaller than 3.6.Particularly suitable organic migration auxiliaries are those of which the cation weight is smaller than 250, the parachor smaller than 700 and the log P smaller than 6.4.

    摘要: A piece of porous foil larger than the removable portion of the lid of a can is connected to the under surface of the removable lid portion and overlaps the edges defining the can opening on the interior surface of the lid, whereby liquid is prevented from spurting out of the can with escaping gas upon initial partial opening of the removable portion, and the piece of porous foil is fully removable with the removable lid portion.

    摘要: A process for dyeing polyacrylonitrile materials in clear, neutral blue shades, which comprises the use of a mixture of an oxazine dye of the formula ##STR1## and a naphtholactam dye of the formula ##STR2## in the ratio of 1:3 to 3:1, in which formulae R.sub.1 and R.sub.2 represent low molecular alkyl radicals, R.sub.3 represents a low molecular alkyl radical or an aryl radical, R.sub.4 represents hydrogen or a low molecular alkyl radical, each of R.sub.5 and R.sub.6 represents a low molecular alkyl radical, Y represents a halogen atom and X.sup..crclbar. represents an anion and a dyestuff preparation which contains an oxazine dye of the formula (1) and a naphtholactam dye of the formula (2) in the ratio 1:3 to 3:1.
